The Built-In Advantage of the Casino
You've likely heard the saying that the house always comes out on top. It's a direct reference to the house edge, the mathematical advantage that ensures casino profitability. It represents the average percentage of a player's bet that the casino expects to keep over the long run. For any serious player, an understanding of the house edge is non-negotiable.
The Math Behind the Advantage
The edge comes from the gap between a bet's actual probability and the payout the casino gives for a winning bet. Let's use a simple example from Roulette:
The wheel has 37 numbers in total.
The actual probability of your number coming up is 1/37.
But, the payout for a winning single-number bet is 35:1.
The casino profits from this statistical difference.
The mathematical result is a house advantage of 2.7%.
