Summary: Sudoku in a video game should be straight forward, easy to grasp controls, and a font that's pleasant to look at at. Sudoku Gridmaster has all of this. Plus you can test to see where you rank (ie bronze, silver, gold, platinum) after completing a certain number of puzzles in Normal or Hard mode. This version is MUCH better than Platinum Sudoku in my opinion, even though there are only 400 puzzles here. The puzzles are similar to the Nikoli versions .
Summary: I LOVE this game. It's fun and stimulating whether I have 15 minutes or an hour of free time. With a variety of levels of difficulty, it will be a long time before I need to buy another Sudoku game. Well worth the money!!
Summary: This is the most addictive Sudoku DS game that I own (and I have them all). I only wish they would come out with a second edition. Being able to highlight blocks and numbers really helps my playing. I have found that playing Sudoku Gridmaster has honed my overall playing skills. When I go back to Brain Age, I can solve puzzles more easily and efficiently as a result of playing Gridmaster. I can barely put it down.
Summary: I was given a Nintendo DS for Christmas. I'd asked for it to have portable entertainment when travelling. Upon learning that my grandson could beat me badly in action games, I moved to pursuits with more deep thought needed. That'll work for a year or two and then I'd better be well into the "hard" level!
