There are 2 versions: one for black/white (nonobw.prc) (Palm OS 3.0+) and the other one is for color devices (palm OS 3.5 or higher required) (nono256.prc). I've to admit that I wrote using colors and later "stripped it down" to black and white. Someday I'll make it nicer in b/w.
The object of the game is to find out where to put the blocks (=filled rectangle) and where not (=square dot). The numbers on the side of the field stands for the number of connected blocks in a row or collumn.
(forgive the simple use of ascii art...someday...)
Example: 1 1 2 ___ 1| | | Row 1 --- 1| | | Row 2 --- 2| | | Row 3 --- C C o o l l . . 1 2Column 1 has "1 1". That means two blocks of 1 square in vertical. Column 2 has only one block of the size of 2 squares vertical , etc.etc. If all numbers match, the solution has to be:
1 1 2 ___ 1|X| | --- 1| |X| --- 2|x|X| --- X=filled square
It's not so hard to guess this, but if you field is 10x10... To try out solutions, you can use the "Try mode". Just check the checkbox, and every square will be filled with another color/shape to distinguish it with the "real" solution. If you realy, realy, can't find the solution, or you still don't get it what you should do, use the menu option "Solve" to let your palm do the work.
On the topleft corner you'll see the gamenumber. If you can't solve the current puzzle, try another one by tapping the arrows on the sides.
Good luck !
