Ranking Methodology for the Best New Slots in the UK

RTP Rate:

Reviewing a slot should always include information about its RTP rate. This is one of the most important aspects when playing online slots.

Best slots have RTP rates over 96%, which is the average in the industry. This percentage determines the amount of money returned to the player after a specific number of plays. A higher rate will mean wins are more likely.


A slot can only be considered good when it offers great and versatile playability. Several aspects are taken into account when evaluating this:

A great slot should have top-notch graphics and an immersive soundtrack. It should offer a wide range of bets. Top-rated slots will also have a bigger number of paylines, which can increase winnings. And finally, symbols should be high-paying and have special features. Be assured all of our reviewed slots have a combination of these criteria.

Bonuses & Promos:

A great slot will offer bigger and better wins. The higher the prizes, the bigger the number of players it caters to. We evaluated these slots’ maximum wins and jackpots (if applicable).

We also went ahead and looked at the different bonus games, such as bonus spins. Extra spins are one of the most sought-after bonuses when looking at online slots. This means a great slot will have fair and regular extra spins bonuses.

Our team also focused on the bonuses offered by the best slots sites in the UK for slot games.
