Oh no, the Spinosaurus attacks! It's your mission to help the Colby brothers, who want to safe the other, peace-loving dinosaurs and bring them to their shelter. And don't forget to rescue the Colby brothers, too. The final task to win, is to put the safety fence into action. Players act in a cooperative way to achieve this, all together win or lose. The game is driven by dice rolling mechanics. Depending on the dice roll, you have to move either the Spinosaurus or one of the Colby brothers. Each of the brothers has to move once, before they may move again. On their way back and forth they collect Dinosaurs and put them into their trailer, bringing them to the shelter. The Spinosaurus always moves towards the shelter. If the Spinosaurus reaches the shelter before this, you fail.
