Casinos are incredibly profitable businesses, and their success relies entirely on cold, hard mathematics.
This guaranteed profit margin is known universally throughout the industry as the "house edge."
How Casinos Create the Edge
The house edge is created by paying winning bets at slightly less than the true mathematical odds.
However, if you win a straight-up number bet, the casino only pays you 35 to 1.
The edge guarantees the casino will always make moneyIt is the cost of entertainment for the playerLower edge games preserve your bankroll longer
The Flip Side of the House Edge
RTP is simply the inverse of the house edge, expressed as the percentage of money returned to players.
RTP is a long-term statistical average, not a guarantee for any single gaming session.
Finding the Best Casino Odds
If you want to stretch your bankroll and maximize your chances, you must play low-edge games.
Video poker can also offer an edge below 1%, and sometimes even dips into negative territory with perfect play.
