Summer Mahjong is a tile-based puzzle game that involves skill and strategy to clear the board. The game is played with a standard set of Chinese tiles, with two players or up to four players competing to be the first to get rid of all their tiles. The game starts with each player being dealt a set of tiles, and the remaining tiles are placed face down in a draw pile.
Players take turns drawing tiles from the draw pile and discarding one tile from their hand face up on top of a discard pile. The objective is to create valid sets and runs of tiles by matching exposed tiles on the board. A set consists of three or four tiles of the same rank but different suits, while a run consists of three or more tiles of the same suit in sequential order.

Players must carefully plan their moves to create sets and runs that will allow them to get rid of all their tiles before their opponents. Each game is a test of strategy and skill, as players try to outmaneuver each other to emerge victorious.
