Sudoku Mania - Nintendo DS

The touch screen makes it so easy to pencil in candidates and erase mistakes. I'm already hooked on the daily puzzle mode after just a week.

I’ve been playing this on my commute, and the touchscreen makes placing numbers feel super smooth. The difficulty curve is just right—starting easy and getting trickier without being frustrating. Great fun for a quick mental workout.

The stylus controls on the touchscreen make placing numbers feel surprisingly smooth, and the endless grid variations keep me coming back for another round every night. I've already burned through a week's worth of commutes on this.
