The Concept of the House Advantage
The phrase "the house always wins" is more than just a catchy saying; it's a mathematical certainty. It's crucial to understand that this edge does not ensure the casino will win every single bet. This certainty is built upon a concept known as the "house edge" or "house advantage." The house edge is the inherent mathematical advantage that a casino has in every single game it offers. It's a percentage representing the average profit the casino makes from a player's bet over the long term. However, over millions of bets from thousands of players, the statistical advantage guarantees the casino's profitability. Players can and do win in the short term.

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

Early online casinos were simple by today's standards, often featuring a limited selection of games with simple graphics. No longer did a player need to travel to Las Vegas or Monte Carlo. This accessibility was the primary driver of the industry's first wave of growth. However, they offered one thing that land-based casinos could not: unprecedented convenience.

An RTP of 96% means that, over millions of spins, the machine is designed to pay back 96% of the money wagered on it.
