IGN writes: "I've played some truly terrible Sudoku DS games, and I've played some good ones. This one is a good one. It benefits by being the first one to market as a downloadable version, too – having the game "at the ready" as an executable in your DSi system without the need for cartridge swapping is a really nice thing indeed. It's hard to get excited about Sudoku nowadays, but that doesn't mean it's not a recommended experience. For a pick-up-and-play experience, Sudoku Master's a solid DSi addition".
