The Mathematical Advantage of the Casino
We've all heard the phrase "the house has the edge". But what does this actually mean? Grasping the house edge and casino RTP is crucial for anyone who wants to gamble intelligently.

Defining the Casino's Advantage
The house edge is the percentage of a player's original bet that the casino expects to win, on average, over the long term. If the house edge is 2%, the casino's theoretical average earning from $100 in bets is $2. This is a statistical probability over millions of wagers, not a guarantee for any single session.

Understanding RTP
It's the same concept but viewed from the player's side. It represents the percentage of all the wagered money that a specific game will pay back to players over time. A 96% RTP means a 4% house edge (100% - 96% = 4%).

RTP is most commonly used for slot machines, and you can often find this information within the game's help or information screen.

How Games Stack Up
The house edge and RTP can vary significantly from one game to another. Smart players gravitate towards games with a low house edge.

Game Typical House Edge Notes

Blackjack ~0.5% - 2% Requires optimal strategy to get this low edge.

Baccarat ~1.06% (on Banker bet) Always bet on the Banker for the best odds.

European Roulette Exactly 2.7% The one green '0' pocket is the source of the edge.

American Roulette 5.26% The addition of the double zero ("00") pocket nearly doubles the house edge compared to European Roulette.

Slots Varies widely Always check the RTP of a slot before playing.

Playing Smarter
Understanding house edge and casino RTP empowers you to make informed choices. Your goal should be to play games with the lowest possible house edge. This gives you the best statistical chance of walking away a winner and ensures you get the most entertainment value for your money.
