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."
How Casinos Create the Edge
Casinos generate their edge simply by withholding a tiny percentage of the true probability payout.
That missing single unit of payout is exactly where the casino secures its guaranteed profit margin.

What is RTP in Casino Games?
If a slot machine has a 5% house edge, its theoretical RTP is exactly 95%.
RTP is a long-term statistical average, not a guarantee for any single gaming session.
Which Games Give You the Best Chance?
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.
