We chose this site because it fulfils our criteria most completely as of this very moment. It has excellent slots from the best providers, a sturdy software platform in Playbook, appealing perks and crucially, it is new and fresh. What’s more, BresBet has received its own unique licence from the Gambling Commission, which is why our players are flocking there! Our first two criteria are based around the quality and quantity of slot games. These days, having only a few slots available from just one or two games developers is not going to cut it.

In this day and age, the player expects to have a few hundred slots to choose from. Some sites have extraordinary libraries of gaming content like Videoslots, which claims to have over 8,600 games as of 2026! That is a staggering number which pretty much includes all the most important software developers so you’re unlikely to miss out on anything if you sign up there. However, in contrast, a site like MONOPOLY Casino has only a couple of hundred slots in its arsenal but we rate the latter much higher than the former for all sorts of reasons. The quality of slots is still incredible, the platform (more on those later) is more reliable and crucially, the promotions are much better. This is an important criteria in our rankings because the industry needs new brands to keep pushing and innovating.
