Egyptians were probably gambling over slaves. Kinda crazy to think how long gambling has been around and what it looked like from the start up til now. People went from fighting in a pit and wagering on the winner, to throwing dice in a casino, picking numbers on a wheel, or playing a slot machine.
Or probably asking for divine intervention?
Anyhow, yeah dice has been with us since the beginning of human race, no doubt about it. Maybe it was not really design for gambling in the beginning, maybe in the later period. And old civilizations such as China and India, the Greeks have their own dice, from knuckle bone of animals to woods.
But I'm more interested on modern games such as slots and roulettes, and good read.
