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.
That missing single unit of payout is exactly where the casino secures its guaranteed profit margin.
The edge is an average calculation over millions of roundsIt cannot be defeated by betting systemsShort-term luck can temporarily overcome the edge
What is RTP in Casino Games?
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.
Which Games Give You the Best Chance?
Smart players actively seek out games where the mathematical advantage of the casino is incredibly thin.
Video poker can also offer an edge below 1%, and sometimes even dips into negative territory with perfect play.
