Essentially, this 2D sidescroller takes you through 12 levels in four environments. After you use two buttons and a D-pad for some gameplay, you're stopped to solve some basic math problems in order to progress. The math problems are fun and focus on simple geometry, fractions, and place values concepts. By connecting the Didj online, parents can choose what part of the math curriculum the game will feature.

Yes, the math problems are presented in an engaging format and appear periodically within the game. And yes, though the game is short, there is a replayability element. If you go back and replay some tasks, you'll earn badges. These badges translate to Bitz points, the faux currency which allows you to trade on the Didj web site (Leapfrog Connect) for sounds and music to customize your game. Too bad you can't exchange them for an extra level or two. The amount of gameplay, although educational, is less than the amount you get in a $10 downloadable game and not as challenging. While the game shows some promise for the Didj, there really needs to be a lot more play and a lot more learning.
