How is the ranking of the casino test winners determined?

The order of the online casinos in our best list is determined by the ratings that the casinos receive in the test. Therefore, the highest welcome bonus does not necessarily mean the first place in the list. Instead, what matters in every online casino test are the licenses, payment methods, game selection, and fair bonus conditions.

That’s why we not only choose an overall winner, but also various category winners. This way, our players can always find the casino that best suits their needs. All the online casinos and arcades featured are safe and reputable.

About us – The editorial team

Every day we test, review, and evaluate new online casinos as a team. We call ourselves specialists because we have more than 60 years of combined casino experience.

We have poker players, blackjack professionals, roulette enthusiasts, and players with years of experience at slots and jackpots working on our online casino reviews. In particular, our editors-in-chief, Carlos and Lucas, have been playing and winning before online casinos became a trend.

We are not only experts, but also passionate players.

Our honest and detailed reviews are the result of hours of playing and testing.

As a team, it is our goal to present you as a player with a comprehensive and objective view of reputable online casinos, along with all their advantages and disadvantages. We provide information on various casinos so that you can find the best one that suits your needs.

In order to achieve this, we strictly adhere to our defined editorial guidelines and do not enter into any advertising contracts. Instead, we only have affiliate contracts with online casino operators. This ensures that our work remains independent and unbiased.

Our test factors for serious casino reviews

Every casino test is conducted by us according to standardized specifications. This allows us to create fair conditions for comparing casinos. Below, we explain the most important points of our online casino tests.

Licenses and Security

Our online casino tests always begin with a review of the casino’s license and security features. If we find any discrepancies in this area, the casino is not further tested.

Some of the safe casino licenses include:

If the casino test shows that the license is valid, we then proceed to check other security features.

Important test points here are:

Designation Function
SSL Encryption Encryption of the website, ensures data security
eCogra Protection against manipulation of payout odds, test lab for casino games
iTechLabs Protection against manipulation of payout odds, test lab for casino games
BeGambleAware Gamblers protection, gambling addiction help for gamblers and relatives
GamblersAnonymous Gamblers protection, gambling addiction help for gamblers and relatives
BZgA Spielerschutz, official authority for gambling addiction support in the USA


All reputable casinos must have SSL encryption. Players can quickly recognize this by the lock icon in the browser and the “S” at the prefix HTTPS in front of the URL.

Online casinos with EU licenses

Countries that issue secure EU licenses for online gambling include Malta, Curacao, Gibraltar, and the Isle of Man. The online casino licenses stand for security and seriousness and have been active for many years. For our US online casino tests, licenses from Malta and Curacao are particularly important – we have already tested more than 400 online casinos that can show these licenses.

Online casinos with US license

Since July 2022, there is a new US license in accordance with the requirements of the State Treaty on Gambling (GlüStV). Online gambling establishments are required to meet strict criteria regarding game selection, limits, stakes, and other aspects. These requirements impose significant limitations on certain players, which is why online casinos with EU licenses continue to remain highly popular. In our casino reviews, US gambling halls are pitted against online casinos with EU licenses.

Secure payment methods in online casinos

When it comes to payment methods, no compromises should be made. Here, only online casinos pass our tests that offer reputable and verified payment methods for casino players.

In the casino tests, providers with the following payment providers perform well:

Casinos with cryptocurrencies

All crypto casinos

  • Casinos with Skrill

  • I need to emphasize Casinos with Paysafecard deposit. The prepaid card is one of the safest payment methods. Your data is not shared and at the same time you always have your budget in view.

    PayPal is only available with a US license, while cryptocurrencies are only available with a license from Curacao.

    Game offer and variety

    When it comes to the game offer, we strive for balance. Slots will always make up the majority, but we also include progressive jackpots, table games, video poker, and a high-quality live casino. However, scratch cards or bingo are not the determining factors in our casino tests.

    Here’s what we pay close attention to when evaluating the range of games:

  • software

    Game developers

  • casinos high rtp

    Payout ratios

  • slots

    Slots & Jackpots

  • poker

    Table and card games

  • casino live

    Live Casino

  • casino games

    New Games

  • Based on the game providers used in the online casino, we can immediately determine which casino games can be offered. Thus, the game selection depends on the game providers. Among the best and most popular software providers in online casinos are the following companies:

  • net entertainment

    Best NetEnt Casino

    NetEnt Casinos

    Best Game


  • microgaming

    Best Microgaming Casino


    Best Game


  • playtech

    Best Playtech Casino

    Bizzo Casino

    Best Game

    Age of the Gods

  • yggdrasil gaming

    Best Yggdrasil Casino


    Best Game

    Big Blox

  • 1x2gaming

    Best 1×2 Casino

    22bet Casino

    Best Game

    Aztec Secrets

  • merkur gaming

    Best Merkur Casino

    Bizzo Casino

    Best Game

    Eye of Horus

  • Best Novomatic Casino


    Best Game

    Book of Ra Deluxe

  • play n go

    Best Play’n Go Casino

    N1 Casino

    Best Game

    Book of Dead

  • We also highly rate casinos that exclusively feature the two major game manufacturers Microgaming and NetEnt, as long as they provide impeccable service, high betting limits, and above-average payout ratios, among other features.

