Casinos are incredibly profitable businesses, and their success relies entirely on cold, hard mathematics.

The house edge is the built-in mathematical advantage that the casino holds over the player in every game.
True Odds vs. Casino Payouts
The house edge is created by paying winning bets at slightly less than the true mathematical odds.

Take European roulette, for example: there are 37 numbers on the wheel, making the true odds 36 to 1.
The edge is an average calculation over millions of roundsIt cannot be defeated by betting systemsShort-term luck can temporarily overcome the edge Understanding Return to Player (RTP)
RTP is simply the inverse of the house edge, expressed as the percentage of money returned to players.

This means that over millions of spins, the machine will pay back $95 for every $100 wagered.
Games with the Lowest House Edge
If you want to stretch your bankroll and maximize your chances, you must play low-edge games.

Avoiding high-edge games is the easiest and most effective strategy for any casino visitor.
