Every single game on a casino floor is meticulously designed with a built-in mathematical advantage for the operator.

This mathematical advantage is universally known as the 'house edge,' and it is the secret to their massive profits.

The Math Behind the Advantage

The edge is essentially the difference between the true odds of an event happening and the actual payout you receive.

The presence of the green zero on the roulette wheel is what creates the house edge on all even-money bets.

• Every game has a different edge, meaning some games drain your bankroll much faster than others
• The edge represents the average loss over thousands of hours of play, not a single short session
• Casinos do not need you to lose every bet; they just need you to keep playing

The Flip Side of the House Edge

RTP and house edge are two sides of the exact same mathematical coin.

An RTP of 95% indicates that the machine is programmed to pay back $95 for every $100 wagered over its lifetime.

Ultimately, treating the house edge as the 'price of admission' for your entertainment is the healthiest mindset.
