Matheroids was the iPhone version of Mathteroids, the Math Asteroid game. The goal of the game is to blast away at the asteroids that float across the screen - but only if they are numbered with a multiple of the goal number! If you shoot asteroids that aren't multiples, a horde of tiny blue asteroids will zoom towards you and tray to crash into you!
From this page, you can play online in your web browser, although you will need to install the Java plugin. Your high scores would be recorded here. Besides the online version, you can get Mathteroids on your PC or Mac here
Alas, the iPhone version is no longer available.
