Calculation of Casino House Edge
The house edge (HE) is defined as the casino profit expressed as a percentage of the player's original bet.
For American roulette, the house edge is higher at 5.26%, due to the game featuring an additional zero pocket, while failing to account for that in the paytable. Roulette Bets There are numerous different bets that you can place while playing roulette and each comes with its own specific name and payout. In American roulette, the house edge is 5.26%, nearly double that of the European version. This is because the American roulette wheel has the ‘0’ pocket and the ‘00’ pocket, meaning that the house has an even greater advantage when you bet, especially on even money bets. Most roulette tables in the U.S. Have a zero and double zero. Those games have a house advantage of 5.2%. Not the worst game in a casino, but fairly hefty when compared to games like blackjack and baccarat. Occasionally, you can find a European roulette table, with just a zero, and the house edge dips down to 2.7%.
The player's disadvantage is a result of the casino not paying winning wagers according to the game's 'true odds,' which are the payouts expected considering the odds of a wager either winning or losing.
The house edge of casino games vary greatly with the game. House edges for slot machines and Keno may be up to 15% and 25% respectively.
In games which have a skill element, such as Blackjack or Spanish 21, the house edge is defined as the house advantage from optimal play (without the use of advanced techniques such as card counting), on the first hand of the shoe (container holding the cards).
The set of the optimal plays for all possible hands is known as 'basic strategy' and is highly dependent on the specific rules, and even the number of decks used. Good Blackjack and Spanish 21 games have house edges below 0.5%.
Example #1:
Calculate the house edge for American Roulette, which contains two zeros and 36 non-zero numbers (18 red and 18 black).
Solution #1:If a player bets $1 on red, his/her chances of winning $1 is 18/38 since 18 red numbers exist out of 38. However, his/her chance of losing $1 (i.e., winning

−$1) is 20/38. Therefore, the expected value may be calculted as follows:Expected Value = (1)(18/38) + (−1)(20/38)
Expected Value = 18/38 − 20/38
Expected Value = −
2/38 = − 1/19
Expected Value = −5.26%
Therefore, the house edge is 5.26%.
Example #2:
Calculate the house edge for European Roulette, which contain a single zero and 36 non-zero numbers (18 red and 18 black).
If a player bets $1 on red, his/her chances of winning $1 is 18/37 since 18 red numbers exist out of 37. However, his/her chance of losing $1 (i.e., winning −$1) is 19/37. Therefore, the expected value may be calculted as follows:
Expected Value = (1)(18/37) + (−1)(19/37)
Expected Value = 18/37 −
19/37Expected Value = −1/37
Expected Value = −2.7%
Therefore, the house edge is 2.7%.
Example #3:
Calculate the house edge for a game played by wagering on a number from the roll of a single die with a payout of four times the amount wagered for a winning number.
Since the probability of a winning number for a single roll of a die is 1/6, it follows the game has 5 to 1 odds. However, with a payout of only four times the amount wagered (i.e., 4 to 1) for a winning number, the house edge may be calculated as follows:
House Edge = (true odds − payout odds) / (true odds + 1)
House Edge = (5 − 4)/(5 + 1)
House Edge = 1/6
House Edge ≈ 16.67%

How the roulette house edge can help customers by choosing the right game
There are three main types of roulette. The US wheel, the European wheel and the French roulette. Each roulette game has its own house edge. The house edge of the US wheel is 5,26%, for European roulette the house edge is 2,7% and the French roulette uses a house edge of 1,35% but this is even bets only. the extra ‘Double Zero’ on the US wheel makes an outsized difference, almost doubling the casino house edge. All even money and 1/3rd bets lose when either zero is hit, which is a bigger disadvantage to players. This is what drives the ‘golden rule’ or Roulette games. Customers should forget patriotism, and always choose the European wheel when they have the chance! French roulette has an even lower house edge. This is due to an additional rule known as ‘Le Partage’. This returns half of the stake of even money bets when the zero slot is hit. This format is less common online. The very low house edge in this format means that many casinos exclude this game from bonus play-though requirements.

How to reduce house edges with bonuses and comps?
House Advantage American Roulette Games
Players can significantly reduce the house edge of an online roulette game with the use of bonuses and comp point schemes. With so many casinos competing for a persons business, there is no reason to stay with one that does not offer ongoing deals and promotions to keep the bankroll of a player topped up. There are two things to look for when comparing how much bonuses will help customers to reduce casinos’ advantage. First is the play-through or wager-through requirement. This shows how many times a customer needs to bet its bonus amount before the bonus cash can be withdrawn. Next is the percentage contribution that each live game makes towards this play through. Typically, slots are 100%, many table games are 25% and Roulette is between 10% and 20%. French Roulette is often excluded all together.
