A player can only remove the tiles one pair at a time. There are a total of 72 pairs in a game of MahJong solitaire. Like cards, the tiles have standard suits. These suits are Characters, Bamboos, Circles, Dragons, Winds, Seasons, and Flowers.
When matching pairs, Seasons and Flowers are the only suits you do not need to match exactly. Any Season or Flower combination counts as a pair because there is only one of each tile.
When you have no more pairs, the game is over. If you clear the board, you win.
From the menu, you can start a new game or continue an old one. In the game there are options. You can set the display of the number of free pairs, to fix the position of the screen in landscape mode and more.
