Generally, anything with an RTP of 97% or higher is considered a “high RTP slot”. Here is a quick breakdown of the terms you will encounter at the UK’s best slot sites. We prioritise slot sites that offer fair, high-average return percentages rather than those that consistently choose the lowest RTP settings from developers. Return to Player (RTP) percentages dictate how much a slot pays back over time. If a site drains battery quickly or crashes during a bonus round, it loses points in our ratings. We actively search for a diverse mix of Megaways, progressive jackpots (such as Mega Moolah) and exclusive titles, so you have the best variety at your fingertips.
