As the name suggests, SudokuZen is based on the numbers puzzle game. <br><br>Most people probably don't remember it, but this is EvilDooinz' second Sudoku homebrew game, the first one being PSP Sudoku that was released more than a year ago (ahh, the nostalgia). The developer's second Sudoku game project sports a different look and comes in two flavors: one for firmware 1.50 and another for custom firmware 3.xx.<br><br>Anyway, check out the download below and tell us what you think about it. Enjoy!
