Japanese Mahjong is a completely different game from the tile-matching Mahjong Solitaire. A cross between Gin Rummy and the fictional Dragon Poker, this is one game that will definitely take a while to learn, and even longer to master.

Brand new from Yoshio Ishii of Nekogames, creator of Hoshi Saga, comes a simple mahjong-based puzzle game called Slidon. With a little mouse-based grace, your only goal in Slidon is to push tiles around a grid to form matching pairs of two or more. When like tiles meet, they vanish. You have a limited number of moves to complete each stage, so keep your tile shoving in check and study the board carefully.

From the Gorillaz' website comes Tiles of the Unexpected!, a game which puts a new spin on a familiar genre. Like a cross between SameGame and Mahjong, the challenge is to clear all of the tiles from the board. Click on any set of two or more adjacent, identical tiles to clear them.
