Well I have created a Su Do Ku Generator that works on the PSP 2.0. The 1.5 Realease is more like the one you get in the newspaper. It is sometimes easy and it is sometimes hard.
How To Play Su Do Ku:
Fill in the grid so that every row,
every column, and every 3x3 box
contains the digits 1 through 9.
How to Install on PSP:
Unzip Sudoku.zip onto the desktop.
Place sudoku.html into the root directory of the PSP ( usually F: or G: )
Go to the Webbrowser and type in the adress bar file:/sudoku.html
