The player has a choice of six tile layouts - Cat, Turtle, Crab, Dragon, Fortress and Spider, each a stylized portrayal of the respective object or animal. The background image can be chosen from five different options and there are four tile sets, including traditional Mahjong tiles, variations with fuller coloring or larger print, and an alternative pastel tile set with an entirely different picture theme.
Games are not totally random. There is always at least one pair within five tiles of the topmost five tiles in the turtle layout and often two pairs. The algorithm for tile organization positions tiles such that they can mostly be paired on the same level, or otherwise a matching tile is available in an accessible position one level down. It does not check to ensure that the matching tile is not positioned beneath its partner. Thus, there are some games that are impossible to solve.
