We bought this game for my daughter along with the Didj system for xmas. She likes that you can play this game as anyone of the Nickelodeon characters but prefers the game that came with the Didj system over this one.
As far as the educational factor goes, you basically have to solve a math problem before going to each new level. I have not noticed much math during the actual game play.
Overall, it's still a fun game and I would recommend it if your child is a Nick toons fan.
The future of the earth lies in peril as Invader ZIM once again prepares to unleash one of his nefarious plots to take over the planet. This time, he's readied an army of robotic clones. Kids must assume the role of SpongeBob, Danny Phantom or El Tigre to send Invader ZIM packing once and for all. Nicktoon: Android Invasion features four popular characters from Nickelodeon animated shows in an action-packed side-scrolling adventure. As children fight as their favorite characters to repulse the dastardly Invader ZIM, they'll rely not only on the characters' special powers but also their own powers of mathematical computation. With the forces of addition, subtraction and more at their command, children will be well equipped to defeat Invader ZIM's android army and save the planet from ruin.
