Editing 500 (card game) (section)

==Variations==
{{Unreferenced section|date=March 2021}}
There are variations of the rules concerning the size of deck, use of the joker, bidding after pass etc.

=== Bidding after pass ===
Some play that it is allowed to bid after pass if someone hereafter changes the suit of their bid.<ref>{{Cite web|url = https://www.play500.com/gameof500.html|author = Bryce Francis|title = The card game of 500 According to Francis:The game of 500 |quote = Any player changing the suit of any call he makes at any time gives all players the right to re-enter the bidding.}}</ref>

=== Raising own bid by the winner ===
Some play that the winner of the auction can raise their bid.<ref name="Pagat"/><ref name = "The game of 500">{{Cite web|url= https://www.play500.com/gameof500.html|author = Bryce Francis|title = The card game of 500 According to Francis: The game of 500}}</ref> If they change their suit (or no trumps) other players are allowed to bid again.<ref name = "Pagat"/><ref name = "The game of 500"/> If they only raise their bid without changing the suit, other players cannot bid again.<ref name = "Pagat"/><ref name = "The game of 500"/> Moreover, it is a common convention that, if only one player partakes in the auction (other players pass), they cannot raise their bid.<ref name = "Pagat"/><ref name = "The game of 500"/>

===Joker in no trump ===

The use of the joker in no trumps (including misère) may vary. In some versions a player may lead a trick with the joker by naming the suit to be followed, but may not name a suit to which the player has previously claimed to be void.<ref name = "Pagat"/> In some variations, a player may not "renege" with the joker – that is, use it as a card of a suit in which the player has already claimed to be void (unless the joker is the only card in the player's hand). In some variations, the joker may only be played as the first or last card in a suit.

===Walker Ultimate 500===
{{Unreferenced section|date=March 2021}}

A variation in which the winning team/player must win exactly 500 points.  The game is played as normal, with the additional rule that 1000 points (like negative 500 points) loses the game. "Peggings" (or "Scab Points"){{explain|date=June 2022}} must be played.  This variation usually (not always) results in a longer game and generates more complex bidding and play.

=== Misère ===
Local variants may exclude either ''open misère'', ''misère'' or both.

===French Canadian variation===
{{Unreferenced section|date=March 2021}}

A variation for four players using two Jokers ("bonhommes") and a standard 52-card pack stripped of 2s and 3s. The white Joker ("la blanche") is considered stronger. The players are dealt 10 cards each in batches of 3–3–4. When 3 are passed, another 3 go to the kitty ("chatte", middle of the table). There should be 6 cards in the middle after the deal. Some variations allow for the final card placed in the kitty to be turned upright for all players to see.

The attacking player takes the kitty and discards six cards of their choice, and no other player may see them. The bidding goes accordingly with the other variation, and Misère ("Nulot") may be allowed. The "petite" misère is equal to 500 points and can only be outbid by 8NT while "la grosse" or open misère is worth 1000 points and can only be outbid by 10NT (the latter is distinguished in that all cards are placed face-up on the table).

The game is played to a total of 1000 points. If a team fails to fulfil its contract, the points are added to the other team's total. Points are never subtracted.

===Set rule===
{{Unreferenced section|date=March 2021}}

The game may be played with a standard variation known as ''setting''. An opponent is ''set'' when they fail to fulfill a contract by a predetermined number of bids. The point system and scoring remain as per standard, but an opponent who is awarded the kitty and is subsequently set is not allowed to bid in the next round. Note that it is only the player awarded the kitty (not all players on the team) that is not allowed to bid in the next round. In the case of a set occurring during double misère the player who touches the kitty first is not allowed to bid in the next round.

Typically, the set occurs at one trick more than is actually necessary to break the bidding team's contract. In other words, 5 tricks in a 7-trick bid, 4 tricks in an 8-trick bid, 3 tricks in a 9-trick bid, 2 tricks in a 10-trick bid. However, for misère, open misère, and double misère a set always occurs at 3 tricks.

===Breach rule (related to the set rule)===
{{Unreferenced section|date=March 2021}}
Breach indicates that a non-bidding team intends to breach the contract of a bidding team by at least one more trick than is actually necessary to break the contract. As opposed to the Setting rule, Breach must be called on a per hand basis, and does result in additional scoring. Typically, Breach is not played in a game when the setting rule is being used.

A single player from a non-bidding partnership may call to breach another team's contract after a successful bid for a seven-trick (or more) contract has been made. The breach call may be made before or after the contracting team picks up the kitty, but must be made before game play starts. Typically, a breach occurs at one trick more than is actually necessary to break the bidding team's contract. In other words, 5 tricks in a 7-trick bid, 4 tricks in an 8-trick bid, 3 tricks in a 9-trick bid, 2 tricks in a 10-trick bid. However, for misère, open misère, and double misère a breach always occurs at 3 tricks.

A breach call can result in three different scenarios:

;Win/lose: If the bidding team successfully fulfills its contract, then it receives the full points of the original bid, and the team calling breach loses points.

;Lose/lose: If the bidding team does not fulfill its bid, but the opposing team does not take the necessary number of tricks to perform a breach, then the bidding team loses the point value of the original bid, and the team calling breach loses the predetermined value of the breach call.

;Lose/win: If the bidding team loses its bid by the pre-established number of tricks, then the bidding team loses the contract points, and the team calling breach gains the predetermined value of the breach call.

Because breach is not considered an actual bid, a team may not win or lose (“go out the back door”) based on points gained or lost from a breach call.

A player who calls breach but does not fulfill the conditions of breach (win/lose or lose/lose scenario) is not allowed to bid in the next round. A player who bids a seven-trick contract but is successfully breached by an opponent (lose/win scenario) is not allowed to bid in the next round.

===Point spread rule===
{{Unreferenced section|date=March 2021}}

A variation on the score keeping, the point-spread rule ends the game when one team has a negative score and the other team has a positive score, which results in a point spread of 500 or more points.
