Sudoku is everywhere. Apparently, counting to 9 is more fun than anything a next-gen console could even dream about throwing at us. Just goes to show, amazing graphics are no match for a good puzzle. That’s why arobase has been working on his own version of Sudoku for the PSP programmed in Lua, and now you can play it without having to pay a dime, just extract the downloaded file to LuaPlayer’s “Applications” directory and you can count to your heart’s content!
