A '''trick-taking game''' is a [[card game|card-]] or [[tile-based game]] in which play of a ''[[Hand (card games)|hand]]'' centers on a series of finite rounds or units of play, called ''tricks'' (or, in some settings, ''books''), which are each evaluated to determine a winner or ''taker'' of that trick. The object of such games then may be closely tied to the number of tricks taken, as in '''plain-trick games''' such as [[contract bridge]], [[whist]], and [[Spades (card game)|spades]], or to the value of the cards contained in taken tricks, as in '''point-trick games''' such as [[pinochle]], the [[Tarot card games|tarot]] family, [[briscola]], and most evasion games like [[Hearts (card game)|hearts]].<ref>{{harvnb|Parlett|2008|pages=xvii–xviii}}.</ref> 

'''Trick-and-draw games''' are trick-taking games in which the players can fill up their hands after each trick. In most variants, players are free to play any card into a trick in the first phase of the game, but must ''follow suit'' as soon as the stock is depleted. '''Trick-avoidance games''' like [[reversis]] or [[Polignac (card game)|polignac]] are those in which the aim is to avoid taking some or all tricks.

The domino game [[42 (dominoes)|Texas 42]] is an example of a trick-taking game that is not a card game.

==History==
The earliest [[card game]]s were trick-taking games, as evidenced by the rank-and-[[Suit (cards)|suit]] structure, originating from [[ancient China]] and spreading westwards during the early part of the second millennium. [[Michael Dummett]] noted that these games share various features. They were played without [[trump (card games)|trumps]], following suit was not required but only the highest card of the suit led wins, rotation was counter-clockwise, they were plain-trick games, and the [[pip card]]s of one or more suits were in reverse order so that the lower cards beat the higher ones.<ref name="DummettGame">{{Cite book |url=https://books.google.com/books?id=qqm1AAAAIAAJ |title=The Game of Tarot: From Ferrara to Salt Lake City |isbn=9780715610145 |last1=Dummett |first1=Michael A. E |last2=Mann |first2=Sylvia |year=1980 |publisher=Duckworth }}</ref> 

Two revolutions in European trick-taking games led to the development of ever more sophisticated card games: the invention of trumps, and the requirement of following suit to constrain their power, in the 15th century; and [[bidding]] in the 17th century.

According to card game researcher [[David Parlett]], the oldest known European trick-taking game, [[Karnöffel]], was mentioned in 1426 in the Bavarian town [[Nördlingen]] – roughly half a century after the introduction of playing cards to Europe, which were first mentioned in Spain in 1371.<ref>{{harvnb|Parlett|1990|pages=35, 164}}.</ref> The oldest known game in which certain cards have additional privileges is Karnöffel, where specific ranks of one suit were named ''Karnöffel, Devil, Pope'' etc. and subject to an elaborate system of variable powers. However, these were not trumps in the sense of a suit whose cards uniformly beat all other suit cards.<ref>{{harvnb|Parlett|1990|pages=163–165}}.</ref> 

Around 1440 in Italy,  special cards called ''[[Trionfi (cards)|trionfi]]'' were introduced with such a function. These special cards are now known as ''tarots'', and a deck augmented by tarots as a [[tarot]] deck. The trionfi/tarots formed essentially a fifth suit without the ordinary ranks but consisting of trumps in a fixed hierarchy. One can get a similar effect by declaring all cards of a fixed or randomly determined suit to be trumps. This method, originating with [[triomphe]], is still followed by a number of modern trick-taking games that do not involve an auction.<ref>{{harvnb|Parlett|1990|pages=163–165}}.</ref> 

Trumps were retroactively added to some games, such as [[trappola]]. It is much rarer for trumps to be removed.<ref>{{cite journal|last1=McLeod|first1=John|title=Playing the Game: Austrian Calling Games|journal=[[The Playing-Card]]|date=2013|volume=41|issue=4|pages=235–238}}</ref><ref>McLeod, John. [http://www.pagat.com/marriage/anrufen.html#graden Königrufen (Graden)] at [[pagat.com]]. Retrieved 25 January 2016.</ref> The invention of trumps became so popular that very few European trick-taking games exist without them. This did not stop the two-handed [[piquet]] from becoming the most popular card game in Europe during the 16th century. Parlett suggests the invention of trumps let players in games involving more than two a greater chance of heading a trick.<ref>{{harvnb|Parlett|1990|pages=180}}</ref>

