N number, turn number, and time per turn can be set each game, and statistics can be viewed with the Scores button.

If you accidentally hit the sound or color button during a round, you can hit it again to undo.

See if you can fill up the "Last 100" games graph! Challenge yourself to do higher N numbers, and see how your score correlates to your difficulty with the "Color by N" button!

I hope you enjoy the music!
