What a Jumpman site actually is
Jumpman Gaming Limited holds one remote casino and bingo licence, and runs dozens of brands against it. Each brand has its own name, theme and front end; the platform underneath — the game library, the account system, the promotional machinery, the withdrawal process — is shared. That's a white-label arrangement, and it's entirely legitimate. It just means "trying a different site" often gets you the same games and the same terms in different packaging.
What differs between them, and what doesn't
The parts that genuinely vary between Jumpman brands: the welcome offer model, the theme and the games pushed on the front page, and which promotions are running. The parts that don't: the underlying game library, the withdrawal process, the KYC requirements and the account tools. Our reviews say which is which per brand rather than pretending each site is a world of its own.
Of the 24 we cover, 16 are slots-led and 7 are bingo rooms. Several are newspaper and magazine tie-ins — the masthead is licensed, the casino is Jumpman's.
Why so many of them close
White-label brands are cheap to launch and cheap to retire. When one stops performing, the operator closes it and moves players to a sister site. That's why 15 of the brands we were asked to cover turned out to be shut — and why a "new" site in this family is often a relaunch rather than anything new. The closures are listed above so the question can be answered honestly.
It is not a small pattern. Jumpman Gaming lists 229 domains against its single licence, and across the whole Gambling Commission register more than a third of listed domains are marked inactive — figures we counted ourselves and published, with the method, in ourUK online gambling statistics.
Sister sites and shared accounts
Being on one platform doesn't mean one account: you register separately at each brand, and each welcome offer is claimable once. Bonus abuse terms do generally apply across the family, so opening several accounts to claim several welcomes is the kind of thing that gets winnings voided. Worth knowing before you try it.
