21.co.uk was created in 2012 and owned by LeoVegas Gaming plc. 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.
