Best online casino in the UK? Reddit suggestions for UK slots, blackjack

I'm based in the UK and looking to dive into some online gambling, mainly focusing on slots. I've heard a lot about PlayOJO and its reputation for being fair and transparent, but I'm curious to explore a few other options as well.

What are some other solid online casinos I should check out? I'm particularly interested in platforms that offer a great variety of games, decent bonuses, and reliable customer support. Also, it would be fantastic if the site has a mobile-friendly interface since I like to play on the go.

I know this community tends to have some strong opinions on the best online casinos, so I'd love to hear what you all think. What are the current favorites among UK players? Any personal experiences, both good and bad, would be greatly appreciated.
