This site is all about the famous number puzzle, and you’ll be able to get your fill here whether you’re able to devote some time to the game or just want to jump in and play for a few minutes. You can get a new puzzle delivered to you on a daily basis through RSS, and the Daily Challenge will put you up against other players. However, if you’re like me, then the QuickGame will prove to be a more fitting option. Complete Sudoku neophytes can learn the rules in just a minute or two and use the in-game help to get them started.
