The game features identical 8-card hands, each card showing a number of spaces that must be moved - but it is the total number, adding all the cards played that hand, which determines just how far ALL the cave people will run. Some have modifiers to slow down or speed up your cave person alone - and quickly getting out of sync with the others is how you will survive and send them over the edge. Getting two spaces from the edge is how you will earn Mammoth Meat as the wooly beasts plunge to the valley below - and it take six Meat tokens to win. BUT to refill your hand, you must eat a Meat, in a lovely balancing act.
Your two-piece modular board becomes elongated after every successful hunt, changing the conditions and lengths individual players have to go to score a Mammoth.
Of course, the other way to win is to eliminate all four of your opponents' tribespeople by forcing them into tar pits, crushing them under CHARGING mammoths, or sending them flying over the cliff. It's a think, double-think, guts game of prehistoric survival!
