Click on matching pairs of Halloween tiles to eliminate them. Only tiles that are not covered and are not surrounded on both the left and right by other tiles can be selected. There are two pairs of 36 different tiles for a total of 144 tiles. You get 100 points per pair found, -100 every time you use the Hint button, and you lose 1 point per second. The hint button will highlight a selectable pair only if one remains. Not all arrangements can be completed. Use the New button to restart the game with a new arrangement.
