How We Test and Compare Non GamStop Casinos

If you are looking for new slots with a classy touch, Indigo Magic games are a solid option. Having a big publisher is the key for new game suppliers to get their games to a wider audience. New casinos are also benefiting from this, as they only have to sign up with one publisher to get games from a dozen developers. Released in March 2025, Book of Monsters offers a modern twist to the classy book slot category. The new slot is available with an RTP of96.05% and 5,000x win potential. Every review page has a big green ‘PLAY HERE’ button that takes you straight to the casino.

For fast action, Sit & Go tournaments are ideal, and for larger prize pools, multi-table tournaments make more sense. The more flexible betting limits of non GamStop gambling sites give you more control over your budget. Mobile gambling is getting more and more popular, and that’s definitely something newer brands recognise. The best new UK casinos allow you to do everything from signing up, to claiming promos, and making deposits and withdrawals from the mobile site.

Some of the operators that catch bettors’ attention offer appetising reload bonuses on a regular basis. They also run highly competitive loyalty programmes and surprise customers with various weekly or monthly bonuses. The top-rated casinos on this page offer generous sign-up bonuses in combination with a range of appealing ongoing promotions, so be sure to check them out.

Unlike most veteran operators, newer online casinos tend to use software from multiple suppliers. Some even go as far as teaming up with twenty or more developers. This is a big plus, as it ensures customers enjoy an enormous variety of designs, themes and settings that would be impossible if the casino worked with a single provider.

Remember how the UK casino market is very busy, with lots of companies all fighting over a finite number of customers? The situation can be used to your advantage by spreading your game time across several different new casino operators. By having two or more online casino accounts you can take advantage of more promotional offers and have a wider choice of games to play.
