21.co.uk review

What it is

21.co.uk puts its live casino first. Alongside the usual roulette, blackjack and game shows it has a section of exclusive tables, and a “21.co.uk Exclusives” games category. Slots, Slingo, bingo and instant-win games make up the rest.

You can play in a browser or through apps on the App Store and Google Play.

Licence and operator

21.co.uk is run by LeoVegas Gaming PLC under Gambling Commission account 39198, and the domain 21.co.uk is listed as active on the public register.

Payments

LeoVegas lists Visa, Mastercard, Instant Transfer and PayPal for 21.co.uk. Debit cards only. 21.co.uk says any problems with withdrawals should go to its customer support team first, which is also the first step under the Gambling Commission’s complaints process.

Safer gambling tools

21.co.uk points players to deposit limits, breaks and self-exclusion on its safer gambling page. Under LeoVegas’s group policy, self-exclusion here also covers the other five UK brands.

Who it may suit

Adults who mostly play live dealer games. Live casino stakes are not covered by the online slots stake limit, so setting your own deposit or loss limit matters more here.

What we have not included

We do not quote welcome offers, game counts or payout speeds. Offers change often and must be read with their full terms on the operator’s site; counts and speeds are the operator’s own estimates. Before you sign up, read the brand’s terms and check that any offer’s wagering requirement is no more than 10 times — the legal maximum in Great Britain since January 2026.
