Sichuan is a so-called Nikakudori puzzle game that uses mah-jong tiles.

The target of the game is to clear mah-jong tiles by creating matches within Nikaku, which means two corners. You’ll be able to reach the next level if you clear all the tiles on the board. The game will be over if you cannot create any more pairs, and run into dead end. However you can shuffle the tiles by shaking the iPhone and keep playing until you complete the game. (You can disable the shuffle function from the option menu.)


Find the pair tiles and those tiles are taking in the following case.
Tiles that have no other tiles between them and can be connected within 2 corners of each other (it contains maximum 3 lines).
By clearing all the tiles on the board you’ll complete a stage.
