Gambling is one of the oldest known pursuits of mankind. Archeological evidence suggests that even the earliest caveman was a gambler. Dice-like objects made from the ankle bone of a sheep or dog called Astragali dating back 40,000 years have been found. Cave drawings depicting gambling offer further proof of the existence of early gamblers. Pairs of dice have even turned up in the ruins of Pompeii, some of them "loaded" to fall a certain way.
