The process of a comprehensive assessment of  bookmakers by  Non Gamstop consists of three main stages:

  • Data collection
  • Website testing
  • Expert analytics

Our experts

If you think our reviews are written by some academics, you’re wrong. They are written by players just like you. These 10 guys play casino games, bet, deposit and withdraw,  win and lose, and seek assistance at customer support. Do you recognize yourself in this description? The only thing that distinguishes our experts from you is decades of experience. They know how the gambling industry works inside and out and can quickly separate the wheat from the chaff.

Every day they collect information from more than 100 sites, read player reviews, and test the sites themselves. As a result, they prepare fresh reviews to achieve maximum accuracy for the Non Gamstop Bookies review section.

Hi I’m Charles Greene your humble author of I’m an avid sports and money fan, and my main goal from a young age was to combine the two (sorry I never realized it as a footballer). At the age of 20 I found a great opportunity to make money from my passion for sports, it was betting.

After working in TV, Matt turned his focus towards numbers, specifically odds. He has been with us since 2016 and serves as SBD’s Editor-in-Chief, credited with creating our futures trackers, SBD’s score predictor, SBD Sharp, and his own model for calculating NFL SOS, among other products.

Now let us look more closely at factors that our experts take into account when they rank betting sites.

​Key factors in the assessment of Betting Site

Now you will learn about the most important factors that our experts take into account when making an opinion about any betting site. If you are going to read this text to the end, then be patient. Because there are many such factors. We truly evaluate sites from many angles so that our readers can get the most accurate and complete picture of each bookmaker and make the right choice.

License and security

First, we want to know how safe and secure the betting site is. We check if the bookmaker has a license from respectful authorities like the United Kingdom Gambling Commission (UKGC), Malta Gaming Authority (MGA), Curacao eGaming and others.

Secondly, we investigate the overall security of the site. This includes checking if the website has encryption to protect the data, SSL certificates, firewalls, and two-factor authentication.

Thirdly, we are looking for other evidence of the trustworthiness of the online bookmaker. These could be certificates from independent agencies, such as eCOGRA, IBAS, Independent Auditors and others.

Fourthly, we carefully study the Terms and Conditions and identify pitfalls that can negatively affect players

Finally, we pay attention to game providers for online casinos. We want to be sure that the game outcome is not rigged in favour of the bookmaker.

Reputation of the betting site according to players

The opinion of players is of great importance in evaluating a bookmaker. Our experts read player reviews left on various sites. Often players highlight the most negative sides of the bookmaker or talk about scams. However, we also take into account positive feedback.

Both positive and negative feedback from players is important to us when ranking online betting sites.

Deposits & Withdrawals

Great betting sites tend to offer a wide range of legal payment methods. Among them are   Visa and Mastercard, PayPal, Neteller, Skrill, and Bank transfer. In the modern world, cryptocurrencies are becoming increasingly popular payment methods among players. We consider this an additional advantage for the casino if it still has a license and operates within the legal framework. The more payment methods online casino offers the more choices are there for players. 

Another factor is how long it takes to pay out the winnings. The faster this process, the more valuable this bookmaker is to us. However, it must be said that here a lot depends on players and what form of deposit and withdrawal they choose.

Other important things are the minimum deposit, cash-out limits, and withdrawal fees. The best betting sites tend to charge no fees on deposits and withdrawals or they are tiny. Again, any applicable commissions should be clearly stated on the bookmaker’s website.

Sportsbook and Markets

A sportsbook is an essential component of an online casino for those interested in sports betting.  It should include a variety of international and local sports events, virtual sports, and esports. The wider the range of markets, the better. Bookmakers that offer players multiple betting options are usually the best places to bet, and they receive higher ratings from our experts.

In-play betting & Live Streaming

Bookmakers with high ratings usually offer streaming services and a great selection of live betting. That is because more and more people today like to place bets on sports events while they are in progress. Demand for n-play betting and live-streaming is growing, and we expect such tools to become even more popular in the future.

Bonuses and Promotions

Who among the newcomers wouldn’t like to get a generous welcome bonus? In addition to the welcome bonus, our experts also pay attention to promotions for existing customers like enhanced odds, risk-free bets, cashback, acca insurance, as well as many other offers focused on specific sports. We take into account the number of bonuses and promotions offered by bookies and their total amount.

Betting odds

Betting odds for the same event may vary from bookmaker to bookmaker. They assess the risk associated with each event differently. Experienced bettors will often compare odds from multiple bookmakers to find the best option for their bets. The best odds can make a significant difference to potential profits.

All the bookies rated highly by Non-Gamstop Bookies offer more favourable odds for their customers. 

User-friendly design

In the long run, players stay with those bookmakers who take care of gamblers and make their stay on the casino website as comfortable and enjoyable as possible. That is why the design of a betting site matters to us. Our experts browse each casino website to understand its user-friendliness. They give high scores to those sites that have intuitive navigation and run smoothly. 

Mobile Betting

Nowadays many gamblers use their phones to access online casinos. So it is important that betting sites are also mobile-friendly. We believe that an excellent betting website should have a fully optimised version for mobile betting which differs nothing from the desktop version or it should have an app that works both on Android and iOS.

Our review experts meticulously study how each site element works on a mobile device. If they notice any inconsistencies, they point it out in their reviews.

Customer Service

If problems arise, players contact customer support. An excellent bookmaker website has a live chat available throughout the day. In addition, the website should offer other ways to contact brand representatives: email addresses, and phone numbers. Some even offer social media channels for communication.

But it is not enough just to have a support service, it must also be fast and efficient. Therefore, our experts check the speed at which the client receives a response. In addition, our experts evaluate pre-registration support options and separate assistance for VIP clients.

They also read the FAQ page, which often contains answers to the most common questions a punter may have.

Why don’t I find some reputable bookmakers in your top-notch list?

If you like a particular online bookmaker, it won’t necessarily be on our list of the best sites. The fact is that new, better bookmakers are constantly appearing and gaining leading positions. Competition in the gambling industry is very high. Therefore, we advise players to read bookmaker reviews from time to time.
