One of the essential pieces of advice that any professional can give you is that it is crucial to know the game from A to Z. This information undoubtedly includes your chances of winning and the overall advantage of the casino in the game, and all her bets. We have picked bets and games with the highest mathematical edge.

Individual Bets with the Highest Probability of Winning

First of all, let's look solely at the probability of winning individual bets. However, we will not take into consideration the combined bets in roulette, where the entire playing field can be covered. In that case, "Win" is guaranteed. What is certain, however, is that your bankroll with such bets will not change in any way.

We will stay with the mentioned roulette and focus on its even bets, which at first sight seem to be a clear favourite. Colour, even x odd or high, low bets offer almost a 50% chance of winning, which is the maximum we can hope for. At least on roulette.

Chances of winning on even bets at roulette

• American - 47.37%
• European - 48.65%

These are very nice numbers. However, there is an even better bet! Specifically, we find it at the craps table, where the chances of winning a Pass bet is 49.29%. This bet also offers one of the smallest house edge - 1.4%.

Technically speaking, you can find a bet where you have a probability of winning precisely 50 to 50. Some slots offer a gamble function, where you have the option to double your win by guessing, for example, one of two colours. Interestingly, although the gamble function is one of the most advantageous bets, it does not affect the return of the machine.

Online Slots with the Highest Return to Player

Slots are by far the most popular casino game on the internet and in land-based casinos. So it's definitely worth looking at which slots bring the lowest profits to casinos.

Top five online slot machines with the highest return to player:

• Ugga Bugga (Playtech) - 99.07%
• Blood Suckers (NetEnt) - 98%
• Rock On (Rival) - 98%
• Cosmic Quest (Rival) - 98%
• Break Da Bank (Microgaming) - 98%

At this point, it must be said that these are very high numbers. By default, online slots offer a return of between 94% and 96%. Slots in land-based casinos have the house edge even lower. For example, the lowest possible (by law) house edge for slots in Vegas is 70%.

Skill Games with Player's Edge

We are slowly moving from the games of chance to games where knowledge and experience will help you outsmart the casino. Yes, with these games you can, under certain conditions, gain a mathematical advantage over the casino.

You can get a small, but still, an advantage in video poker Deuces Wild. However, you must meet two requirements.

• You need to know the optimal strategy for Deuces Wild
• It must be a type of Deuces Wild game called Full Pay.

If you meet both conditions, the theoretical return will reach the desired 100.76%.

The second game, in which you can gain an advantage over the casino thanks to your skill, has certainly occurred to you. It is Blackjack. Calculating the house edge in blackjack is a rather complicated thing. The number varies depending on the rules and the number of cards played. However, it is generally reported to be somewhere between 0.5% and 1%. Again using the optimal strategy.

However, thanks to card counting techniques and bet changes, it is possible to turn a casino's advantage into a player's advantage. Specifically, it is about how many ten cards are in the deck. This tells us the so-called true count that card counters keep. The higher the number, the more ten cards in the deck and the better the situation for the player.
