Sudoku Gridmaster review:
I never really had any interest in Sudoku until I learned how to solve the puzzles from the tutorials that came with Brain Age. More recently, I would even skip my brain training because I would be playing Sudoku and forget the daily exercises. Needless to say, Sudoku Gridmaster came as a really nice surprise.
It took me a bit to adjust to the controls since I was very comfortable with the ones in Brain Age, but after a few puzzles it wasn't so awkward anymore.
For those (like me until a couple of months ago) who aren't familiar with Sudoku, the rules are fairly simple. You must insert the numbers from 1 to 9 in each of the nine 3x3 squares in the grid, without repeating them in any row or column. By inputting possible answers into each square, you begin an elimination process that leads to finding the correct numbers for each grid cell, until you fill up the grid with all the numbers.
Sudoku Gridmaster lets you use the stylus to either input the numbers in a keypad or by writing them down, although (and opposite of Brain Age) I prefer using the keypad to the writing.
Sudoku Gridmaster review:
Other aids to attaining complete grid mastery are "temporary numbers" -- you can enter up to four small numbers as possibilities in each space -- and the ability to highlight a number to see every instance of that number across the board. When a number is no longer available as a correct answer, it will be darkened on the keyboard.
