Sudoku is a great logic exercise for anyone, but I think it’s an especially good teaching tool for kids. Check out Jigsaw Sudoku. The grids are only 6×6 vs. the regular 9×9 grids you usually see, and you can play online by moving the numbered tiles into the correct spots. You can even get a hint if you need one!

I hadn’t really gotten into the Sudoku craze despite its obvious brain tickler benefits. This may change that.
