The game includes a cardboard with 12 areas, 30 counters that figure gorillas, sheets for orders and a dice. Each player secretly chooses one gorilla, and his goal will be to climb to the highest hierarchy level in his group of gorillas. During the game, each player secretly writes orders for specific gorilla(s), which will be resolved simultaneously. These orders relate to natural activities of gorillas; the dice are used to determine the results of some activities, as conflicts.