[[File:The Four Friends Playing Hombre.JPG|thumb|"The Four Friends Playing Ombre", 1888, by Malthe Engelstedt]]
The invention of bidding for a trump suit is credited to [[ombre]], the most popular card game of the 17th century. Rather than having a randomly selected trump suit, players can now hold an auction for it. The most popular game of the 18th-century was tarot which experienced a great revival.<ref>{{harvnb|Parlett|1990|page=300}}.</ref> During this time, many tarot games were borrowed bidding over the stock ([[taroc l'hombre]]). In the 20th century, [[whist]], now with bidding and the dummy hand, developed into [[contract bridge]], the last global trick-taking game.

The practice of counting tricks, in plain-trick games, may have originated in the counting of cards won in tricks. It was therefore a logical development to accord some cards a higher counting-value, and some cards no value at all, leading to point-trick games. Point-trick games are at least as old as tarot decks and may even predate the invention of trumps. [[Elfern]] and [[Fünfzehnern]] are possible candidates, although the earliest references date to the 18th century. Nearly all point-trick games are played with tarot decks or [[stripped deck]]s, which in many countries became standard before 1600. Neither point-trick games nor stripped decks have a tradition in England.

While there are a number of games with unusual card-point values, such as [[trappola]] and [[all fours (card game)|all fours]], most point-trick games are in the huge family of [[ace–ten card games]] beginning with [[brusquembille]]. [[Pinochle]] is a representative of this family that is popular in the United States. Other examples include [[belote]] and [[Skat (card game)|skat]].

In contrast to Europe, Chinese trick-taking games did not develop trumps or bidding. They diverged into multi-trick games where melds can only be beaten by other melds provided they have the same number of cards. During the [[Qing dynasty]], these multi-trick games evolved into the earliest draw-and-discard games where the players' objective was to form melds and "go out" rather than capture the opponents' cards. [[Khanhoo]] is an example of a multi-trick game that became a draw-and-discard game.<ref>{{cite journal|last1=Berry|first1=John|title=Chinese Money-Suited Cards|journal=[[The Playing-Card]]|date=2003|volume=31|issue=5|pages=230–235}}</ref> Multi-trick games are also probably the source for climbing games like ''[[Zheng Shangyou]]'' and ''[[dou dizhu]]'', which first appeared during the [[Cultural Revolution]].

==Basic structure==
Certain actions in trick-taking games with three or more players always proceed in the same direction. In games originating in North and West Europe, including England, Russia, and the United States and Canada, the rotation is typically clockwise, i.e., play proceeds to the left. In South and East Europe, South America, and Asia it is typically anticlockwise, so that play proceeds to the right. When games move from one region to another, they tend to initially preserve their original sense of rotation. A region with a dominant sense of rotation may adapt a migrated game to its own sensibilities.<!--This should be enough. It's easy to guess the rotation in former colonies from this.--> For two-player games the order of play is moot.

In each ''hand'' or ''deal,'' one player is the ''[[Dealer (card player)|dealer]].'' This function moves from deal to deal in the normal direction of play. The dealer usually [[Shuffling|shuffles]] the deck (some games use "soft shuffling," where the dealer does not explicitly shuffle the deck), and after giving the player one seat from the dealer opposite the normal direction of play an opportunity to [[Cut (cards)|cut]], hands out the same prescribed number of cards to each player, usually in an order following the normal direction of play. 

Most games deal cards one at a time in rotation. A few games require dealing multiple cards at one time in a ''packet.'' The cards apportioned to each player are collectively known as that player's ''hand'' and are only known to the player. Some games involve a set of cards that are not dealt to a player's hand. These cards form the ''stock.'' (see below) It is generally good manners to leave one's cards on the table until the deal is complete.

The player sitting one seat after the declarer (one with the highest bid and not the dealer) in normal rotation is known as the ''[[eldest hand]],'' also called the ''forehand'' in [[Skat (card game)|Skat]] and other games of German origin. The eldest hand ''leads'' to the first ''trick,'' i.e. places the first card of the trick face up in the middle of all players. The other players each follow with a single card, in the direction of play. When every player has played a card to the trick, the trick is evaluated to determine the winner, who takes the cards, places them face down on a pile, and leads to the next trick. The winner or taker of a trick is usually the player who played the highest-value card of the suit that was led, unless the game uses one or more ''[[Trump (card games)|trump]]'' cards (see below).

