Bonuses & Promotions

The 21.co.uk Welcome Offer

  • 1st Deposit: 100% Up To £50 + £6 In Live Casino Chips
  • Minimum Deposit: £10
  • Promo Code: n/a
  • Wagering requirement: 40x

New players at 21.co.uk can enjoy a very different sort of Welcome Bonus.

When you open a new account and make a first deposit of at least £10, which you then wager 40x on live dealer games, you will receive a 100% match on your initial deposit (up to £50), as well as £6 in chips for play in the 21.co.uk live casino over the course of three days on selected games (£2 per day).

You have 7 days after registering for a new account to claim the introductory offer, and then seven days in which to wager 40x your deposit amount.

Make sure to opt in if you want to claim the Welcome Bonus, via the My Offers page. Winnings from each £2 chip are capped at £50, with bonus winnings paid in cash.

This is an unusual sign up deal, as it is directed at live dealer games rather than slots, so it won’t suit everyone, but if you enjoy live blackjack or roulette, this is a unique offer that gives you the chance to play some first class live casino games.
