🛡️Why Trust JohnSlots?

At JohnSlots, we prioritise our readers’ experience above all else. We care about more than just providing you with reviews of online casinos and slots—we ensure each piece of information presented on our website holds meaning and is accurate, timely, unbiased, and transparent. That’s because we want you to see that you can trust our review team, and you can do that because we offer:

  1. Industry Experience: Our 12 experts bring a combined 50 years of experience in reviewing online casinos and slot games.
  2. Monthly Reviews: We review between 5 to 15 casinos and 10 to 20 slots each month, ensuring constant, up-to-date coverage of all the new brands and releases.
  3. Transparent Review Criteria: Each casino review takes approximately 60 hours of combined work, including research, data collection, testing, and fact-checking.
  4. Data-driven Analysis: We allocate £120 for deposits and playtesting for every casino review.
  5. Player-centric Approach: “Data Collection and Verification” is the most time-consuming part of our process, taking up to 16 hours per casino.
  6. Regulations Check: Our team dedicates 8 hours to researching every casino or game before beginning a review.
  7. Continuous Updates: In the past year, over 150 casinos have applied to be featured on our website, but only a select few were approved due to our high standards.

✅ Industry Experience

Our review team consists of 12 experts who have over 50 years of combined experience reviewing online casinos and slot games. They know which features are essential in an online casino or slot. They review up to 15 casinos and 20 slots each month, so they know all the traits of good platforms and games as opposed to mediocre ones. Their expertise allows us to publish reviews and guides with unparalleled insight based only on our research, never on other guides or unchecked sources.

✅ Detailed Monthly Reviews

We review new casinos and slot machines each month. When we decide to review one, we ensure that we leave no stone unturned in our testing and review process. That’s why our reviews are always detailed and full of essential information that can make a user’s experience more pleasant. We review the game lobbies, promotions, available payment methods, transaction limitations, fees, terms and conditions, and everything else that shapes a user’s gaming journey. We also pay extra attention to security features and licences, ensuring that all casinos and slots we recommend are safe for users.

✅ Transparent Review Criteria

Are you wondering how we form our opinions of the casinos and games we review? It’s easy—thanks to our expert reviewers, we have a foolproof way of collecting data from each platform or game we test. Our review criteria include essential factors like the availability of top-notch security features, a valid gambling licence from a trusted regulatory body, a game lobby powered by the leading software providers, games with high RTPs and fair terms, bonuses with transparent details and hefty prizes, and so much more. Our experts spend up to 16 hours collecting and verifying data to ensure every review is accurate and trustworthy.

✅ Data-driven Analysis

Each review we prepare for you undergoes hours of preparation and testing. This allows us to provide accurate and detailed information about each part of the casino or game. For example, we’ve calculated that around 16 hours of data collection and verification go into a single review. Our team also dedicates 8 hours to researching the casino or game before we even start the review. Moreover, we invest up to £120 to deposit in an online casino or to test a specific game.

Some reviews take up to 60 hours to prepare, depending on the complexity of the platform we review. But this isn’t a problem – we can test and review for as long as is necessary to provide our readers with the information they need.

✅ Player-centric Approach

Our primary goal is to provide readers with information to help them determine whether a specific casino platform or game meets their standards and preferences. So, we always put ourselves in your shoes and talk about casinos in a way that helps you see the shortcomings and advantages of a specific platform. If the casino has a good UI and easy navigation, we’ll tell you all about it. And we’ll mention if the loading speeds are not up to par. We are here to discuss everything that shapes your experience as a player.

✅ Regulations Check

We will never recommend a casino without checking its licensing status. Regulations are important to us, as nothing short of a valid licence ensures that our readers are safe and secure when playing on a platform we’ve recommended. Thus, one of the first things we review is the licensing status – whether the casino has a licence from a trusted regulatory body.

✅ Continuous Updates

Some promotions expire, some games get redesigned, and some casinos undergo a complete identity change to stay relevant in the ever-changing iGaming market. If an online casino or casino game undergoes a significant change, we are here to tell you about it. We constantly update our reviews to ensure they stay relevant, so don’t hesitate to consult them to see what’s happening with a specific casino platform or game. Our team reverts back every 3 months to verify if all the recommended operators have the same offers, standing, licence, and features.
