Big 2 Poker
This is a game for 2, 3, or 4 players in which each receives 13 cards. The object is to be the first to discard the entire hand.
The player holding the lowest ranked card starts by discarding a card set. Each player, in turn, plays a higher card set or passes. This continues
until 3 players pass. The remaining player then starts a new round with any card set. The game ends when 1 player runs out of cards.
Passing doesn't prevent you from playing subsequent rounds in the same game.
Card and Suit Ranks
In descending order, the cards are ranked 2 A K Q J 10 9 8 7 6 5 4 3 (hence the name, "Big 2".) Again in descending order, suits go spades, hearts, clubs, diamonds - making 3Diamonds the lowest card. Card rank supersedes suit.
Hands are ranked as in Hold'em.
When comparing flushes, the ranks of the 5 cards are compared one by one. If all 5 ranks are identical, the stronger suit wins.
However many cards a player initiates action with, every subsequent hand in that round must discard that number of cards. So, if the first player to act
discards a single card, for the remainder of the round all players are allowed to either discard a single card, or pass.
When a player has 1 card left, the previous player (the assistant) must play the best possible card set to prevent the next player from winning. The assistant can play a multiple-card set, or, if that's impossible, play the highest possible single card.
If the assistant fails to do this, and the next player wins, the assistant covers everyone's losses and can't take money from other players.
When 2 is played alone, or as part of a pair or 3-of-a-Kind, all opponents automatically pass. A player also passes if he/she holds fewer cards than the number of cards played in the preceding hand.
