The rules of the game are slightly different from the classic Mahjong, but there is nothing complicated about them either: - Click on two identical tiles. - Each of the selected tiles must be free on at least one of the 4 sides or both tiles must be next to each other. - The selected pair must be connected by no more than three lines (no more than two corners / turns). - Now select the next pair of tiles and clear the entire field to complete the level.
