Each class of creature is also represented by a counter, and the cards are also used to trigger the movement of the counters along the trails on the boards and by migrating, from one board to another. Breeding, achieved by flipping over a creature's counter, generates new cards. Movement facilitates further breeding and the chance to secure tokens for additional icons and point scoring.
At the end of the game, points are scored through abilities on the creature's cards, the position of the creatures' counters on the boards, and from tokens; the player with the most points wins. Rules for an introductory game for up to three players are included.
