The advantage that the casino has over players

Why Do Casinos Always Win | Tips For Canadian PlayersYes, the casino will always have a mathematical advantage over the player, but there is one legal way to get an advantage over the casino. This trick uses the help of bonuses given by the gambling site.

Next, we will consider three different types of casino games, and we will find out which one has a better percentage of winning.

Playing Roulette

There are three very popular types of roulette – The European one is the most famous one (with one zero), the American one(two zeros) and the French one (with one zero). You need to know that if the wheel doesn’t have a zero, then there will not be an advantage; the chances will be equal for the player and the casino. So, there will not be a point in this game in the long term; there won’t be a winner in the end.

  • Playing RouletteThe advantage of the European roulette with one zero will take 1/37 of each bet made; this is a 2.7% advantage for the casino on your average bet.
  • The American roulette is the most unprofitable version for players because of the two zeros on the wheel; the percentage is a 5.3% advantage over players.
  • The French roulette also has one zero and is similar to the European one. The only difference here is when the player makes big bets on Red or Black and the ball drops to zero, then half of the lost bet is taken by the casino, and the rest gets left for the next spin. In this case, the advantage of the Canadian online casino over the player is 1.3%.
  • You may see a wheel without a zero, but this will mean that the roulette will scam you, and the casino sets the RTP numbers up.
  • You can play roulette from NetEnt with an RTP of 97.3%, but you need to know that this percentage will be fulfilled in a long game. In a short period, anything can happen.

Why Do Casinos Always Win | Why Can’t I Win Roulette In The Long Term?

Why Can’t I Win Roulette In The Long Term?We will consider the European one because it’s more popular. So, even if you bet on all of the numbers (1 CAD), your final bet will be 37 CAD, the payout will be 36 CAD.

So, even if you win 10 times in a row, in the long term, a day, a week or a month, you will lose all of the money. If you don’t know whether to believe us or not, you can easily check the roulette; just read the article until the end.

Why are strategies useless?

Let’s consider all of the possible bets at roulette and see the final results of the mathematical expectation.

In the picture below, you will be able to see a formula that calculates each separate bet.

how to beat roulette formula, (1)

  • Where is xi– event I,
  • Pi– The probability of event I,
  • К – The total number of events forming a complete group.

European roulette mathematical expectation (ME)

The formula (1) ME, unlike any made bets on “European roulette,” can be converted taking the full probability, not collaborative events, that is Pwin.+ Ploss.=1, to the view of the game in the N sectors (rooms), is equal to:

how to beat roulette formula 2 Why Do Casinos Always Win, (2)

Since the probability of winning Pwin in “European roulette” while you are playing for N sectors (rooms) is equal to

how to beat roulette formula 2.2 so, we finally get ME for any bet at European roulette when you are betting on N sectors (rooms), is equal to:

how to beat roulette formula 3 Why Do Casinos Always Win, (3)
Let’s calculate ME for every single bet in European roulette. Then, the result of ME can be seen in table 1.

The mathematical expectation for the bets

Table 1. Calculation of ME for “simple” bet

«Simple» bet
Straight-Up Payout – 35 Win Probability 1/37 Loss Probability 36/37 =35×1/37-36/37= -1/37
Split Payout – 17:1 Win Probability 2/37 Loss Probability 35/37 =17×2/37-35/37= -1/37
StreetStreet Payout – 11:1 Win Probability 3/37 Loss Probability 34/37 =11×3/37-34/37= -1/37
Corner Payout – 8:1 Win Probability 4/37 Loss Probability 33/37 =8×4/37-33/37= -1/37
Six Line Payout – 5:1 Win Probability 6/37 Loss Probability 31/37 =5×6/37-31/37= -1/37
Column & Dozens Payout – 2:1 Win Probability 12/37 Loss Probability 25/37 =2×12/37-25/37= -1/37
Even Chance Payout – 1:1 Win Probability 18/37 Loss Probability 19/37 =1×18/37-19/37= -1/37

What does the table show? ME is exactly equal to the value obtained by the formula (3). Let’s look at the results. The player will lose at the end, even if he wins

Zero rouletteWhen the punter places a bet (any bet) on the European roulette, he loses 1/37 of the made bets in the end. By the way, the results for American roulette are even worse. That’s why owners of casinos don’t care if the gamblers win 1, 2 or even 10 times in a row.

As long as they return to play, the owners know that they just “borrowed” the won money but with huge interest. So, no matter how many times the player wins, he will return all of the money and will even spend more than he won at the casino. Only 1-2% of the people will succeed in stopping the game on time, and they won’t return the money for a long time.

Using bets strategies

So, no matter what kind of strategy you use, when the ME is -1/37 of each bet, the ME will always be negative for the player in the long term. We should not forget that casinos are made for the owners to become wealthy. That’s why they add restrictions to the maximum bets; thus, the strategies are useless in the long term.

