The board is built differently according to:
It can be selected as 14*6, 18*8, 24*12, 26*14 or 30*16. (with Setup->size)
Several tile sets are provided.
It can be selected as ôeasyö,ö mediumö or ôHardö. There is no real difference between easy and medium. Hard suppresses most of double adjacent tiles.(with Setup->Level).
When building the game, the program tries to solve the game with one of its internal solvers. I have not yet succeeded to write an acceptable solver. When the game tells you the game is solvable, it is solvable, but when it says it is not solvable, you can most of the times solve it. The only reliable solver I have written may take hours to solve the game recursively, so I avoid using it.
In this mode, tiles are shifted toward the board bottom. Undo and redo can still be used. The mode can only be set before playing.
This combine gravity mode and tile falls. Tile column heights are compared with previous and next column. The biggest difference is used to select the falling tile. If there are several columns with the biggest difference, the one on the left is used.
In this mode, empty vertical or horizontal rows and columns are suppressed.
This make the game more difficult.
To work quietly.
For slow PC
To use if the display doesn¢t flicker when using it. The Asama mount is a volcano near Tokyo.
This setup allows game playing with one finger. (Without using the mouse) Read Keys section
This set the default background. You can load your own bitmaps with the ôFilesö drop down menu ôLoad background bitmapö. Only BMP, JPEG and PNG bitmaps are supported. Loading an unsupported bitmap can gives unpredictable results. Some Old OS/2 bitmaps can be loaded also.
Any tile you remove is added to the undo list.
Any tile you add with the undo option is added to the redo list.
These options are only available when the lists are not empty.
Undo/Redo facility activates the cheat status, but as this usually take more time, this is not accounted for in the final result.
The Demo mode can be used make the game more difficult by starting with a partially solved game. You can stop the demo with the space key. When using the demo mode during a session, the Demo is written down on the high score board.
You can switch between normal windowed view and full screen mode with the F11 key (ESC or F11 to quit).
