Mahjongger is similar to the ancient Chinese game of mahjong (solitaire). Game is intended for children and promotes development of figurative thinking. The goal of the game is to eliminate all tiles on the board by matching pairs of free tiles. A tile is "free" (and can be matched) only if it is a top-most tile and has either a right or left edge with no neighbouring tile. You collect points by matching pairs of tiles. You lose the game if there is no possible move left (you cannot shuffle the tiles again in this case). You win the game if all tiles are eliminated from the board. If you manage this in a good time, you can enter your name into the highscore list.
