Tweet

Banish boredome! While queuing for cab or waiting for your always-late friends.Soduko samurai is a perfect time-filler.You'll be surprised at how a number puzzle can be extremely addicting,specially when there's no math involved. Just fill in all boxes with numbers 1-9,However,each number can only be used once in every box(3x3),column(up and down) and row(across).Wanna try playing this too?Well..Goodluck!