The player who leads to a trick is usually allowed to play an arbitrary card from their hand. Some games have restrictions on the first card played in the hand, or may disallow leading a card of a particular [[suit (cards)|suit]] until that suit has been played "off-suit" in a prior trick, called "breaking" the suit, usually seen in cases of a trump or penalty suit. Other games have special restrictions on the card that must be led to the first trick. Usually this is a specific card, e.g., {{Clubs|2}}. The holder of that card is the eldest hand instead of the person one seat after the dealer.

In many games, the following players must ''[[#Follow suit|follow suit]]'' if they can, i.e., they must play a card of the same suit if possible. A player who cannot follow suit may ''slough'' a card, i.e., play a card of a different suit. A trick is won by the player who has played the highest-ranked card of the ''suit led,'' i.e., of the suit of the first card in the trick, unless the game uses a [[#Trumps|trump suit]].

It can be an advantage to lead to a trick, because the player who leads controls the suit that is led and which others must follow. The leading player playing a suit of which he has many decreases the chance that anyone else would be able to follow suit. Playing a suit of which he has few allows him to rid his hand of that suit, known as ''[[Void (cards)|voiding]]'' the suit, freeing him from the restriction to follow suit when that suit is led by another player. 

On the other hand, it can be advantageous to be the final player who plays to the trick, because at that point one has full information about the other cards played to the trick. The last player to a trick can play a card just slightly higher or lower than the current winning card, guaranteeing they will win or lose it by the minimum amount necessary, saving more valuable high or low value cards for situations where they must guarantee that a card played early to a trick will win or lose.

When all cards have been played, the number or contents of the tricks won by each player is tallied and used to update the score. Scoring based on the play of tricks varies widely between games. In most games either the number of tricks a player or partnership has won (''plain-trick'' games), or the value of certain cards that the player has won by taking tricks (''point-trick'' games) is important.

== Partnerships ==
[[File:Bridge demonstratie van Omar Sharif in RAIi, Bestanddeelnr 920-9141.jpg|thumb|Bridge is played between two partnerships]]

In many games such as [[Hearts (card game)|hearts]] and [[oh hell]], all players play individually against each other.

In many four-player games such as [[Contract bridge|bridge]], [[euchre]] and [[Spades (card game)|spades]], the players sitting opposite to each other form a fixed partnership.

Some games such as [[pinochle]] are commonly played with or without partnerships, depending on the number of players.

In some contract/auction games for three or more players, e.g. most [[tarot]] variants, the contractor (''declarer'' or ''taker'') plays alone against all opponents, who form an ''ad hoc'' partnership (the ''defenders'').

In some games the partnerships are decided by chance – the contractor forms a partnership with the winner of the first trick, or with the player who holds a certain card. This practice originated from cinquillo and [[Quadrille (card game)|quadrille]]. In [[Königrufen]] and five-player [[French tarot]] the taker can call out a suit of which he does not possess the king, and is partnered with whomever does have it against the other three. Standard [[Schafkopf]] is similar: A "player" can "call" a suit, and the person holding the ace of that suit becomes his partner for the hand. 

As this is not openly declared, it can be a challenge for the remaining players, to find out who is partnered with whom through cunning playing for several tricks. Aside from that, standard Schafkopf also has several solo options, where the "player" plays alone against the rest. In [[Doppelkopf]], the two players holding the black queens are partners for that hand. Special rules are provided for the case where a single player holds both black queens.

==Stock==
In some games not all cards are distributed to the players, and a ''stock'' remains. This stock can be referred to by different names, depending on the game; ''supply'', ''talon'', ''nest'', ''skat'', ''kitty'', and ''dog'' are common game-specific and/or regional names.

In some games the stock remains untouched throughout play of the hand. It is simply a pile of "extra" cards that will never be played and whose values are unknown, which will reduce the effectiveness of "[[Card reading (bridge)|counting cards]]", a common strategy of keeping track of the cards that have been played or are yet to be played. In games without bidding, trumps may be decided by exposing a card in the stock as in [[Triomphe]]. 

In other games, the winner of an auction-bidding process, the taker or declarer, may get to exchange cards from his hand with the stock, either by integrating the stock into his hand and then discarding equal cards as in [[Skat (card game)|Skat]], [[Rook (card game)|Rook]] and [[French tarot]], or in a "blind" fashion by discarding and drawing as in [[Ombre]]. The stock, either in its original or discarded form, may additionally form part of one or more players' "scoring piles" of tricks taken; it may be kept by the declarer, may be won by the player of the first trick, or may go to an opposing player or partnership.

