Sudoku Gridmaster - Nintendo DS

The stylus feels great for tapping out numbers quickly, and the touchscreen response is spot-on for a puzzle game. I've already burned through a dozen grids this week, and the included case keeps everything neat. Perfect pick for anyone who wants a portable brain workout.

Finally I can take my sudoku obsession on the go—the touch screen makes tapping in numbers feel way faster than pencil and paper. The puzzles start easy but ramp up nicely, and having all those levels in one cartridge is perfect for long commutes.

I’ve been playing a couple of puzzles every night before bed, and the touchscreen input makes number entry feel quick and precise. The cart is in great shape, and the case still has that satisfying click when you snap it shut.
