Chengdu mahjong, also known as Sichuan mahjong or "Bloody Battle to the End," is a popular and fast-paced variation played with 108 tiles consisting only of three suits: dots (cookies), bamboos (sticks), and characters, with all honors, winds, and dragons removed. The game typically involves four players, each starting with 13 tiles, except for the dealer who starts with 14. A unique and defining rule of this style is the "forbidden suit," where each player must choose one of the three suits to completely discard from their hand; a hand cannot be considered a winning "Hu" if it still contains tiles from this chosen forbidden suit. The objective is to form a hand of 14 tiles consisting of four sets—either three-of-a-kind (Pung) or a sequence of three (Chow)—and one pair. Unlike other versions where the game ends after the first person wins, Chengdu mahjong continues until three players have declared "Hu" or the wall of tiles is exhausted. This "bloody battle" format means winners stop playing but losers continue to play against each other, allowing for multiple winners and strategic depth as players decide whether to aim for a quick, cheap win or a more complex, high-scoring hand. Players can claim a discarded tile to complete a three-of-a-kind (Peng) or a four-of-a-kind (Gang), but unlike many other styles, they cannot claim a discard to complete a sequence (Chow) unless it is for the final winning tile. Scoring is typically calculated based on the complexity of the hand and the number of "Gangs" achieved, with payments made immediately or at the end of the round.
