Understanding Casino Math And The House Edge

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

Casinos generate their edge simply by withholding a tiny percentage of the true probability payout.


However, if you win a straight-up number bet, the casino only pays you 35 to 1.

Understanding Return to Player (RTP)

RTP is simply the inverse of the house edge, expressed as the percentage of money returned to players.


However, because of short-term variance, one player might win $10,000 while another loses their entire bankroll.

Finding the Best Casino Odds

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.
