Doctor Eggman and his robots also show up to steal your answer, or in the ring mini-game, to steal all your rings. Sonic the Hedgehog himself is not playable, but acts as the guide instead, you choose from numerous animals as to what you want to play as. You pick up nearby answers (ranging from bouncing letters and numbers to balloons with various pictures on them) to shoot back at a blackboard so as to answer it (usually filling in the blank in the reading section you match up pictures with their words instead), or otherwise recycle (much to Sonic's pleasure).

The entire game plays in a similar fashion to id Software's Wolfenstein 3D, in that you play in a world that has no variation in height and is largely composed of right angles. In addition, players can earn access to two mini-games (a collect-the-rings game and a match-the-statues game) and a 'field trip' section which gives them numerous facts on the various animals in the game.
