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.


How Casinos Create the Edge


If a game paid out at exactly the true odds, the casino would eventually break even and go bankrupt.


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 money
  • It is the cost of entertainment for the player
  • Lower edge games preserve your bankroll longer

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.


Games with the Lowest House Edge


Smart players actively seek out games where the mathematical advantage of the casino is incredibly thin.


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