This is a Ludo-type game for 2-4 players. Each player has 4 dinosaurs and has to get them around the board to the home whilst avoiding a rampaging Tyrannosaurus rex. The winner is the first to get all 4 of their dinosaurs home.

On each turn, a player rolls 3 dice—two white and one black. They first move the Tyrannosaurus forwards or backward in an attempt to catch other players' dinosaurs. If they are caught, they have to go to the "T-Rex Den". Once there, only a 6 can free them. The white dice can be added and one dinosaur moved, or can be used separately to move 2 dinosaurs.

There are shorter and longer stretches of track, and a safe route through the riverbed which the T. rex may not enter.
