Each player tries to move his herd of dinosaurs across the finish line first by rolling dice and counting. A player chooses a herd (all Stegasauruses or Dimetrodons or T. Rexes or Triceratops, etc. Each dinosaur in a herd is a different color: red, yellow, green, and purple. A player rolls four dice and puts them in any order he wishes so that they make a four-digit number. Then he moves each dinosaur along a separate colored path: the red dinosaur moves by the thousands digits, the yellow dinosaur moves by the hundreds digits, and so on. Then the next herd of dinosaurs starts their trek on the path to the finish line. Game variations allow for showdowns, "Dino Math Action," and "Prehistoric Problem Solving" for older children.
