Frequently Asked Questions
What are Casumo sister sites?
Casumo sister sites are other online casinos owned and operated by Casumo Services Ltd, the same company that runs Casumo. They share a licence holder and usually the same payments, support and games platform.
Who owns Casumo?
Casumo is operated by Casumo Services Ltd, which also runs the sister brands listed on this page under the same UK Gambling Commission licensing group.
Can I claim a welcome bonus at every Casumo sister site?
Usually not. Welcome offers are typically limited to one per person per operator network, so claiming at Casumo can make you ineligible for the same offer at its sisters. Always read each site terms.
Are Casumo sister sites safe and UK licensed?
Yes – every sister site we list must hold a valid UKGC licence and be GAMSTOP-registered. We re-verify licensing before each update.
