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.
The Secret of the House Edge
Casinos generate their edge simply by withholding a tiny percentage of the true probability payout.
Take European roulette, for example: there are 37 numbers on the wheel, making the true odds 36 to 1.
- Every single game has a mathematically defined edge
- It represents the percentage of each bet the casino keeps
- Skill-based games usually offer lower house edges
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.
However, because of short-term variance, one player might win $10,000 while another loses their entire bankroll.
Finding the Best Casino Odds
If you want to stretch your bankroll and maximize your chances, you must play low-edge games.
Avoiding high-edge games is the easiest and most effective strategy for any casino visitor.
| Game Option | Expected Return | Difficulty |
|---|---|---|
| Video Poker | 99.5%+ | High |
| American Roulette | 94.74% | None |
You cannot defeat the math, but you can choose the games that give you the fairest possible fight.
