This edutainment game teaches spelling, math, and problem-solving with four separate games, each with its own mini-games and modes. In Astro-Grover, you do arithmetic with aliens called Zips hovering in the night sky. You count them as they beam from their spaceship or group them with satellite beams, and add and subtract in harder mini-games. When you complete a set of questions correctly, Grover files in and dances.