    Payout ratios are especially crucial and should be checked repeatedly. We consider a payout ratio of 94% or higher to be fair for the player.

    The payout ratio (also known as RTP = Return to Player) indicates how frequently a casino game pays out. A 96% payout rate means that, on average, players receive $96 for every $100 bet.

    The random number generators (RNG) are hard-coded and are checked by independent organizations in the casinos tested by us and shown here. This way, cheating on the games can be ruled out.

    Test labs that monitor the random number generators, but also the casino software, are for example iTechLabs and eCogra.

    There are thousands of slot machines on the market, so some casinos offer up to 8000 games. The number of slots alone does not win any prizes with us, but if a casino has many slots to choose from, our online casino experiences show that safe providers are often present.

    Online casinos do well in this category when we see, among others, the following slots in the test:

    When it comes to jackpot slots, we expect a smaller selection in our casino tests. Progressive jackpots are especially popular in our community. Jackpots in the millions can be won here. In addition to progressive jackpots, there are also local jackpot slots. Here, the jackpots rise to several hundred thousand euros and thus also offer a good incentive to play.

    For jackpots, we look out for the following names:

    Every casino player enjoys playing a round of blackjack or roulette. We consider these classic table and card games to be standard for every online casino, and we deduct points if they are not available.

    The US casino license prohibits the inclusion of table and card games in online casinos. In order for us to compare casinos fairly, we have to deduct points from casinos with a US license for this reason.

    Video poker is a pleasant pastime. It is played against the computer and there are various variants available. We find the multi-hand video poker games to be particularly interesting. While it may not provide the same excitement as a real poker game, video poker is still a “nice to have” feature in every online casino and serves as an indicator for our online casino comparison.

    Live casino streams have revolutionized the online casino industry in recent years. In our online casino tests, many providers excel in this area by using the live streams of Evolution Gaming, Pragmatic Play Live, or Ezugi.

    This means that the games are conducted by trained croupiers and dealers, creating an authentic casino experience projected onto the screen.

    The classic games are particularly impressive in this format: Live Dealer Blackjack, Live Roulette, and Live Dealer Baccarat are the most popular games in the live casino. Additionally, there are interactive game shows such as Monopoly, Wheel of Fortune, or Deal or No Deal.

    A strong live casino is highly valued in our casino reviews and is extensively played during every test.

    Casino app and mobile gaming

    We test online casinos on iPhones, iPads, and Android devices to ensure that they can be played anywhere – that’s the real advantage of online casinos.

    Meanwhile, casino operators are already prioritizing mobile use by optimizing the operation and games for mobile devices.

    However, players need to have a constant internet connection and keep their browsers up to date.

    We believe that native casino apps for download are rare and unnecessary. Instead, we focus on the user-friendliness of the mobile web app in our mobile casino tests.

    Attractive bonus offers and promotions

    Many players look at the amount of the welcome bonus and then choose the casino with the highest bonus. This is definitely a valid approach, however, high bonus offers do not always perform well in our opinion.

    Instead, it is about finding a balanced ratio between the bonus amount and the turnover requirements. Additionally, we always welcome various bonus offers for existing customers.

    A welcome bonus is offered by every online casino that we have tested. This bonus offer is exclusively available to newly registered players. Particularly important to note are:

    • Minimum deposit
    • Activation period after registration
    • Validity period from the deposit
    • Valid games for the bonus

    Reload bonus offers are bonuses for regular players. These offers are credited for reloading the player’s account.

    A mix of fixed offers, such as a 50% bonus for repeat deposits, as well as changing bonuses, such as new promotions every month, ensure positive reviews in our casino tests.

    The most sought-after offer in online casinos is the no deposit bonus. Here, you have to register, verify your email address or phone number, and usually receive free spins for a specific slot.

    Bonuses without a deposit are a very good start in an unknown casino. However, the turnover requirements for winnings are often very high, so you have to be careful as a player here.

    Since a no deposit bonus is always very popular, an online casino review here often turns out positive. If the turnover conditions are also fair, this ensures a very positive start to the casino experience.

    Free spins are also very popular. Here, too, we look very closely at how the turnover conditions of winnings from the free spins are. In our casino tests, we sometimes come across many free spins, but winnings then have to be wagered 50 times or more. This is where the fun really stops.

    What are fair bonus conditions?

    A very frequent question from our community is what fair bonus conditions are. Which conditions we consider fair, we show you here:

    Bonus condition fair requirement
    Minimum deposit Standard bonus: $10 – $20, Highroller bonus: $1000
    Turnover welcome bonus 30 to 50 times deposit and bonus
    Turnover bonus without deposit maximum 50 times turnover of winnings
    Deadline to activate bonus at least 7 days from registration
    Time limit to play through bonus at least 14 days from deposit
    Eligible games Slots at 100%, card games at least 10%, roulette at least 5%.

    Safe and reputable customer service

    Customer service is a crucial aspect. We strive to minimize our need for customer service, but when we do require assistance, it is important to have swift and competent support.