In some games, especially two-player games, after each trick every player draws a new card. This continues while the stock lasts. Since this drawing mechanism would normally make it difficult or impossible to detect a revoke (for instance, the player may not be able to follow suit, so they play off-suit and then immediately draw a card of the suit led), in the first phase of trick-play (before the stock is empty) players generally need not follow suit. A widespread game of this type is the [[Marriage group]].

== Bidding ==

In a ''contract'' game the winning and scoring conditions are not fixed but are chosen by one of the players after seeing their hand. In such games, players make ''bids'' depending on the number of tricks or card points they believe they can win during play of the hand. One or more of these bids stands as the ''contract'', and the player who made that bid is rewarded for meeting it or penalized for not meeting it.

In ''auction'' games, bidding players are competing against each other for the right to attempt to make the contract. In a few games, the contract is fixed, normally a simple majority, less often based on certain cards captured during play, and players' bids are a wager of game points to be won or lost. In others, the bid is a number of tricks or card points the bidder is confident that they or their partnership will take. Either of these can also include the suit to be used as trumps during the hand. 

Common bids include slam (winning all the tricks), [[misère]] (losing all the tricks), ouvert (the contractor's hand is exposed), playing without using the stock or only part of it, and winning the last trick or other specific tricks. The highest bid becomes the contract and the highest bidder is the ''contractor'', known in some games as the ''declarer'' or ''taker'', who then plays either with or without a partner. The other players become ''opponents'' or ''defenders'', whose main goal is to prevent the contract being met. They may announce a ''contra'' against the contractor which doubles the points for the hand. The contractor can declare a ''recontra'' which will double the points again.

Popular examples of games with auctions include [[Contract bridge]], [[Pinochle]], [[Tarot card games|tarot games]], [[Skat (card game)|Skat]], [[Belote]] and [[Twenty-eight (card game)|Twenty-Eight]]. In many auction games the eldest hand leads to the first trick, regardless of who won the auction, but in some, such as [[Contract bridge|Contract Bridge]], the first lead is made by the player next in rotation after the contractor, so that the contractor plays last to that trick.

In ''precision'' or ''exact-prediction'' games, all players choose their winning condition independently: to win precisely a predicted number of tricks ([[oh hell]]) or card points ([[Jass|Differenzler]]). Each player's bid stands. In partnership games the partners' bids are often combined. Each player or partnership then tries to take exactly the number of tricks or points they bid, and are rewarded or penalized for doing so independently of anyone else's success or failure in meeting their bid. This type of game began to mature in the 20th century.<ref>{{harvnb|Parlett|1990|pages=311–315}}.</ref> Other games generally falling into the exact-prediction category are [[Spades (card game)|Spades]] and [[Ninety-nine (trick-taking card game)|Ninety-Nine]].

==Trumps==
[[File:Escáner 20160104 (5).jpg|thumb|A 6 of cups is tucked under the deck in a game of [[Brisca]], to show that cups is the trump suit]]
''[[Trump (card games)|Trump cards]]'' are a set of one or more cards in the deck that, when played, are of higher value than the suit led. If a trick contains any trump cards, it is won by the highest-value trump card played, not the highest-value card of the suit led.

In most games with trumps, one of the four suits is identified as the ''trump suit''. In the simplest case, there is a static trump suit such as the Spade suit in the game [[Spades (card game)|Spades]], or a dedicated trump suit in the [[Tarot card games|Tarot]] family, in addition to the other four, is featured. More often, a dynamic trump suit is determined by some means, either randomly by selection of a card as in [[oh hell]] and the original form of [[Whist]], or decided by the winner or winning bid of an auction as in [[contract bridge]] and some forms of [[Pinochle]]. 

In certain games, such as Rowboat and Rage, the trump suit may change during the course of the hand, even from trick to trick. Some psychological variety is added to the game and makes it more difficult to cheat if the trump suit is only chosen after dealing.

In some games, in addition to or separately from a trump suit, certain fixed cards are always the highest trumps, e.g. the Jacks in [[Skat (card game)|Skat]], the Jacks or Jokers in [[Euchre]], and the Rook Bird card in [[Rook (card game)|Rook]]. They are called ''matadors'' after the high trumps in [[Ombre]]. ''Matadors'' either have high point values or special abilities as in [[Spoil Five]] where they can revoke legally.

