Halloween Diamond Mine Mahjong is a Halloween themed Mahjongg matching puzzle game with a layout shaped like a Diamond Mine. The tiles images have a Halloween theme instead of the typical Chinese icons. You can play in full screen mode or create your own puzzle layouts and play them. Earn coins by completing levels, and use them to buy hints or shuffles in the game.

If you're unfamiliar with Mahjongg, it is a simple matching game where you try to pair up two tiles that have the same image on them to remove the tiles from the game. To make things a little more difficult, you can not remove a tile if that tile is partially covered by a tile above it, or if the tile has a tile blocking it on both the left and the right side. To make it more apparent which tiles can be removed, this version of Mahjongg has tiles dimmed if they can not be selected. To remove two tiles, click the first tile to highlight it, then click the second tile. If the tiles match, and can be selected, both tiles will be removed from the game board.
