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.
The history of gambling has not stopped in our time and gambling will continue to change. Those gambling options familiar to us that can be seen in any online casino are likely to become obsolete and will seem wild to posterity, as bets on the winner of battles in the pit look to us now. Although in general, the general concept remains unchanged. If in the past bets were made on the winner in the fighting pit, and for some time on the sports ring or playground, now the trend is shifting towards betting on the winner in eSports computer games.
Gambling will keep on evolving throughout the years up until we won't be around anymore to see what will be the changes and improvement because gambling activities will always adjust on the time and the kind of life in the future just like how it evolved from wagering from a deadly match into just picking digits in roulettes. And the things we used to bet now will be a part in the history soon that the people in the future will think what is it like to play roulettes and basic card games.
