About 21 UK Casino

The Casino holds a licence with the United Kingdom Gambling Commission and has a vast assortment of games, from online slots to table games and live Casino. The site is modern looking, with the game selections running down the left of the webpage, making it easy to navigate and choose categories. The offers are prominent at the top of the homepage so customers can clearly see what promotions are up for grabs. Customers can access the online Casino on a desktop, tablet or mobile phone. A designated app for 21 is available to Apple and Android users so players can enjoy online betting on the go.

71/100 points (3.6/5)

21 UK Casino, part of LeoVegas Gaming PLC's family of UK brands, positions itself as a live casino specialist while still carrying thousands of slots, tables and Slingo titles. The live dealer suite, built largely on Playtech studios, is a genuine strength, and the welcome package aimed at that section is wagering free, a rare and welcome touch. Backed by a long established, well capitalised licence holder, the platform feels polished with fast loading pages and a dedicated mobile app on both major operating systems. Ongoing promotions exist but are not as frequent as at some rivals. Payment options are mainstream and withdrawals are generally processed within a couple of days, though some users report extended waits tied to verification. Customer service runs around the clock. Overall this is a trustworthy, well built casino that particularly suits players who enjoy live dealer games over slot heavy sites.
