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. So, a couple months later, when I finally found it, I bought two copies so I won't have to do without if anything happens to copy #2. I play everyday, and can play it for hours.
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. It also has a button to switch between a full cell or a divided cell to put possible answers in.
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. The "easy" puzzles on Platimum Sudoku are the hardest sudoku puzzles I've ever tried.
Summary: Really fun and encourages addiction. pros - more sudoku games than you can shake a DS at. the mini games are fun, too. cons - no option to turn off the coach. pencil marking is very tiny and hard to read and edit. Only tracks a single player. auto-save is weird, you have to go out to the main menu before the "Saving" message is displayed.
