I feel your pain. Things do seem very different now post Covid in the online world. Frequently, like yourself I get bonus round that pay maybe 50x if I’m lucky, like you I’ve had £0.00 in a bonus round as well, but they tend to come from Nolimit city games like Fire in The Hole or Deadwood RIP – personally I think a bonus round should have 100x minimum returns given how much you usually have to pay to get the fuckers in the first place, but the slot companies obviously disagree with me. I’ve had some better returns on one or two Elk games such as Buffalo Toro and I still try Blueprint’s Return of Kong Megaways, but I gave up on Primal which used to be good, but now even after 30 spins from retriggers if you’re lucky enough to get a bonus round you usually just get the bonus guarantee – so yeah, seems if you want to play slots in the UK these days best get used to a non lubricated fist up your arse and in your wallet!
