Just Sudoku!

Sudoku
is a logic-based placement puzzle. The aim of the puzzle is to use every number from 1 to 9 without repeating that number in any column across, row down or within any 3x3 block. There is no math involved - no need to count or add up. Completing the puzzle requires only patience and logical ability. Although the puzzle was first published in a U.S. magazine in 1979, it initially caught on in Japan in 1986 and attained international popularity in 2005. It gives your mind a peaceful yet challenging exercise and you will soon get addicted to it.
