Understanding House Edge

How to use the house edge to your advantage

All casino games have an inherent edge that favors the casino. It's called the House Edge, and in this guide, we'll explain everything you need to know to overcome it.

Definition of a House Edge

The house edge is also known as the casino advantage. This feature is available on all table games, lottery games, and slot machines in brick-and-mortar and virtual casinos alike. Unbeknownst to many, it also reveals which games provide the best profits for players.

The house edge is built into the games and not set by the casino itself. So, it doesn’t matter how cautiously you play, the house always has an advantage.

How to Calculate the House Edge for Casino Games

The house edge is usually a small percentage, ranging from 1% to 16%, and varies with every game or bet type. For example, let’s look at the red/black bets in a European roulette game.

European roulette has 37 pockets, out of which 18 are black, 18 are red, and the 0 pocket is neither. So, the probability of getting a black or a red is 18/37, which equals 0.4865. 

The casino has an upper hand because of the extra 0 pocket. So, the probability of getting a win is 19/37, totaling 0.5135. Next, you subtract both figures, which is 0.5135 – 0.4865 = 0.027. Multiply this answer by 100 to turn it into a percentage, and you have 2.7% – which is the house edge on a red/black bet.

From the illustration above, the higher the house edge, the lesser your profits from the casino in the long run. That’s why playing casino games with the lowest house edge is important. These games and the casino advantage are listed in the table below.

Blackjack depends partly on a player’s understanding of how to win and the cards dealt. Both online and land-based casinos in the United States offer different versions of the classic blackjack game.

If you use the standard rules and basic strategy, it has a house edge of 0.5%. However, the number of decks used and any rule of the game variations affect the blackjack house edge. 

Lowering the House Edge in Blackjack

Blackjack is one of the best house edge casino games because of its low casino advantage. However, you can lower this advantage further by employing a few strategies. 

One of these is memorizing blackjack charts to tell the possible outcomes of every card you hold. You could also try composite blackjack strategies, which involve using the values of the cards that have been dealt to determine the value of the cards that are left.


The roulette house edge depends on which variant you’re playing. American roulette has the worst odds, beginning with a 5.26% house edge. European and French versions are better as the casino advantage is reduced to 2.7%.

Online casinos have different poker variants, but the one with the lowest casino advantage is three-card poker. Although the house advantage varies based on how you decide to play your cards, it is still better than most variations. 

Lowering the House Edge in Poker 

In poker, you can use strategies like the Martingale system, where you increase your bet with every loss. However, remember that this is a game of luck, and there’s no way to tell what your cards are. So, your best bet is learning more about the game before wagering real cash. 


Baccarat is one of the casino games with the lowest house edge, though this depends on your bet. The banker has a house advantage of 1.01%, while the player’s hand is 1.29% when the game is played with one deck of cards. The tie bet has a huge casino advantage of 15.75%.

One of the best house edge-lowering strategies in baccarat is to avoid the tie bet. Though the payout is higher, the risk is also higher, making it a less desirable option.

Other tips to boost your chances of winning are betting on the banker and playing games with fewer card decks.
