Mahjong is a very popular Chinese Game. To complete a game you must clear the board of stones and not bring down the pyramid. To clear the stones you need to match 2 stones of the same design. They pyramid consist of 234, 164, 114, 64 and 40 stones. Try not to make a mistake as you can only use the “back” button to undo one move at a time, and you will loose the points you earned for that move!