Some games have more than one trump suit, such as the quasi-trick game [[Stortok]], in which there are two trumps, with one superseding the other. Other games have no trumps. [[Hearts (card game)|Hearts]] for instance has no provision for a trump suit of any kind. The Hearts suit for which the game is named has a different significance. Though trump is part of [[contract bridge]], teams can make bids that do not specify a trump suit, called [[notrump]]. If that is the winning bid, then there is no trump suit for that hand. Making such a contract is regarded as harder to accomplish.

In most cases for "no trump" deals, any card other than the leading suit played has no value. In some games such as [[Oh, hell]], where the player may need to not get more tricks to win, playing cards other than the leading suit can be useful.<ref>McLeod, John. [http://www.pagat.com/exact/ohhell.html Oh Hell!] at [[pagat.com]]. Retrieved 18 February 2017.</ref>

==Declarations==
[[File:King and Queen of Clubs.jpg|thumb|In Belote, a "Belote" is a pair of a King and a Queen of the trump suit: it must be declared when the first is played]]
In some games such as [[Piquet]], [[Tarocchini]], and [[Belote]], before the taking of tricks commences, players can expose certain cards or [[Meld (cards)|melds]] (combinations) that they possess for bonus points. While this phase may seem to award players for pure chance, those who do declare risk letting their opponents develop strategies to counter the cards that they have revealed.

==Follow suit==
In many games, ''following suit'' is the action of playing a card of the same suit as that of the leading suit. A player must follow suit if that player has cards of the leading suit in his hands. There is a large variation of strictness in following suit among games.<ref>McLeod, John. [https://www.pagat.com/mech.html#followsuit Mechanics of Card Games] at [[pagat.com]]. Retrieved 18 February 2017.</ref>

In most modern games with trump suits, the rules for following suit do not distinguish between the trump suit and the ''plain suits''. If a trick begins with a plain suit card and a later player cannot follow suit, the player may choose freely to either ''slough'' (discard a card of another plain suit), or ''ruff'' (''trump'' the trick by playing a trump card). Subsequent players to the trick must still follow the original suit, and may only discard or trump if they do not hold a card of the suit led. 

Certain games are "play to beat" or "must-trump". If a player cannot follow suit but can play trump, they must play trump. If they are able, they must beat any trump card already played to the trick. [[Pinochle]] and several of the [[Tarot card games]] have this rule.

Some games, notably [[French tarot]] and a variation of [[Rook (card game)|Rook]], use a special card (in French Tarot's case, the [[The Fool (Tarot card)|Excuse]]) that can be played at any time. If not, he has the choice of playing a trump to possibly win the trick, or rough (waste) a different suit.

If unable to follow suit or trump, any card can be played. Each trick must contain one card per player, and hence a player unable to satisfy any other instruction is at liberty to play any card. Usually a low-ranking card or one from a short suit is sacrificed. The former is used to protect a higher ranking card while the latter is to help void a suit so as to allow trumping a future trick.

For example, consider the following [[Whist]] hand, in a game where diamonds {{cards|d}} are the trump:
* North holds: {{cards|As|Ks|4h|9d}}
* East holds: {{cards|7s|5d|Qc|10c}}
* South holds: {{cards|3h|2d|Jd|Ac}}
* West holds: {{cards|5s|2s|6h|5c}}

North leads the deal with {{spades|K}}. Now, all the other players must follow suit, i.e. play a spade card. East has a spade card, and thus must follow suit by playing {{spades|7}}. South, however, does not have any spade card, and thus is allowed to play any card he wants. If he desires to win the trick, he can override North's {{spades|K}} by playing a diamond card (diamond being the trump), for example {{diamonds|J}}. If he does not want to win the trick, he can slough any other suit, such as {{hearts|3}}. Let us assume that he plays {{diamonds|J}}, overriding North's card. Now, West still has to follow suit, since he has a spade card, and plays {{spades|2}}. South's trump card, gives him an opportunity to escape following suit, and he wins the trick.

If a player who can follow suit does not do so, or in games with additional restrictions on card play, not following these restrictions is known as a [[revoke]], or 'renege'. A revoke typically cannot be discovered at the time when it is committed, but when a player plays off-suit to a trick, competent opponents will make a mental note that the player does not hold the suit led, and will notice later if the player later plays a card of the suit they were thought to be void in. The situation is similar for other types of revoke. 