Dispersion

Let’s calculate the volatility (dispersion) of any bets made at roulette depending on how many sectors N (rooms) we bet on. Then, use the variance (dispersion) to determine the optimal Bank Kelly criterion when playing European kind.

Information

Bank on Kelly’s criterion shows what a gambler’s bank to the total balance should look like aspired to infinity.

We can calculate the dispersion of the bets like this:

how to beat roulette formula 4 Why Do Casinos Always Win, (4)

The formula (4) for the variance “D” of any bets can be converted to take the full probability, not joint events, Pwin.+ Ploss.=1, to the mind:

how to beat roulette formula 5 Why Do Casinos Always Win, (5)

Since the probability of winning Pwin while you’re playing in the N sectors (rooms) is equal to:

how to beat roulette formula 2.2, finally, we get the expression for the dispersion” D “of any bet when you are playing in the N sectors (rooms), is:

how to beat roulette formula 6 Why Do Casinos Always Win, (6)

The magnitude of dispersion in”D” has a positive value throughout the range of games in the N sectors. That is an important detail.

Places where you should calculate the required bank for the game at “European roulette” using Kelly’s criterion:

how to beat roulette formula 7, (7)

Using the expressions (3) and (6), we finally obtain the expression:

how to beat roulette formula 8 Why Do Casinos Always Win, (8)

According to Kelly’s criterion for playing, the formula (8) shows that the optimal amount of the bank is a negative value.

Summary

If the optimal value of the gambler’s bank following Kelly’s criterion is negative, then playing roulette isn’t recommended because the balance will always be close to zero. In the long term, he will lose all of his money.

If you want to get the total picture of gambling and how “good” it is to gamble, you can follow Kelly’s criterion for a mathematical expectation of the game result that is:

how to beat roulette formula 9 Why Do Casinos Always Win, (9)

This picture shows that a small bank balance is actually better for players.

The optimal criteria of the Кoptima game can only be used to evaluate games with a positive expectation! If the game has a negative ME, it will not attract the attention of the gamblers. For European roulette, it’s ME -1/37, which is less than zero, so this game is not profitable for the punter. This is the reason why this game is not mathematically good for a player, regardless of the used strategies, tips, bets, etc.; in the end, you will be the one who loses all of the money.

Note: the formula (3), (5) and (8) can be obtained for “American roulette” with two sectors of zero: 0 and 00.

Playing poker

Playing pokerThe card games are the most unprofitable games for players (except Blackjack and partly Baccarat). There is a hidden secret behind shuffling the cards after each hand; the player thinks that he is losing slower; this is kind of true, but he is losing more and for sure. There are a few variants of pokers that are the most popular at Canadian online casinos: Oasis, Six card poker, Russian, Red Dog and others.

  • Oasis poker has an advantage of 5% over the player, depending on the rules implemented by the casino.
  • Six-card poker has a 7% advantage.
  • At Russian poker, you can change the cards without paying additional money, but the advantage of the casino is 9%, which is a huge percentage in my eyes.
  • So, following the statistic, we can conclude that the advantage of the casino when you choose to play poker would be between 5% and 9%, that’s why poker games are very unprofitable for players.
  • Online poker from NetEnt, where you will enjoy an RTP of 98.75%.

Playing slots at online and land-based casinos

The best gamesThere are 2 types of slots: land-based slots and online slots. The percentage of return (RTP) is usually between 80% and 90% in the first variant. This means that a few players have a real chance to hit a huge winning.

Online slots have become more and more popular over the past few years, not only because it’s a convenient way of use but also for the RTP. Right now, the most popular slots come from NetEnt and Microgaming, but many other providers offer a higher RTP.

If you are playing at an honest and reliable Canadian online casino (like Fastpay), you will enjoy an average RTP of 96%, while the blacklisted casinos offer an RTP of 90% – 95%. Play all of your favourite slots for free right here, and get familiar with the return of percentages.

The best games

Blackjack and slots can be extremely profitable for a player. Even if you are not following a specific strategy, you can get a positive expectation of winning.

Slots with high volatility have a higher chance of hitting a big win, but they also have a higher chance of losing the entire balance of the money.

Conclusion

In the end, we have concluded that the most unprofitable game is poker, while the top 2 most profitable games are Blackjack and slots. Try to use strategies when playing at Canadian online casinos, this will increase your chance of winning. Make sure you choose trusted casinos as the blacklisted ones may lower the RTP of the games. Do not forget that one of the essential things when gambling is to stop on time. If you are lucky enough to hit a Huge Win, then we recommend you stop playing immediately, then request cashout and forget about gambling for a while.
