Underneath the twinkling lights and free drinks, casinos stand on a bedrock of mathematics, engineered to slowly bleed their patrons of cash. For years mathematically inclined minds have tried to turn the tables using their knowledge of probability and game theory, but the best way to beat a casino is to avoid gambling altogether.

Casinos offer their players a variety of incentives to gamble, with welcome bonuses being the most prominent example. These can manifest themselves as extra funds credited to a player’s account or as casino free spins on popular slot games. In either case, they serve as a warm welcome and help players get accustomed to the online casino world’s atmosphere.

The house edge of casino games is the statistical probability that a casino will retain, on average, from each bet placed by patrons. This percentage varies between casino games and is determined by the mathematicians who specialize in this field. These professionals are known as gaming mathematicians and gaming analysts.

Gambling, in its various forms, has been around for thousands of years. The precise origin is unknown, but it is widely accepted that gambling in some form was present in every culture throughout history. It is now commonplace in most countries and is a major source of income for many nations and governments.
