The Built-In Advantage of the Casino
The old adage "the house always wins" is well-known for a reason. This saying describes the house edge, the core principle upon which all casinos operate. 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 casino a winning bet. Roulette provides a very clear illustration.
A European Roulette wheel has 37 pockets (numbers 1-36, plus a single 0).
The actual probability of your number coming up is 1/37.
However, if you do win, the casino pays you out at 35 to 1, not 36 to 1.
This discrepancy between true odds (36:1) and payout odds (35:1) is the house edge.
In this case, the house edge is 2.7%. This means that for every $100 bet on the wheel over a long period, the casino expects to make an average profit of $2.70.
Which Games Offer the Best Odds?

Craps (Pass/Don't Pass) Around 1.4% The game offers some great bets and some terrible ones.
European Roulette Exactly 2.70% A fixed edge that applies to almost every bet on the table. Consistent and predictable.
American Roulette 5.26% This is a clear example of how a small rule change can dramatically affect the odds.
Slots Usually 4% to 8% The edge on slots is generally higher than on table games.
