The payout percentage, also known as payout ratio or Return to Player (RTP), is an important indicator of the chances of winning at an online casino. It shows what percentage of the game's stakes is returned to casino players on average. However, you should note that the ratios are usually tested over several thousand spins and can't be directly transferred to games with fewer spins. For more information on this topic, we recommend our detailed guide on the casino game payout percentage (RTP).
Variance and Volatility – Differentiation From Return To Player
Before we tell you more about the terms variance and volatility, it's important to understand that they are directly related to payout ratio despite describing different aspects of gambling.
Variance
The game's variance describes the results' range of variation. It represents the frequency and amount of payouts. A high-variance game pays out winnings less often. However, when you win, you win big. In low-variance games, you win more often, but the rewards are smaller.
Volatility
Volatility refers to the degree of risk associated with a particular game. A game with high volatility can lead to big winnings but also to quick and high losses. Low-volatility games, on the other hand, offer more stable but often smaller rewards.
When choosing a game, it's important to consider both variance and volatility, as they are key factors in determining the game's risk and winning potential. They complement the payout ratio, which only gives an average value and doesn't provide any information about the fluctuations of the game.
Here's What You Should Look Out for To Increase Your Chances of Winning
Understanding the game's payout percentage, variance, and volatility is crucial for maximizing your chances of winning. The payout percentage, also known as Return to Player (RTP), indicates what percentage of players' stakes will theoretically be returned to them. A game that has a high payout ratio increases the odds of winning.

House Edge: What Does It Mean?
House advantage is a term used in the gambling industry to describe the statistical advantage that a casino has over players. It's a percentage that indicates how much of the player's total bet the casino keeps on average.
In land-based gambling establishments, the house edge is usually higher than in online casinos. This is due to higher operating costs, which are offset by a higher house edge. The average house edge in land-based casinos can range from 20% to 30%, while online casinos often have a house edge between 2% and 15%.
There are several factors that contribute to the lower house edge in online casinos. These include lower operating costs, a larger player base and intense competition between casinos.
How To Reduce the House Edge?
There are several strategies to reduce the house advantage and increase your chances of winning. Here are some examples:
1. Blackjack: In blackjack, the house advantage can be significantly reduced by learning and applying the most effective blackjack strategy. This strategy provides the optimal action for every possible hand and dealer's card.
2. Roulette: You can't directly influence the house advantage in roulette, but you can place smart bets. For example, bets on red/black, even/odd or high/low have the highest probability of winning even though they offer the lowest payouts.
3. Video poker: In video poker, the house advantage can be minimized by learning and applying the optimal video poker strategy. This strategy varies depending on the specific variant of a game you are playing. It provides you with the optimal action for every hand you might receive.
4. Slots: With slots, you can't directly influence the house edge, but you can choose games with higher payout ratios (RTP). The higher the RTP, the lower the house edge.
5. Baccarat: You should always wager on the banker in baccarat, as this is the bet with the lowest house edge.
Criteria for Choosing the Best Paying Online Casino
When choosing an online casino with high payouts, there are several criteria to consider:
Fair Bonus Conditions
A good online casino should offer fair bonus terms. This means that the wagering requirements should be realistic and reasonable.
Trustworthiness
The trustworthiness of an online casino is another important factor. A reputable casino should be licensed and regulated by a recognized gambling authority.
Licensed Games From Well-Known Providers
It is a good sign if a casino offers licensed games from well-known providers. These games are usually fair and have a high payout percentage.
Game Offer
A wide range of games is also important. A good casino should offer a variety of games, including slots, table games, and live casino games.
Payment Methods
A good[ online casino should offer various secure and convenient payment methods.
Customer Service
Providing good customer service is also crucial. A good casino should have round-the-clock customer support that responds promptly and efficiently to inquiries.

The selection of slots at online casinos is huge, and finding the games with the best odds can be challenging. The payout percentage (Return to Player, RTP) determines the chance of winning a slot. The higher the payout percentage, the greater the likelihood that a slot will return a large portion of stakes to players in the long run. Here are some slots with the highest payout ratios:
