Tichu is a popular card game that originated in China and is played with a standard deck of 52 cards plus four jokers. It is typically played by four players in two partnerships. The objective is to be the first team to reach a score of 1000 points by winning tricks and declaring special hands. Players take turns playing cards, aiming to beat the previous play. Unique combinations, such as pairs, straights, and full houses, can be played. The game also includes strategic elements like declaring a Tichu, which can earn bonus points.
