Big Two Rule (Base on Hong Kong/Pusoy Dos/International Rule) Big Two (also known as Deuces, pusoy dos, 大老二, 鋤大D) is a card game similar to the game of A*****e, Crazy Eights, B******t, Winner, and other shedding games. Common game played with four players. The objective of the game is to be the first to get rid of all of your cards. Cards may be played as singles or in groups of two or five, in combinations which resemble poker hands. The leading card to a trick sets down the number of cards to be played; all the cards of a trick must contain the same number of cards. The combinations and their rankings are as follows. Single Card Ranking: 2->A->K->Q->J->.....->3 Suit: Hong Kong:Spade>Heart>Club>Diamond Taiwan:Spade>Heart>Diamond>Club Pusoy Dos:Diamond>Heart>Spade>Club Single cards: Any card from the deck, ordered by rank with suit being the tie-breaker. Pairs: Any two cards of matching rank, ordered as with singular cards by the card of the higher suit. Triples: Any Three card of matching rank, order by rank. 5-card hand: Uses the same ranking as Poker. There are five (var. 2) different valid 5-card poker hands, ranking, from low to high, as follows (the same ranking as in poker): Straight : Any 5 cards in a sequence (but not the same suit). There isn't JQKA2, while A2345 is largest 23456 is 2nd largest. (For taiwan game, A2345 is the smallest while 23456 is largest) Flush: Any 5 cards of the same suit (but not in a sequence). Rank is determined by highest value card and then by highest suit. Full House: a composite of a three-of-a-kind combination and a pair. Rank is determined by the value of the triple. Four of a kind + One card : Any set of 4 cards of the same rank, plus any 5th card. Straight Flush: A composite of the straight and flush: five cards in sequence in the same suit. Each player got 13 cards. At the beginning of each game, the player with the smallest card(Diamond 3 in Hong Kong, Club 3 in Pusoy Dos or Taiwan) starts by either playing it singly or as part of a combination, leading to the first trick. Play proceeds counter-clockwise, with normal climbing-game rules applying: each player must play a higher card or combination than the one before, with the same number of cards. Players may also pass, thus declaring that he does not want to discard any cards (or does not hold the necessary cards to make a play possible). A player need to warn others when he/she is one playing combination away from winning. The goal is, then, for the other players to play (and get rid of) as many cards as possible while avoiding the combination that would allow the calling player to win the game. For example, if the said player has one last single card, the other players would play pairs or other combinations to force him/her to pass. If the other players doesn't do that, it is known as illegal assist. 3X Penalty will be applied. The game ends when one player runs out of cards.
