There are five variants for each of the 16 puzzles. These include clones of Memory or Minesweeper as well as a poker/solitaire hybrid in which the player's dealt cards and then he must try to place them in a grid to make the best hands. Depending on his score the player then gets rewarded a bronze, silver or gold medal and some coins which can then be spend for access to new cities (and therefore new puzzles) or purchasing new difficulty levels for any already unlocked puzzle.
