New Slots Site with Best Sign-Up Offer: bCasino

A great welcome bonus can take one of the new best slots sites to the next level. While a new site tries to establish a reputation as a trustworthy brand, their ability to deliver a large amount of bonus funds to players can push them into the mainstream in a hurry. In the case of bCasino, that is exactly what has happened. bCasino has one of the best welcome bonuses in the industry. It isn’t just an elite welcome bonus among new slots sites, but among all slots sites.

Currently bCasino offers 100 free spins and up to £1,200 bonus, which is why bCasino deserves rank number one in the sign up offer ranking. As far as new UK slots sites are concerned, you could definitely do worse than their bonus. The wagering requirements are relatively reasonable (30x), and the minimum deposit amount for this type of bonus usually stands at £20. And besides the generous welcome package, bCasino also has some great recurrent promotions for existing players.

New Slot Site with Best Variety Of Games: Rainbow Riches 

When it comes to games variety, most slots sites have a large variety of games to choose from. In terms of games variety, it is a case of the haves versus the have-nots. Either you have hundreds of games to choose from, or you don’t. In the case of these new slots sites, having a large games variety is essential to break into the upper echelon in the industry.

We have to recommend Rainbow Riches for featuring a fantastic selection of casino games. Whether you are looking for Rainbow Riches slots or other casino games, you’ll most likely find them with this brand. This new slots site offers the bulk of those games being in the slots category.You can also find lots of Rainbow Riches games to be free play which are worth giving a go. Among those games are popular games like Jurassic World to complement the classics. That kind of depth in a games library does a lot to keep the games you want to play fresh.

New Slot Site with Best Mobile App: Rizk

Having a mobile app is not a requirement for slots sites. This is especially true for new slots sites, most of which do not have dedicated apps. Instead, these sites are more frequently being designed to be on both desktop and mobile devices. That responsive design has rendered slots apps less popular. However, some sites do have apps, and those that do can set themselves apart by giving players a dedicated place to wager. That approach can beat sharing a mobile browser with every other website at times.

Rizk Casino offer a very user-friendly app. Their app for mobile devices is available both for Android and iOS platforms. When testing the app we found that there were no issues or any lagging on either of these platforms. Additionally, the website itself is fully optimised for mobile devices and provides players with an excellent user experience.

Of course, there is no shame in being a slots site that relies on a mobile site. In the case of bCasino, their mobile site is done well. It is very clean and the red and white colour scheme translate very well on both desktop and mobile. While the design of a site is a matter of personal preference, a site being easy to use is a necessity.

New Slot Site with Best Customer Service: Party Casino

Customer service is so important in that players having a positive experience with a site is mandatory to them sticking around. That is why it is surprising that some of these new slots sites are lacking in customer service options. Having phone, email, and live chat support is important to accommodate the preferences of every kind of player. Party Casino offers the most modern approach to customer service, namely via live chat or old school, by sending an e-mail. 

The customer service employees are very are professional and helpful and at the same time friendly and polite, they. The customer support service is available 24/7, so your problem will be resolved quickly and efficiently. The website also features a special FAQ section where you can get informed or try to find an answer on your own, before contacting the customer support team.

As you can see, the best slots sites all have their positives. Which one is the best for you can vary based on what you prioritize. Just know that all of them will provide the fun slots games you crave.
