Popular addictive free game for kids and everybody by Game-Mahjong.com
Find identical tiles and click at them to delete. But pay attention that the tiles should be unlocked, i.e. no tile above-below or to the left-right. Tiles with figures and pets with text match even if they are not identical. Cartoon Mahjong is extremely bright, colorful and relaxing.
This game is played with mouse only.