Most game rules prescribe a severe penalty for a revoke and may also result in the hand being voided, a "misdeal". Decks of cards have been marketed for trick-taking games with the traditional French suit symbols, but in four colors. These are often called [[Four-color deck|"no-revoke" decks]], as the color contrast between each suit makes a potential revoking play easier to spot and harder to do accidentally.

In some trick games—typically ones in which players are not penalized for winning tricks, and there is no requirement for trumping or following suit when possible—players may ''slough'', or play a card face down.  A card so played is incapable of winning the trick; but sloughing has the advantage that the other players cannot see what card is played. As this form of sloughing has the potential to be used to cheat in most games (i.e. playing a winning card face-down to avoid taking an "overtrick" or a trick containing penalty points) and is thus not allowed. ''Sloughing'' in the vernacular more often refers to simply discarding an off-suit card on a trick, particularly one that could be dangerous to that player if kept. 

This form of sloughing is important in evasion games and in some contract games where "overtricks" are penalized. In [[oh hell]], for instance, a player who cannot follow suit may elect to discard a card that would win if played to follow suit later, thus reducing the chance that the player will "bag", or take more tricks than needed. This is common in [[Hearts (card game)|Hearts]], where high-value cards are dangerous, especially Spades and Hearts, as they increase the chance of winning a trick with penalty points.

Some games such as [[Pinochle]] and [[Sheng ji]] use several decks shuffled together. In these games, there may be several equal winning cards in a trick; such games then use other rules to break ties. Common rules include:
* the first-played of the tying cards wins
* the last-played of the tying cards wins
* The tying cards cancel each other out, and the trick is taken by the next-highest card that was played.
* The tying cards cancel each other out, but the trick is spoiled (ignored).

A common additional rule to reduce these occurrences is that a player cannot play a card tying the current high card unless they would renege or fail to overtrump by making any other play.

==Scoring==
When all tricks have been played, the winner of the hand and the players' scores can be determined. The determining factor in plain-trick games, the most popular form of trick-taking games in English-speaking countries, is simply how many tricks each player or partnership has taken. In point-trick games, certain card values are worth varying points. The players sum the points from cards in their "scoring piles" that were accumulated by taking tricks. 

Points for cards, and the method of counting points, vary by game. In Rook, for example, the 5-card of each color is worth 5 points, the 10 and 14 (or Ace) is worth 10, and the Rook Bird (or Joker) is worth 20, while all other cards are worth nothing. Many Chinese card games like Finding Friends use a very similar system, in which each 5-card is worth 5 points, and the 10 and King are each worth 10 points.<ref>Rules for Chinese trick-taking card game [http://www.zhao-pengyou.com/ "Finding Friends (Zhao Pengyou)"]. Retrieved on 7 September 2018.</ref> 

Pinochle has many popular scoring variants usually based on point values for face cards and Aces, while pip cards score no points. In French tarot, all cards have a value including a half-point, and are traditionally scored in pairs of a high-value and a low-value card which results in a whole-point value for the pair.

In the most common ''positive'' or ''race'' games, players seek to win as many tricks or card points as possible. To win a hand, a player typically needs to win a minimal number of tricks or card points; this minimal threshold is usually called the "contract", and may be defined by the game's rules (a simple majority of total available points or tricks, or tiered thresholds depending on which player or side has captured certain cards), or the result of an "auction" or "bidding" process. A player who wins more than the number of tricks or card points necessary for winning the hand may be rewarded with a higher score, or conversely (in exact-prediction games) they may be penalized.

There are also ''negative'' or ''evasion'' games, in which the object is to avoid tricks or card points. E.g. in Hearts each card point won in a trick contributes negatively to the score. A special type is ''misère'' games, which are usually variants of positive games which can only be won by not winning a single trick.

Other criteria also occur. Sometimes the last trick has special significance. In ''marriage games'' such as Pinochle the winner of the last trick receives 10 points in addition to the card points, while in ''final-trick'' games such as cắt tê only the winner of the last trick can win a hand. There are also blends between positive and negative games, e.g. the aim may be to win a certain prescribed number of tricks. Many card games, regardless of their normal scoring mechanism, give bonuses to players or partnerships who win all tricks or possible points in a hand, or conversely lose all tricks or points.

