Summary: I love this version of sudoku. I've even bought it three times. It was in my first DS-lite when it got lost during a roadtrip. When I got another DS, I looked for this game everywhere and was having no luck.
Summary: This game often gets compared to Sudoku on Brain Age. Platinum Sudoku certainly has features and bells and whistles that Brain Age does not, but that is not necessarily the best thing. The interface is nice. It has the option to write directly to the grid or punch the number on a keypad.
Summary: I've been doing sudoku puzzles for about three years and have become a fairly good player. I've been able to solve the "hard" puzzles in the Brain Age 2 game and I do nothing now but the hard puzzles on a hand held sudoko game I have.
