Whether you’re looking for the best online casino to test out the latest slot games or the best live dealer experience, it can be overwhelming when trying to choose the right operator.That’s why we’ve gone to the trouble of testing 117 regulated UK casino sites in order to narrow down our recommendations for online slots players, live casino enthusiasts and those interested in no wagering bonuses.We don’t use the word ‘regulated’ lightly either. Every one of the 117 online casinos we’ve tested holds a valid UK Gambling Commission (UKGC) license and we can’t stress the importance of that enough. According to the UKGC executive director for operations Sue Young, the gambling regulator referred 1068 websites to search engines for delisting in the last financial year due to them facilitating illegal gambling in Great Britain. That saw 266,667 URLs removed, but the fight against unregulated gambling online continues with the UK government pledging £26 million over three years to help tackle the problem, while Ms Young has vowed to continue “pulling bad actors out at the root”.So it’s fair to say you need to have your wits about you when searching for new online casinos, but we’ve been busy testing and vetting the growing number of legal operators out there, so you can trust any of casino sites we’ve recommended here.To that end, here are our top five online casinos at a glance, with our findings, ratings and reasonings posted a little further down the page.Best welcome bonus: 10BetBest live casino: BOYLE CasinoBest no wagering bonus: Sky VegasBest for slot games: MrQBest mobile casino: LeoVegas
