Key Factors Affecting the Edge


Blackjack
0.5% - 2%
Player skill and strategy are paramount. "Proposition" bets can have an edge of over 16%. A 95% RTP means a 5% house edge.

Return to Player (RTP): This is simply the other side of the house edge. If a game has a 4% house edge, its RTP is 96%. This means that, over a very long period, the game is programmed to return 96% of all wagered money to players. A high-volatility game (like many progressive jackpot slots) pays out infrequently, but the wins can be massive. Understanding the interplay between the house edge, RTP, and volatility allows a player to choose a game that aligns with their goals and risk tolerance. Players can lose their bankroll quickly on these games, but they also have a chance at a life-changing score. A player looking for a long, steady session should choose a low-edge, low-volatility game like Blackjack or Baccarat. It allows for longer play sessions but offers smaller jackpots. - Volatility/Variance: This describes how a game pays out.

If a casino paid out $1 for every $1 bet on a correct guess, it would have no edge. But if it only paid out $0.95 for every $1 bet, that 5-cent difference would be its edge. For example, in a coin toss, the true odds of heads are 1-to-1. Every casino game is designed with a similar, albeit more complex, mathematical imbalance that favors the house. The house edge is derived from the gap between the true odds of an outcome and the payout odds offered by the casino.
