The best paying casino games

The solvency of casino games depends on several key factors. The most important of them is the return to player factor, abbreviated as RTP (Return to Player). The higher this indicator is in a given casino game, the greater your chances of winning are statistically speaking.

In addition to the RTP, the game's variance (volatility) also affects the profit potential of the game. High variance means rarer but potentially larger wins. In turn, low variance means more frequent but smaller rewards.

Below we present the best paying casino games in popular categories.

RTP of casino games

RTP (Return to Player) is a percentage that determines what percentage of the funds deposited by players will be returned in the form of winnings. In other words, it tells us what our chances are of getting back some of the money invested.

The RTP in casino games of chance is usually in the range of 92%-99%. The higher the game's RTP, the more statistically speaking you have a chance of winning. Below are examples of games with high RTP:

Regulations of Online Casinos in Poland

The online casino market in Poland has been regulated relatively recently. Although the so-called Gambling Act was passed in 2009, initially the regulations did not apply to playing on the Internet. This legal act initially defined the rules for establishing and operating land-based casinos, as well as bookmaker establishments.

Only subsequent amendments, including the latest one from 2021, introduced regulations that are still in force today. It has been established that online casinos must operate on the basis of a state license, but it is not issued to private entities from Poland and abroad. The only casino with a state license is Total Casino. It is run by the state-owned company Totalizator Sportowy, which is better known as the organizer of the Lotto lottery that has been operating for several decades.

Players from Poland are therefore more likely to choose casinos with international licenses located in foreign jurisdictions. Registration and play in these casinos is possible thanks to the interpretation of the Common Market principle in force in the European Union. Access to foreign entities cannot be restricted, as it is inconsistent with the provisions of the Economic Communities.

Unlicensed Online Casinos

Regardless of which casino you choose, your priority should be to avoid one red flag. These are online casinos that do not have a license to conduct online gambling, or those whose license has expired and has not been renewed.

By playing in such casinos, you not only expose yourself to unfair play and loss of money. They remain beyond the control of supervisory authorities, so in these casinos no one controls the course of the game, declared return rates or customer service. Withdrawing money may also be a problem because such casinos may not even be registered as companies. In addition, unlicensed casinos may sell your personal data, as well as the documents you submit for verification purposes.

Criteria for choosing a solvent casino

When choosing a solvent and safe online casino, it is worth paying attention to several key criteria:

  1. 🔒 License and certificates – make sure the casino has a valid license issued by a reputable supervisory authority, e.g. Malta Gaming Authority, UK Gambling Commission or Curacao. Additional security certifications (e.g. eCOGRA) are also a good sign.
  2. 🎰 RTP Ratio – Check the average return to player (RTP) offered by the casino. It's good when the RTP exceeds 96%, which gives you higher chances of potential winnings.
  3. 💲 Payment methods – make sure that the casino cooperates with reputable payment operators, accepts your preferred deposit/withdrawal method and does not impose additional fees in this regard.
  4. 👍 Player Reviews – Read reviews about payouts, customer service and overall experience. They can be a valuable tip when choosing a casino.

How to assess whether a casino is solvent?

Here are some tips on how to assess the solvency of a given casino:

  1. 🔎 Check the license and regulations - make sure the casino has a current license and operates legally. This is the basis.
  2. 📊 Analyze the RTP and variance of games - the higher the return to player (RTP) and variance, the better. This means statistically higher winning potential.
  3. 🕵️ Check the reports of independent auditing companies - the casino operator's practices can be checked, for example, by eCOGRA. Audit reports ensure the reliability of operations.
  4. 💳 Pay attention to the speed and fees when withdrawing money - the more convenient and faster you can withdraw funds from your player's account, the better.
  5. 📢 Read the opinions of other players - players willingly share their experiences regarding withdrawals of winnings from a given casino.

Customer service in a solvent casino

The key element influencing the comfort of playing in an online casino is the quality of customer service. The best online casinos provide quick contact with helpful and competent support in key issues for the player:

  1. 📞 Call Center – ability to talk to a consultant by phone.
  2. 💻 Live Chat – live chat allowing instant contact with customer service.
  3. ✉ E-mail – possibility of explaining the problem in detail or asking a question via e-mail.
  4. 👪 Social media – additional contact channel via FB, TT, IG, etc.
  5. 🇵🇱 Polish language - the ability to communicate in their native language is crucial for Polish players.

As part of customer service, solvent casinos should also provide detailed FAQs in which players will find answers to the most common questions.

What is the highest return to player rate

The highest theoretically possible RTP (return to player) in online casino games is 100%.

This would mean that the player receives back exactly 100% of the amount he deposited. In practice, however, no casino offers such an RTP, because it would mean no profit for the operator.

Realistically speaking, you won't find an RTP higher than 99% on the Internet. This is the 99% return for the player guaranteed by the game manufacturer NetEnt in the legendary Mega Joker slot. No other slot has broken this record so far.

What is the lowest return to player rate

According to the guidelines of most online casino licensing authorities (e.g. Malta Gaming Authority, UKGC), the lowest allowed RTP for gambling is 80%.

This means that with such a low return rate, the player only receives 80% of the deposited funds in the long run. The remaining 20% goes into the casino's pocket.

In practice, however, it is difficult to find a legally operating casino that would offer games with an RTP below 90%. As a rule, the return remains at the level of 92-99%, and the higher the better for the player. It is good practice to choose games with an RTP above 96%.
