What these licences mean for you

Players in Great Britain get UK rules on identity checks, safer-gambling tools and complaints. GamStop self-exclusion covers all UK-licensed online sites. Self-exclusion: GamStop.
An Alderney licence is a well-established Channel Islands licence. It does not replace the licence of your own country: national self-exclusion registers cover only sites licensed in that country.

About Jumpman Gaming

Alderney-based bingo and slots network and the largest 'sister-site' factory in this batch: its UK register entry lists 19 own active domains, 84 inactive ones and 129 white-label domains. Brands share one platform, one account system rules and one compliance function, so self-exclusion problems across sites were part of a 2022 UK regulatory settlement.
