Slots sites in uk not on gamstop, any new name to add to the list?

[SimbadThePirate]

been exploring new slot sites in the UK that aren't on GamStop. Came across GoldenBet, Bass Win Casino, and Golden Mister, they seem promising.
Anyone tried these or have other recommendations?

Goldenbet is a decent shout, but Mister? Sounds sketchy to me. Bass Win Casino has been making rounds tho—anyone got some wins there?
