The storyline is a bit predictable but it's the puzzles that are really great (and of course the most important aspect of this game). This game is suitable for both children and adults alike. There are some old well-known puzzles and some new ones. Play time is decent, especially if you get stumped on particular puzzles, and can take up to 15 hours to complete the story mode. I still haven't managed to unlock everything! If you really enjoy brain teasers you'll love this game. It's challenging enough for even the keenest puzzle solvers, and makes a change from the regular set of games we usually see on DS. Five stars!
