Description from the publisher: Croopo is a fun, strategic, two-person trading card game where players battle each other by carefully choosing Creature, Power-up, and Terrain cards, and rolling dice to determine the outcome of each turn. Croopo can be enjoyed by kids as young as six years old, and by adults of all ages. For younger kids, rules may be modified for simplification, for example, by omitting Terrain or Power-up cards from the deck. Each game takes around 30 minutes. All you need to play Croopo are two decks of cards (one for each player) and two six-sided dice. A game board is also available to help beginners place cards correctly. Players can build custom decks by choosing different combinations of cards from their collection in order to develop new strategies of game play.
