Casinos are incredibly profitable businesses, and their success relies entirely on cold, hard mathematics.
This guaranteed profit margin is known universally throughout the industry as the "house edge."
True Odds vs. Casino Payouts
If a game paid out at exactly the true odds, the casino would eventually break even and go bankrupt.
That missing single unit of payout is exactly where the casino secures its guaranteed profit margin.

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%.
