There are many slot-related websites available to UK users, so I think it makes sense to compare them using the same criteria. Game selection, navigation and mobile usability are three things I would look at first. Double Bubble slot can be reviewed alongside other British-facing slots platforms. I would explore the catalogue to see which types of games are available and whether it is easy to find particular titles. Information about individual games can also be useful when comparing different options. After checking the gaming side, I would look at registration, verification and payment conditions before considering any promotional offer.
