sudoku
sudoku's a type of puzzle that's kinda fun. at least it entertains me about as much as the battleship puzzles in games magazine. paint by numbers are better because after doing the work you get to enjoy the picture. in the standard sudoku puzzle you want fill each box, row, and column with the numbers 1 to 9. sometimes they make pretty patterns with the starting numbers. usually they're not very difficult. google sudoku. exercise your mind. go crazy.
