Summary: I guess I was hoping that the Sudoku Gridmaster would compare to the Sudoku game that comes with the Brian Age game. Gridmaster is challenging but if you need reading glasses you had better put them on because you will need them to see the small numbers.

Summary: The game works like the puzzle, enter the numbers between 1 and 9 in all the squares in the grid while ensuring no one number appears in the same row or column twice. If you've played Sudoku in Brain Age, be warned that the two are different in how you use the controls.
Summary: I agree fully with review by "Lego Kid-within" on the User Interface. Having to erase prior guesses is annoying. Even more frustrating is that the game does not allow more than one user to save their game at a time (even Brain Age allows four different user names).
Summary: Riding on the Sudoku wave of popularity, I was eagerly waiting for this product to hit the shelves. Sorry to say, but I think it's a wipe-out. The puzzles are fine, and I like the high-lighted elements when you tap and double-tap the cells, but I found the handwritten input to be too unreliable.
