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

The house edge is the invisible force that ensures the establishment always makes money over the long haul.

How the House Edge is Calculated

Casinos make their money by paying out slightly less than the true mathematical probability of a win.

If you bet on a single number in roulette, you have a 1 in 37 chance of winning, but the payout is only 35 to 1.

• This slight discrepancy in payouts guarantees that the casino retains a small percentage of all money wagered
• A 2% house edge means the casino expects to keep two dollars out of every one hundred dollars bet
• Over millions of spins, this tiny percentage translates into billions of dollars in guaranteed revenue

The Flip Side of the House Edge

When discussing slot machines, the house edge is usually referred to by its inverse metric: Return to Player (RTP).

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

You cannot defeat the math, but by choosing games with a low edge, you can play much longer for the same price.
