Checking this makes the game even harder: If a tile is removed, all tiles lying above it will fall down one step.

If checked, you run the risk of being presented with games that are impossible to solve. Note: Even when not checked, you will fail to complete a game if you remove the tiles in the wrong order!

Use the traditional rules for matching the tiles. Previous version of "KShisen" used to allow only exact tiles matches, which is inconsistent with Mahjongg rules. It is recommended to keep this option checked.

This option changes the rules to the point where it almost becomes a completely different game. When it is active, you can only remove the tiles if they can be connected by a line consiting of only two segments instead of the customary three. However, you are allowed to slide the tiles on the board, if the row or column where they are placed has some empty space. To make a sliding move, you have to click on the tile containing the column or row that can slide, and then on the matching tile. If there are two possible sliding moves, you will have to click on one of the two connecting lines to chose your preferred move.

The slider controls the difficulty of the board from Easy to Hard.

Adjusting this slider alters the speed at which the pieces are removed from the screen after a match has been made.

This slider allows you to can change the number of tiles on the board. The more tiles you have, the harder (and longer) the game will be.