Games usually end after every player has had an equal chance to be the dealer. The number of rotations varies widely among games. Some games have a cumulative score where all points from each hand add up. Others assign only a set number of game points for winning a hand. For example, a player or side that wins one hand may be awarded one game point, two if they achieve a slam. The player or side with the most game points or the first to reach a certain number of card or game points, is considered the winner.

==Special variations==
=== Variations to basic rules ===
Numerous further variations to the basic rules may occur, and only a few examples can be mentioned here:
* Certain games require the holder of a certain card value to play it as the lead to the first trick of a hand; [[Hearts (card game)|Hearts]], as commonly played in North America, requires the player holding the {{Clubs|2}} to play it as the lead-off card. Variants of [[Pinochle]] sometimes require the first player to the left of the dealer that holds a ''dix'' ({{Clubs|9}}) to lead off.
* There may be restrictions on leading certain suits; a common Hearts rule is that a player may not lead a Heart until at least one trick has had a Heart played off-suit to another trick. Spades has a similar but less-common variation regarding its trump suit.
* There are trick-taking games played with [[Domino]] tiles instead of playing cards. These include the Chinese [[Tien Gow]] and [[42 (dominoes)|Texas 42]]. Giog is played with [[Xiangqi|Chinese chess]] tiles.
* Many games are played with one or more ''[[stripped deck]]s'' (a deck from which certain card values are removed). The most common stripped deck is a [[piquet deck]], used for [[piquet]], [[Belote]], [[Skat (card game)|Skat]], [[Euchre]], [[Bête]], [[Écarté]], [[Bezique]] and (with two piquet decks) [[Pinochle]], among others. [[Rook (card game)|Rook]]'s main variant, Kentucky Discard, uses the equivalent of a 52-card deck with all card values 2–4 removed. Most regional [[Tarot]] variants, especially Central European and Italian variants like Tarock and Tarocco, use some subset of the "full" 78-card Tarot deck.
* In Bridge the partner of the contractor or ''declarer'' is called ''dummy'' and does not actively participate in the play; dummy's hand is instead laid on the table face-up after the opening lead, and declarer chooses the cards from dummy's hand to play during dummy's turns.
* In [[Karuta#Unsun Karuta|Hachinin-meri]] and Truf, trumps are played face down. When the trick is finished, the trumps are revealed to see who won the trick.<ref>{{cite journal|last1=Depaulis|first1=Thierry|title=Unsun, a Far-eastern Cousin of Ombre|journal=[[The Playing-Card]]|date=1983|volume=12|issue=1|pages=39–44}}</ref><ref>McLeod, John. [http://www.pagat.com/exact/truf.html Truf] at [[pagat.com]]. Retrieved 25 January 2016.</ref>
* In many trumpless games that do not require following suit, sloughing is done face down. This is done in [[Madiao]], [[Tien Gow]], [[Tam cúc]], [[:zh:六虎牌|Six Tigers]], [[Ganjifa]], [[Kaiserspiel]], and Brazilian [[Truco]].
* Some cards lose their trick-taking power if they are not led or played in a specific trick as in [[Karnöffel]], [[Tien Gow]], and [[Ganjifa]].
* In [[tarot game]]s played outside of Central Europe, [[The Fool (Tarot card)|the Fool]] is a special card that excuses the player from following suit. Except in rare circumstances in some games, it can neither capture nor be captured. Usually a non-counting card is given as compensation to the trick's winner by the Fool's owner.

=== Rules in Austrian and German games ===
In games derived from Austria and Germany, trick-taking is governed by the rules called ''Zwänge''. The three main ones are ''Farbzwang'', ''Stichzwang'' and ''Trumpfzwang''. Although they broadly equate to rules in English-speaking countries, there are no single-word equivalents. For many games of this type, applying these rules correctly is crucial to the type of contract being played.

==== ''Farbzwang'' ====
''Farbzwang'' (or ''Bedienzwang'') literally means "suit compulsion" and is the rule that players must follow the suit of the first card to be led to the trick, provided that they have a card of that suit. If a player does not have a card of the led suit, rules vary depending on whether the other ''Zwänge'' apply.

==== ''Stichzwang'' ====
''Stichzwang'' means "trick compulsion" and is the rule that players must attempt to win the trick if they are able, either by playing a higher card of the led suit or by playing a trump card to a [[side suit]] lead.

