How are the RTP and the house edge calculated in roulette?

As I have already mentioned, roulette is a relatively simple game, so it is quite easy to calculate the RTP and the house edge. In this part of the article, I will explain why the casino always has an advantage in roulette, since it is something mathematically related to the operation of this game and its odds.

To do the calculations, I will use European 96Ace online casino roulette without special rules. However, these same calculations can be used for other types of roulette, with some changes that make this game more or less advantageous for the casino.

You could go ahead and do calculations like these for every possible bet of European roulette, but it is not necessary. Roulette bet payouts are calculated using the same formula, which means that each European roulette bet has the same RTP of 97.3% (statistically, the player wins $ 0.973 for every $ 1 wagered).

In the case of American roulette, the calculations are very similar. All you have to do is replace each number “37” in your calculations with “38” since there are 38 possible outcomes in a double zero roulette game.

All results are less likely to occur in American roulette than in European roulette (other than “00”, which does not exist on the roulette wheel of zero), while the payouts are the same. This is precisely why American roulette has a worse RTP of 94.74%.

Furthermore, American roulette has a bet with an even worse RTP (92.1%). This is due to the non-standard odds of winning (5/38) and the payouts (bet x7) of the “top line” bet. The calculation of the RTP for this bet is: Expected value (bet on the top line of $ 1) = $ 7 * (5/38) = 35/38 = 0.921.

The house margin can be easily calculated using RTP as follows:

House margin = 1 – RTP


Roulette is not the most likely to win a casino game, nor is it the most exciting. However, many believe it to be the classiest board game out there, making it a great experience.

In addition, roulette has very simple rules and offers fairly good odds to the player. It can be played even without knowing the mechanics of the game, although I think it is always good to do a little research and study to understand the basic operation and make good decisions.

So I decided to write this article. I hope you found it useful and I wish you good luck at the roulette tables if you decide to try your luck with this game.

Odds and Winning Percentage

There are so many variations of slots today that knowing what your odds are is practically impossible. Instead, the odds of the slots are expressed as percentages of profit. As a player, you’ll want to search for games that give you the highest percentage you can find, and online that should be 99% or more.

It is rumored that physical casinos even have slot games that pay more than 100%. Casinos supposedly place these games in important areas, so that more people can see when someone wins a grand prize. This does not happen online, but the average profit 12 joker casino online is higher than the average you will find in any casino.

For a 5-cent slot game, the average winning percentage in a physical casino is 92.5%. The 25-cent machines pay an average of 94.1%, the dollar machines 95.9%, and the $ 5 machines reach 98.4%. On the Internet, maintenance costs are much lower than in a physical casino, so the percentages can be higher without the house worrying.

On the Internet, most slot games have an average win rate of around 99%. With so many casinos to choose from, if you like slots, you will have to take the time to find the casinos with the highest winning percentages. It may not make much of a difference during a session, but the more you play the game, the more it will become a significant amount.


Jackpots can increase the winning percentage of slot games because the jackpot amount greatly increases the potential profit. If the jackpot is large enough, the payout of a game can easily exceed 100% of the investment, giving players a positive bet situation.

Just remember that when it comes to jackpots, the higher they are, the better the winning percentage. Only maximum bets will qualify for the jackpot, and if you don’t place the maximum bet, your winning percentage drops dramatically.

Fund Management

When it comes to numbers and odds in slot games, fund management is important. These calculations are very easy to learn. You just have to start by calculating how much money you have to spend on the slots. Once you know how much cash you have to spend, you can break that down into gaming sessions. How often you play a session will depend on each player.

It is important for players to understand that playing online slots is about being able to stay in the game as long as possible, and playing it at the correct betting levels will ensure that you can stay long enough to have a good chance of getting an important award. All slot games make your funds decrease gradually until the time of payment arrives, so playing games where the risks are very high will make you lose your funds before that great opportunity presents itself.

Each slot game will make your funds dissimulate at a different rate. It is expected to lose faster in slot games that have a higher payout potential. When the profit potential is lower, as, in many three-reel games, the loss rate will be slower, it is advisable to balance the bets with the loss rate to make sure you have enough money to be able to play all the planned sessions without ending up bankrupt.

On average, in a 90% payout slot game where a player is taking ten spins per minute, a player will need to pay $ 9 an hour on a 5-cent machine, $ 45 an hour on a 25-cent machine $ 180 on a machine dollar, and $ 900 an hour on a $ 5. Online payout percentages are above 90%, but it is usually faster to play online, so these numbers should serve as an appropriate guide.

The most common fund management strategy mistake that players often make is that they don’t stop playing when they are ahead. A predetermined figure needs to be decided, and the player should exit the game if his funds meet or exceed it after a spin that represents a major victory. Leaving the game at the right time is essential to a successful session.

One of the worst things that many players do after a major win is to keep playing just to round off their credit. Don’t throw your money in the trash just to get a round figure. Some players will get rid of a hefty sum just to play a little more in games.
