This collectible/educational game consists of various plastic miniatures, each with a battle card. There is a starter pack which contains 10 miniatures and 10 cards, and various two- and four-creature expansion packs. Creatures fall into one of four categories: Fire, Earth, Water, or Space. Each miniatures has a secret number printed on the bottom - different copies of the same miniature will have different numbers - thus making it a "collectible" game. There are three different levels of play, for various ages ranges, but all involve a little math, making it "educational".
