Played on a 5x5 board, players try to steer their dinosaurs to feed on plants, and avoid the evil T.Rex as well as each other. Card play determines if the dino moves, stays put, or "panics". In case of a panic, the other(!) players simultaneously, secretly determine the dinos movement. Afterwards, the T.Rex is moved in the same way by all players. The 4 dinos have different features, some can fly over the volcano, swim through the lake (both variable board elements), and have different amounts of "panic" cards (which must be played throughout the game). The player who ate the most plants in 8 rounds wins (9 for 3 players).
