At the end of the day, whether this game will really improve your brain is not for VideoGamer to say, and the claims on the box that it can help you out when you're feeling 'tired and overworked' are, to their mind, a tad dubious. But if looked at purely for entertainment value, the ten games on offer do give some good, non-violent, simple fun, even if a few of them are practically impossible to beat.
The Compatibility and Multiplayer modes add to the fun too, with some of the puzzles lending themselves rather well to group gaming. Will it improve your brain? Who knows, but it's certainly better than sitting in front of the TV all the time, and at least you don't have to relearn how to write just to be able to play it!
