As if any of us needed another way to kill time on the net, but I'm going to give you one more anyway.
Sudoku, courtesy of me. This game is super fun, super addictive, and takes super reasoning ability. Why am I using the word 'super' so much? Because the game is super popular among the Japanese.
Give it a try. If you need more directions than the brief ones I've listed on the page, google them or leave me a comment.
Think it's easy?? Well, do ya' punk?
