Fun Mahjong game for Kids. It starts easy but it gets more difficult every new level.
Combine 2 free stones to remove them from the game. A stone is free if there is no other stone on top and it has at least 1 free side (left or right).
A context menu should be shown when right-clicking or, on touch devices, long-pressing in the game. This menu especially allows to play in full screen and control the volume.
