"Prehistory.
Hot. Primordial. Dull.
You've been dominating the earth for longer than you can remember.
Then again, with a brain the size of a walnut, you've also been standing there for longer than you can remember.
Nevertheless, you're completely positive that it's been ten million years since anything interesting has happened.
So you decide to cajole your buddies into a suicide race across skull island. The winner is the first to hurl himself into a big volcano in the middle. The losers are everyone who got their hedz bitten off along the way."
A very simple race game: throw your dice and move your dino. The track is rather long though and when parts of the track pass close to another part, players may throw rocks at each other which place you back at the start.
