Walk into any airport or train station and you’re likely to see someone with a sudoku book. The number-based puzzle game has taken the nation by storm, and now a dedicated sudoku title is coming to the Nintendo DS. Once you’ve played Sudoku Gridmaster, you’ll never go back to pen and paper again.

Features:

• Sudoku Gridmaster uses intuitive touch-screen controls that make solving the puzzles faster and easier than ever. Players simply touch the square they want to fill in, then touch the answer on the number pad. They also can choose to forgo the number pad and write answers directly on the touch screen.
• Sudoku Gridmaster features more than 400 sudoku puzzles, all of which were hand-picked by the sudoku masters at Nikoli - the original creators of sudoku.
