The cave has to be huge; most of the dinosaurs were too big to hang around in small casino and so the big cave was so popular. The table were huge also and the dealers were well dressed, instead of money the dinosaurs brought with them different meat, the cheap ones like fishes for the small bets and the worthy ones like zebras for the big bets.

Dinosaurs got addicted to gambling too, many times the gambler was out of any meat and owes the casino more meat that he can handle, and in that case the guards usually killed the gambler and took his meat to cover the debt.

Many people wondering why there are no evidences to those casinos, but actually there are, archeologists just mistaken it to be temples and different houses of humans.

Some experts also believe that the casinos were the reason for the destruction of the dinosaurs. Because meat started to be so rare dinosaurs with no meat left in the casino were killed by the guards and their meat was served to the other gamblers encourage them to stay and gamble some more. The dinosaurs just ate themselves to death. Tried to cover debts and finished with their own arms the era. Let's just hope casinos will not destruct the human kind.
