A UKGC-licensed casino from Rootz Ltd
Visit 21Casino →21Casino welcome bonus in United Kingdom
Context for United Kingdom: Since 19 January 2026 the Gambling Commission has capped wagering requirements at 10x the bonus (Social Responsibility Code 5.1.1), and promotions may no longer combine product types such as sports and casino in one offer. If a bonus on this page states 35x, 50x or higher, that figure predates the cap or does not reflect the operator's current UK terms - check the live terms on site, and treat any UK offer still advertising above 10x with caution.
Here is the current 21Casino welcome offer for players in United Kingdom. Bonus terms change and are set by 21Casino for each market — always confirm the live offer on its own site. See every licensed betting site in United Kingdom →
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)
Cons
- Norway offer excluded — unregulated/offshore there due to the state monopoly
- 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. We found no regulatory action against this operator in the sources we consulted, which is a statement about our research rather than about the operator. If you're in the UK, 21Casino's genuine UKGC licensing and no-deposit spins are real positives.
How we rated it
Trust & licensing (30%)8
A real positive: genuine UKGC licensing, one of the strictest Tier-1 regulators, for the UK market. Runs on White Hat Gaming Limited's UKGC account 52894, which carries no regulatory actions on the Commission register - a genuinely clean operator record. Held back from higher only because the register's summary does not itemise domains, so the attribution of this brand to that account rests on specialist directories rather than the register naming it.

Customer support (20%)6.5
No major documented complaint pattern found, consistent with a UKGC-regulated operator.

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. We found no regulatory action against this operator in the sources we consulted, which is a statement about our research rather than about the operator for the UK operation during this research pass.

Who operates this casino?
White Hat Gaming Limited. This brand runs on the White Hat Gaming network - White Hat Gaming Limited, Malta, UK Gambling Commission account 52894. We checked that account on the Commission's own register: 40 domain names recorded and ZERO regulatory actions. That is a clean record, and we state it plainly rather than hunting for an equivalence with the fined operators covered elsewhere in this project. White Hat provides both white-label and fully managed solutions, retaining legal responsibility for UK compliance, player protection and responsible-gambling standards across the brands on its licence - which include 21 Casino, The Grand Ivy, Casimba, Casilando, Playzee, Dream Vegas, Jonny Jackpot, Captain Spins, CasiGo and, since August 2025, 247Bet. Caveat on evidence: the register's summary view does not itemise which domains sit on the account, so the brand-to-licence attribution comes from specialist operator directories rather than from the register naming this brand directly.
