Anyone who visits a casino dreams of hitting a massive jackpot. Yet, the reality is that casinos are designed to make money. This profitability is secured through a statistical formula called the casino advantage. To evolve into a wise gambler, it is vital that you understand how odds work before placing any real money wagers.

Defining the Casino Advantage

The casino's advantage is essentially the exact percentage that the casino holds over the player in the long run. For instance, if a game features a 5 percent advantage, it means that theoretically, the casino will keep five dollars for each hundred wagered. This does not mean every session costs 5%, because immediate volatility allows players to secure profits.

Evaluating Winning Chances in Casino Formats

Not all casino games have identical margins. Specific formats are known to have massive casino advantages, while alternative games are much more favorable to the gambler. Activities involving decisions, like classic 21, enable players to reduce the mathematical margin by using basic strategy. On the flip side, pure chance games like many side bets give the casino a massive lead.

• Blackjack offers the best odds if played with basic strategy.


• Choose the single zero wheel due to a lower house margin.


• Skip the bonus bets as they usually carry massive house advantages.


• Jacks or Better can offer over 99% RTP with optimal play.
