Pros
- Genuine UKGC licence — a Tier-1, strictly-enforced regulator
- No-deposit free spins plus a strong 121% deposit match
- Reasonable wagering requirements (35x bonus, 10x spins)
- No major documented scandal found in this research pass
Cons

- Limited to the UK in this review's real-market coverage
- Newer, less internationally recognised brand than larger UK operators
Our verdict
21Casino, operated by Rootz Ltd, is genuinely licensed by the UK Gambling Commission (UKGC) — one of the strictest Tier-1 regulators — for the UK market. New UK players 18+ get 10 no-deposit free spins on Book of Dead just for registering, plus a 121% deposit match up to 100 GBP on a deposit of 10 GBP or more, with a reasonable 35x wagering requirement on the bonus and 10x on spin winnings. 21Casino also targets Norway, but that offer is excluded from this review: Norway runs a state gambling monopoly (Norsk Tipping/Norsk Rikstoto), so 21Casino's Norway-facing site operates unregulated and offshore rather than under local licence. No major independently-documented scandal was found during this research pass. If you're in the UK, 21Casino's genuine UKGC licensing and no-deposit spins are real positives.

About 21Casino
21Casino is a casino operated by Rootz Ltd, genuinely licensed by the UK Gambling Commission (UKGC) for the UK market. New UK players aged 18+ get 10 no-deposit free spins on Book of Dead simply for registering, plus a 121% match on their first deposit up to 100 GBP (minimum deposit 10 GBP), with a 35x wagering requirement on the deposit bonus and a lighter 10x wagering on spin winnings. This review excludes 21Casino's Norway-facing offer: Norway operates a state gambling monopoly (Norsk Tipping for most gambling, Norsk Rikstoto for horse racing), so non-state brands like 21Casino operate there unregulated and offshore rather than under a local licence — a genuine, confirmed legal-market exclusion. No major independently-documented scandal was found for the UK operation during this research pass.
