I've played sudoku for quite some time now and I find that it's pretty interesting. Not only does it helps to kill time while waiting for your queue number, it also improves your thought processing skills! Who says games are a waste of time? Of course a game's no fun if you can't complete it. But sudoku's different. You can complete it, it's just a matter of time. Sometimes you just need that break before coming back. Then will you realise that "7" should be placed in that corner instead of "3". So go over to Iron Sudoku and join the online community of Sudok-ers.
