The odds of placing a bet at an online casino vary depending on the particular games you choose to play, their regulations, and the bets you make. The “house edge” or “casino return percentage” refers to the inherent advantage the casino has over players. This shows that over a long period of time, the casino routinely hoards more cash than it pays out to players.

Probability of Winning in Various Casino Games

We’ve developed a list of well-liked casino games and calculated your chances of winning at each one.

Online Blackjack

Your online blackjack chances are influenced by several factors. It’s crucial to understand the rules of a specific game and the strategy you adopt. Generally speaking, a well-thought-out approach can reduce the house edge to 1–2%.

In the game of blackjack, your goal is to get as close to 21 points as you can. Keep in mind that in order to win, you must always have more points than the dealer.

Card counting is a tactic that can increase your chances of winning. With the use of this technique, you may predict the cards the dealer might hold with a high degree of likelihood, allowing you to make a successful wager.

Remember, chance is always a factor. Even with the most calculated strategies, the possibility of losing your bet remains. Before embarking on a game of blackjack, it’s essential to thoroughly understand its rules.

Understanding the value of each card in a deck is also crucial in gambling games. This knowledge allows you to gauge whether drawing another card could result in a bust.


Winning odds in slots are determined by the Return To Player (RTP) percentage. Generally, the higher the RTP, the more money you’ll potentially recover over time. The RTP usually ranges between 85% and 98%.

Some slots advertise a potential return of 99% of your bet. Simply put, if you bet $100, you could potentially recover $99, with the remaining $1 being the casino’s profit.

Before playing slots, it’s advisable to familiarize yourself with responsible gambling rules and read reviews about the game. This helps you understand the game’s volatility, the frequency of winning combinations, and more.


Roulette comes in several variants, each offering different winning odds. For instance, European roulette has a house edge of around 2.7%. In contrast, American roulette increases the house edge to 5.26% due to the inclusion of an extra double-zero slot.

To increase your odds of winning at roulette, it’s advisable to opt for the European version. It’s also crucial to understand the probability associated with each specific bet. For instance, if you place a bet on even or odd numbers, you have a 50% chance of winning. The same probability applies to betting on red or black; you either win or lose.


Poker’s distinctive attribute is that you’re playing against other participants, not the house. However, the casino does charge a commission (known as rake) for your participation in the game. Unlike other games of chance, your poker-winning probabilities largely hinge on your chosen strategy, your opponents’ skill level, and your proficiency at the game.

While learning the rules of poker can be achieved in a few hours, mastering the game can take years. Even seasoned players occasionally falter in choosing the correct strategy, resulting in a lost round and depletion of their bankroll.

Video Poker

Video poker is a hybrid of traditional poker and slot machines. Your chances of winning depend on the specific game you select, and your strategy plays a significant role.

In certain versions of video poker, implementing the correct strategy can potentially boost your odds of winning up to 100%. An appealing feature of video poker is the ability to practice in demo mode, enabling you to test diverse strategies and tactics without risking any real money.


It’s vital to remember that the outcome of any single gaming round in a casino is largely influenced by random factors, primarily because gambling operates on the principle of a random number generator. Over time, your chances of winning can increase.However, there are virtually no guarantees of striking it lucky, or preventing the next player from hitting the jackpot right after you. It’s crucial to keep in mind that casino games are primarily a source of entertainment, and you should be ready for the potential loss of your money. If you opt to play at an online casino, setting your own limits and adopting a responsible attitude towards gambling is highly recommended.
