Sudoku

Sudoku is a great game for those who enjoy number puzzles, or those who want to become more comfortable working with numbers. You'll need no real math skills to get started, just the ability to count from one to nine. Sudoku puzzles take the form of a large square made up of nine smaller squares. Within each of the nine smaller squares are nine single boxes, in which you'll need to place the numbers one through nine. Once the puzzle is complete, each row and column should have the numbers one to nine and each individual small square should have the same. Easy puzzles will already have lots of the numbers filled in for you, whilst the more difficult ones will have more spaces left blank. Just like chess and poker, it's easy to find sudoku puzzles that you can play online, but unlike the other games, this puzzle is easy to find in magazines and newspapers too. This makes it perfect for busy commuters who fancy challenging themselves to something a little different from the daily crossword.
