Chapter 2. Playing KShisen

Rules

The aim of the game is to remove all tiles from the board. Only two matching tiles can be removed at a time. Two tiles can only be removed if they can be connected with a maximum of three connected lines. Lines can be horizontal or vertical, but not diagonal.

You don't have to draw the lines by yourself, the game does this for you. Just mark two matching tiles on the board, if they can be connected with a maximum of three lines, the lines will be drawn and the tiles are removed.

Remember that lines only may cross the empty border. If you are stuck, you can use the Hint feature to find two tiles which may be removed. Clicking a tile with the right mouse button will show you all corresponding tiles, no matter if they are removable at the moment or not.

The game is over if no moves are possible and some tiles are left on the board (this should not happen if the option Disallow Unsolvable Games in the Settings menu is checked, since for these games there is at least one way to solve it, though it may happen that you choose the wrong way).

The resulting score “S” is calculated using the following formula, assuming that “n” represents the number of tiles present when the game started and “t” standing for the time (in seconds) it took to clear the field:


S=(n/t)*sqrt(n/84)/0.0014

If you played with the Gravity setting enabled, this score will additionally get multiplied by two.
