The game is mostly based on a popular puzzle game type, Mahjong solitaire. This game uses the traditional style of the Mahjong tiles, but instead it is usually played by 1 player and focuses on matching pairs of symbols. The basic goal of the game is to clear all the Mahjong tiles from the board by making pairs of tiles with matching symbols.
Tiles can be matched if they have a matching symbol and have at least one side right or left open. There are some symbols which are not identical which can be matched. These special symbols will be shown in the tutorial. Usually they are common themed, for example detective themed symbols or dragons.
