Su Doku Listening 

I played Sudo-San, an accessible Su Doku game, tonight. I was wrong about being able to do a sudoku sitting still. I need to move the mouse around.

As well as displaying the puzzle on screen, Sudo-San allows you to listen to the numbers and you have to play via the keyboard. My mind is boggling at the thought of listening to each row, column and square before working out where to place a number.

Leonhard Euler, a Swiss mathematician, devised an early version of Su Doku called Latin Squares. Euler lost his sight in his thirties and was blind when he invented the puzzle. I'm not feeling any smarter.