==== ''Farbzwang'' with ''Stichzwang'' ====
Some games apply ''Farbzwang'' and ''Stichzwang'' together, which means that a player, when it is his  or her turn, must:
* take the trick with a higher card of the led suit. If unable to do so, the player must
* discard a lower card of the led suit. If that is not possible, the player must
* take the trick with a trump card, but if that is also not feasible, the player may
* discard any card.

''Farbzwang'', the requirement to follow suit, almost always takes precedence over ''Stichzwang''. A player is not allowed to take the trick with a trump if able to follow suit. There are rare instances where e.g. [[All Fours (card game)|All Fours]] rules apply i.e. a player with a card of the led suit may either follow suit or trump, but only if unable to follow may a player discard.

==== ''Trumpfzwang'' ====
''Trumpfzwang'' means "trump compulsion" and requires that a player ''must'' play a trump if unable to follow suit. In other words, the player may not simply discard, if unable to follow.

''Example'': Acorns are trumps. Peter is forehand and plays the 8 of Bells, middlehand trumps with a 10 of Acorns; Anna is rearhand and has no Bells, but does have a trump card, the 8 of Acorns. She must play this and cannot discard another non-trump card in order to keep the trump for a subsequent trick.

==== ''Tarockzwang'' ====
''Tarockzwang'' is used in [[tarock game]]s such as [[Königrufen]] and [[Tapp-Tarock]] and means "Tarock compulsion" or the requirement to play a Tarock card if one is led to the trick or if a player is unable to follow suit. It is a form of ''Trumpfzwang''.

== Examples ==
Trick-taking games may be divided into point-trick games and plain-trick games. Examples of each are as follows:

=== Point-trick games ===
Point-trick game are those in which win or loss is determined by the total value of the "counters" in the tricks.<ref name="parlett,2008,644–645">{{harvnb|Parlett|2008|pages=644–645}}.</ref> The counters are cards with a point value, sometimes referred to as "card points" to avoid confusion with "game points" awarded for winning the game and/or bonuses.

Examples include:

{{Div col|colwidth=20}}
* [[Bavarian Tarock]]
* [[Belote]]
* [[Bézique]]
* [[Binokel]]
* [[Briscola]]
* [[Clabber]]
* [[Doppelkopf]]
* [[Jass]]
* [[Pinochle]]
* [[Schafkopf]]
* [[Schnapsen]] or [[Sixty-six (card game)|Sixty-six]]
* [[Sheng ji]]
* [[Skat (card game)|Skat]]
* [[Tarock (card games)|Tarock]] games ([[French Tarot]], [[Königrufen]], [[Zwanzigerrufen]], etc.)
* [[Trappola]] (Bulka)

{{Div col end}}

=== Plain-trick games ===
Plain-trick games are those in which the outcome is determined by the number of tricks taken, regardless of their content.<ref name="parlett,2008,644–645"/>

Examples of plain-trick games include:

{{Div col|colwidth=20}}
* [[Boston (card game)|Boston]]
* [[Contract bridge|Bridge]]
* Callbreak
* [[Écarté]]
* [[Ombre]], [[Bête]], and [[Quadrille (card game)|Quadrille]]
* [[Piquet]]
* [[Préférence]]
* [[Solo Whist]]
* [[Spades (card game)|Spades]]
* [[Tippen]]
* [[Watten (card game)|Watten]]
* [[Whist]]

{{Div col end}}

In games that consist of several successive, different, trick-taking contracts, such as Herzeln or Quodlibet, it is not possible to categorise them as either point- or plain-trick games.

=== Last trick games ===
In a very few games the aim is to win the last trick. These include:

* [[Agram (card game)|Agram]]
* [[Femkort]]
* [[Letzter Stich]]
* [[Toepen]]

=== Trick-avoidance games ===
Trick-avoidance games are those in which the aim is to avoid taking certain tricks or to avoid taking all tricks. [[Misère|Misere]] or [[Bettel (cards)|bettel]] are contracts in which the declarer undertakes to win no tricks. There are also contracts like Piccolo in the game of [[Königrufen]], in which the aim is to take only one trick. Examples include:

* [[Bassadewitz]]
* [[Gong Zhu]]
* [[Grasobern]]
* [[Hearts (card game)|Hearts]]
* [[Polignac (card game)|Polignac]]
* [[Slobberhannes]]
