Is it Safe to Play at New Slot Sites?

Absolutely! We understand that this is a question that many people do have. However, we can 100% assure you that it is safe to play at new slot sites. You will need to do a bit of due diligence. In the United Kingdom, for an online casino to offer services to customers within the country, it needs to be a member of the UK Gambling Commission. It is tough, and expensive, to be a member of the UKGC. Once you are in, you have to follow some pretty strict rules too. Therefore, if a site is a member of the UKGC, then you are safe. If they are not, then give them a skip. Not worth it at all.

Why Play at New Slots Sites?

Better Casino Bonuses

This is one of the main reasons why you should absolutely be gambling at new sites. As you may know, the world of online casinos is incredibly competitive. It can be tough for an established site to stand out, let alone some of the newer ones.

Of course, there is one thing that online gamblers love; free cash. In our experience, it is the new slot sites which tend to offer the best casino bonuses. Not just welcome bonuses, but there will often be a lot of loyalty bonuses to sink your teeth into too. If you are mostly looking for online casinos which focus on slot players, then you may find that many of the bonuses are going to be geared towards you. For example; you may find several bonuses such as free spins, or extra bonuses for playing on slot machines.

Better Customer Support

New slot sites tend to offer better customer support for a couple of reasons:

  • They try to ensure that they get good ‘word of mouth’ feedback, which drives more people to their website.
  • They have fewer players, which means that they can spend a lot more time talking to their players to ensure that they are receiving the customer service that they need. We have seen some older, more-established sites which treat their players like cattle. They want you dealt within minutes. It is not fun.
Better Site Functionality

The problem with many of the more established online casinos is that they are stuck in the past. We have no doubt that they would love to move their business forward, but they can’t. They have to deal with their customers, and customers are not the world’s biggest fans of change, after all.

Newer sites do not have those online customers to cater to. This means that they can make their site layout a little bit better. Their sites are easier to use overall, which makes it so much more exciting.  In addition to this, the mobile site on some of the best online new slot sites will be better. This is handy, since the vast majority of people who gamble online tend to do so through their mobile devices nowadays. Even if you are not planning to do it right now, we have no doubt that it is something that you will be doing in the future.

More Games to Play!

Some of the older online casinos tend to be stuck in contracts with certain game companies. This is a bit annoying because you could end up missing out on playing a whole ton of new slots. New slot sites tend not to have these contracts. They have a plethora of different games that you can play from a multitude of different vendors. This means that you only need to register on one side, rather than several different ones. Ideal if you enjoying playing slots!

Unique Casino Product

You'll often find that new UK slot sites are designed in a unique way or offer something innovative that could be a fun rewards system, zany theme, interesting designed mobile site, a standout games catalogue. This is because the UK slot site market is fiercely competitive and new UK slot sites need to stand out from the crowd. If they don't then there's always another new one that'll attract customers. 

New means new, but the operating company might not be

Just because a site is new, doesn't mean that they're totally fresh with anew casino company running things. Most of the time, established casino companies launch new brands and new sites as part of their business plan to keep on attracting new customers. In this day and age, casino customers aren't  "faithful" anymore and are used to jumping ship to a new casino in search for a new experience, better games choice and bigger and more lucrative bonuses. What's a casino to do? Launch a new slot site of course!

We prefer new slot sites that are owned and operated by long-established companies because you can not only trust them with your money but you can always be sure that they know what they're doing to give you a top draw casino experience. This is why there are loads of sister casino sites out there!
