Match up two identical Halloween mahjong tiles to clear them from the grid. Only free tiles are fair game; they're the ones not stacked under another tile and with at least one side open. There are 15 levels to tackle in this mahjong adventure. The first 9 levels form the shapes of "H A L L O W E E N," while the last 6 levels are randomized. Feel free to grind this mahjong game as often as you want, with different challenges each time.
