21Bets is known as a popular UK sports betting site and the casino is tied in to the sportsbook. Launched in 2016, 21Bets is run by FSB Technology (UK) Ltd, the power behind Genting Bet, GoWager and Dafabet. 21Bet is also the official betting partner of Wolverhampton Warriors FC, otherwise known as the Wolves so they have plenty of clout in the betting industry.

Because it’s a new online casino, 21Bets is still relatively unknown but it does show a lot of promise, especially for players who enjoy a bet or two as well as their online casino games. The excellent design is a real standout feature of this site and it uses the latest technology to provide a top quality gaming experience for its players.

Licenced by the UK Gambling Commission, 21Bets is trustworthy and reputable and it goes to great lengths to protect its players. Using SSL technology, all transactions are encrypted so you won’t have to worry about your personal details falling into the wrong hands. Additionally, 21Bets is independently audited so you can be sure their random number generators are fair and the casino acts in a manner that is generally trustworthy and reputable.

21Bets is a great choice for online casino players who love to play slots as it features a great range from Microgaming including a number of progressive jackpots. There are also a few games from NetEnt and Thunderkick to vary it up a bit but the majority of the casino site is run on Microgaming software.

Customer support is excellent here with a variety of different ways of getting in touch if you have an issue and responsive customer support agents on hand from 8am to after midnight. The only real downside to this casino is the limited deposit and withdrawal options. Players can only use card to make deposits and withdrawals which does limit things somewhat, especially if you’re privacy conscious and prefer not to show casino transactions on your credit card statements.

If you’re a sports betting fan who likes an occasional flutter on the slots or you’re keen to play the odd hand of blackjack or poker online, you’ll love 21Bets Casino. It offers plenty of variety and a strong selection of casino and table games not to mention some worthwhile promotions.

Welcome Casino Bonus 

21Bets offers a generous welcome bonus for new players, in the form of a 100% deposit match worth up to £300 when you sign up and make your first deposit of at least £10. Unlike many other sportsbook/casino sites, this offer is open to existing sportsbook customers – you just have to be a new player at the casino to qualify.

The wagering requirements for this bonus are high at 70x including the deposit amount and the initial bonus amount given. Players have 30 days in which to meet the wagering requirements of their bonus or the funds will be forfeited from their account.

There are also certain game contributions to be aware of when playing through your welcome bonus. While you still have an active bonus you will have a staking maximum of £10 in any single bet and regardless of your winnings, you will only be able to take a maximum of £10,000 from your bonus.

Game contributions are as follows:

  • Slots (except for progressive slots) and scratch cards – 100%
  • Roulette and blackjack – 10%
  • Poker – 5%
  • Progressive slots and baccarat – 0%

Clearly this is a bonus that’s intended for slots players, but given the high wagering requirements and the fact that you can’t play through your bonus on progressive games, you’re going to have to play a lot of slots to be able to meet the high wagering requirements.

How to Get the Bonus

  1. Sign up for an account at 21Bet
  2. Opt in to the welcome bonus
  3. Make a qualifying deposit of at least £10
  4. Your bonus will be credited automatically to your account.

Deposits/ Withdrawals

21Bet is limited when it comes to making deposits and withdrawals. Unlike most other online casinos out there, players are limited to credit and debit cards. 21Bet only accepts Visa, MasterCard, Visa Debit, Visa Electron and Maestro as payment methods. This is unfortunate, as it doesn’t allow players to use more secure methods of payment including e-wallets.

Once you have made a deposit at 21Bet your money will be available more or less immediately, while withdrawals will take a while longer to arrive in your account. The minimum withdrawal amount is £10 and the maximum is £5000 and you must withdraw your funds on to the same card as you used to deposit with.

While 21Bet doesn’t charge any fees for making a withdrawal, your bank or credit card issuer may. Withdrawals should be in your account within three to five days pending a 24-hour processing period.
