Halloween Mahjong

Match pairs of identical tiles to remove them from the board and reveal the tiles under or next to them. The game is over when you have no more identical tiles, you have removed all tiles from the stage or time runs out. If you are stuck, click the shuffle button to re-shuffle the board. You get 20 minutes to play. How many levels can you clear in that time? Have a marvelous time playing Halloween Mahjong!
