Simple roll and move game. Each player has 4 dinosaurs and moves along a track. There is an additional dinosaur, a t-rex, which is moved by everyone. The players roll three dice. They can move the t-rex in any direction, the distance being determined by the black die. The two white dice are used for moving one's own dinosaur(s). The results of the two dice can be added up or used separately.
When the t-rex meets another dinosaur, that dinosaur has to start over. When two other dinosaurs meet, they have a dice battle. Loser goes into a river and can only be re-used later. The first player to get all his/her four dinosaurs into the target area is the winner.
