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.

That missing single unit of payout is exactly where the casino secures its guaranteed profit margin.

If a slot machine has a 5% house edge, its theoretical RTP is exactly 95%.

This means that over millions of spins, the machine will pay back $95 for every $100 wagered.
Finding the Best Casino Odds
Blackjack, when played with perfect basic strategy, offers a house edge of roughly 0.5%.

Video poker can also offer an edge below 1%, and sometimes even dips into negative territory with perfect play.
