This guaranteed profit margin is known universally throughout the industry as the "house edge."
How Casinos Create the 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.
The edge guarantees the casino will always make moneyIt is the cost of entertainment for the playerLower edge games preserve your bankroll longer
The Flip Side of the House Edge
While table game players talk about house edge, slot machine players focus on Return to Player (RTP).
RTP is a long-term statistical average, not a guarantee for any single gaming session.
Finding the Best Casino Odds
Blackjack, when played with perfect basic strategy, offers a house edge of roughly 0.5%.
Conversely, games like Keno or the Tie bet in Baccarat feature massive edges exceeding 14%.
