How We Picked the Best Online Sports Betting and Casino Sites

After you have seen our list of the best online casino sports betting sites, you might be wondering how we came up with the ranking. While we were doing the research, we used a short list of the main criteria, which make an operator great.

Of course, first we need to make sure that the online casino sports betting sites are licensed and certified by multiple entities and independent organisations. After that, we move on to the most important features that we deem make a quality all-in-one platform. You can see the list of our criteria below:

  1. Casino Games – Variety, quality and quantity.
  2. Bonuses – Various types of offers, wagering requirements and payment methods.
  3. Available Sports – Available bets, odds and markets.

When picking the top online sports betting and casino sites, one of the first features we take a look at is the game selection. It is crucial for any reputable operator to feature a wide variety of casino titles, such as slots, live dealer and table games. If the operator can offer titles from top-tier software developers, then that is a great win for both them and their players.

The second most important factor we look at is the promotions that are offered. An alluring welcome bonus is a must here in order to attract new players to the platform. Having regular offers on top of that is always welcome, but not if the wagering requirements are impossible to meet. Hence, all of the operators featured in this article have achievable wagering terms for their bonuses. On that note, it is vital to recommend you casinos with safe cashiers like those of the best online gambling Pay by Phone bill operators.

Finally, we look at the sports betting section of the site. We look at the odds, the types of bets you can place and what markets are featured. It is also a great addition if the platform has in-play betting and live streaming of games. If you would like to see more such operators, then check out our best real money sites in the UK list.

Game Availability

A Showcase of Available Casino Games

In order to get deeper in the topic, we would like to talk about the casino game availability. For an online casino and sports betting site to be considered great, it will need to have a varied game library. Innovation is a major selling point here. This is why eSports bookmakers online are so sought-after. The most popular online casino games are slots, followed by table games and live tables.

Having a great variety of slot games is essential for any reputable operator. We are happy to inform you that all of our best online casino sports betting sites feature hundreds of slot titles.

They are provided by some of the best game developers on the market, such as NetEnt, Microgaming and IGT. For more operators that fit this category, refer to our best UK slots sites list.

As far as other games go, we will need to touch upon the two most popular types of table games in the UK. The first one is roulette and you can be sure that you will find dozens of different variations on each of our top sites. Many punters actually search for operators that are focused on it. That’s why, if you are one of them, you will surely be interested in our best roulette sites ranking.

The second most popular table game in the UK is blackjack. This versatile card game can fit both players looking for low stakes casino sites and high rollers. In this case, you can also find a wide variety of blackjack games that have different betting limits, additional side bets and more. In case that you are a player that is looking specifically for that, we have a list of the best blackjack sites in the UK just for that.

Top Online Casino and Sports Betting Bonus Offers

The second most important criteria that we took under consideration when we made our list of the best online casino sports betting sites is the bonus offers. Usually, operators will have different promotions for each of their platforms. As an example, you can see available bonuses that differ when choosing the online casino, live casino, mobile version or the sportsbook.

This is true for our top operators as well. Most of them have bonuses specifically tailored towards sports betting fans that usually don’t want free spins or extra cash for casino games. That’s why we have made the table below with the available sports betting offers from each of the entries in our list. Make sure to go through them all and pick your favourite.

As you can see, while the sports betting offers do not seem as generous as their casino counterparts, they are specifically tailored towards sports enthusiasts. Of course, there are many operators that offer a combination of both as their welcome promotion, which are present in our best casino bonuses in the UK article.

One thing you should pay attention to is the wagering requirements. Every promotional offer at a gambling site comes with strings attached. While the standard casino wagering terms are not present with sports betting, some offers may have such applied. You may need to bet your bonus multiple times in order to unlock it for withdrawal for both casino and sports offers. For example, some of the best NetBet promo code offers might seem very appealing on the surface, but their T&C should always be looked at beforehand.
