Passing time - play Sudoku
Written by silver on March 24th, 2006“Fill in the grid so that every row, every column, and every 3×3 box contains the digits 1 through 9.”
That’s it. No math, just solve the puzzle with reasoning and logic. It may not sound very exciting at first, but try one and you will be hooked!! Sudoku comes in paper and pencil or as a hand held gaming device. It’s a great way to pass time on the plane or while waiting for the train.