    During the casino test, we evaluate the following contact options:

    • Live Chat
    • Contact form / e-mail
    • FAQ section
    • Extra points are awarded for a toll-free hotline

    Casino operator

    Building a successful online casino takes a lot of time, money, and nerves. Therefore, companies often operate multiple online casinos. Our online casino reviews always include information about the operator, so you can get an idea of which names are the major players in the industry.

    Some well-known casino operators and their top-performing casinos are:

    Casino Operator Number of Casinos in 2023 Strongest Casino of the Operator
    Dama n.v. (Established: 2019) 70+ King Billy Casino
    Rabidi n.v. (Established: 2019) 20+ Playzilla Casino
    N1 Interactive Ltd (Established: 2020) 40+ N1 Casino
    TechSolutions Group N.V (Established: 2017) 4 Bizzo Casino

    A well-known operator always demonstrates sufficient financial security. This is crucial for you as a player. You can confidently request withdrawals, as they are also approved without any issues at our reputable casinos operated by well-known operators.

    At the same time, these operators also have a reputation to uphold. They do not want to tarnish their reputation. Therefore, they are often very loyal and friendly to their valued customers.

    Online casino test by Stiftung Warentest

    Stiftung Warentest and other product testers repeatedly issue blanket warnings against online casinos. We understand the criticism, but there is a clear distinction between occasional casino testers and online casino specialists.

    The criticism primarily focuses on EU licenses and the option to recover lost funds from these casinos through legal means. While there have been cases where players have successfully recovered their money, the specific circumstances are often unclear.

    We agree with Stiftung Warentest’s viewpoint that players should exercise caution and only bet money they can afford to lose.

    Moreover, every player must be aware that online casinos, sports betting, and lotto are always forms of gambling. There are probabilities of winning, but no certainties or promises of winning. All this information is publicly available and must be taken into account.

    Our criticism of the online casino tests conducted by Stiftung Warentest and online casinos tested by Chip and Co begins here. Instead of providing well-founded tests of online casinos in the USA, they mention horror examples and dangers.

    New online casino tests

    Every day, we discover new online casinos and operators who approach us for a casino test. As a result, our days are filled with searching for the most reliable casinos. We publish new online casino tests after conducting a thorough examination that lasts at least 4 weeks. Additionally, we frequently revisit these casinos to ensure that our test reports are always up-to-date.

    Crypto Casino Tests

    Online casinos with a license from Curacao are permitted to accept cryptocurrencies as a form of payment. These types of casino tests are particularly exciting for us, as cryptocurrencies often generate controversy. In the world of online casinos, you can easily use Bitcoin, Litecoin, Ethereum, Ripple, and other cryptocurrencies without any issues. That is why we are big supporters of crypto casinos.

    Cryptocurrencies do not alter our methods for casino tests. Crypto casinos must also prioritize security and player protection.

    Casino tips for new players

    The most important tip for new players is always to enjoy everything in moderation. This starts with the Depositing and withdrawing real money and goes all the way to the playing hours. Whether you’re a beginner or a pro, we always recommend starting with small amounts at new casinos and not going all out right away.

    At the same time, however, you can rely on the casino tests. The casinos presented on our site are safe, reputable, and licensed – some of them also rank internationally among the best online casinos.

    I asked every writer on our editorial team and summarized the best casino tips here in a list:

  • 💰

    Pay attention to bonus conditions and T&Cs: Unfortunately, there is no way around the fine print when playing online casinos. In our casino reviews, we summarize all bonus conditions in bullet points. This will save you time and headaches.

  • casinos-new-icon

    Read casino reviews: It’s not meant to be self-promotion, but we test casinos so you don’t fall for any scams. All casino tests published by us are real testimonials from reputable online casinos.

  • 📜

    Security is above risk: Never take too high a risk. Every casino you play at must have security features such as a valid license and secure payment methods.

  • casinos-real-money-icon

    Stick to a strict budget: Never exceed the budget you have set. When playing at an online casino, it is essential to always abide by the terms you have established. Experienced players know when to stop, ensuring that it remains enjoyable and does not become addictive.

  • 💳

    Start with small stakes: Always begin a game with small amounts, both when depositing and when placing bets. It is advisable to make multiple deposits if your budget allows.

  • Limit your playing time: In addition to having a monetary budget, it is also important to set a time limit. It is crucial to avoid getting too engrossed and to simply leave the casino when your allotted time is up.

  • Always play responsibly

    Online casinos are there to provide entertainment. While winning big may be a dream, it should never be the sole focus. We are aware of many videos showing players winning large sums of money and making it seem like luck, but we have reservations about the authenticity of some of these “random” videos and streams.

    Therefore, the following principle always applies: play responsibly!

    Do not let yourself get carried away with excessive gambling. Instead of relying on intuition, always set limits in advance and stick to them.

    You can seek assistance with responsible gambling from independent organizations. These services are available to everyone, even if you do not have a gambling addiction but simply wish to discuss your gambling behavior.

    Coming directly from the online casino sector, there is the international organization GamblingTherapy. However, ultimately, you can turn to any organization you can find.
