21 Casino Review

21 Casino is a relative new comer to online gaming despite being owned by the well-established Imperium Network Solutions Limited. Imperium, a white label casino site designer who also operates the site, launched it in 2015. Imperium owns a total of five online gaming sites.

21 Casino patrons that reside in the United Kingdom play under gaming licenses and regulations that are governed by the Gambling Commission of Great Britain. The Swede’s play under the Swedish Gambling Authority with all other customers falling under the Maltese Gambling Authority.

Wanting to be as accessible as they can with their customers, they offer Live Chat as well as email support for any questions or concerns. Live chat offers players a sense of confidence in that they can get their concerns addressed right away. Their website translates to 5 different languages with the default currency being the British pound.

As with all casino’s, 21 Casino has a Responsible Gaming Policy. A policy that offers players the opportunity to: place limits on their daily wins and losses; temporarily take a Time Out from the site (short term self-exclusion) or register themselves for long term self-exclusion from all gambling venues within the UK.

21 Casino – Bonuses & Promotions

21 Casino has created a lucrative reward system for players on their site by offering comps for merchandise, game bonuses, cashback rewards and prize draws.

The comping structure is very straightforward. Two comp points for every £10 wagered on the slot machines. Comp points on the tables vary, but they are not as lucrative as the slots. Comp points are available to be redeemed once they have reached 1,000 points. This equals £5.

21 Casino also has a very generous new player Bonus system. They offer a 121% First Deposit Bonus up to £300. These bonuses can also be converted to cash when the industry standard 35x wagering requirements are met. Bonuses are only valid for a limited time once you have received them.

Deposits made through Neteller and/or Skrill do not qualify for many of the player bonuses. New players also receive 21 free spins on the Starburst machine even before they have made their first deposit. One thing that 21 Casino does offer its players is Play for Fun on many of their games. This is where you can play for free with the same RTP (Return to Player) as when playing for cash.

Another promotion that 21 Casino does well, is they offer daily bonuses which are linked to certain machines. Bonuses are only available for slot machines.

21 Casino – Withdrawal Policy

Withdrawing funds from 21 Casino takes longer than most other sites as they have a longer in house processing time. They do have a large selection of payment methods for depositing money to your site account from many third party money cards. Most players don’t mind the extra waiting time as the perks they offer make up for this minor inconvenience. 

21 Casino – Games

21 Casino is very limited in the selection of table games that they offer. With only 19 different games there is very little variety from the standard casino games.

Their draw is definitely from the variety of slot machines they offer. Incorporating games from many of the industry leaders, they definitely offer their slot players a plethora of machines to choose from. The majority of the games on the 21 Casino site have been created by online gaming industry leaders such as NetEnt, Microgaming, Evolution Gaming and landbased based machine giant Artisocrat.

With over 200 machines to choose from, there is no chance of boredom from lack of selection. They also feature more than 25 progressive slot machines and a selection of video poker machines.

All of the standard casino live dealer games can be played at 21 Casino - Blackjack, Roulette, Caribbean Stud Poker , Three Card Poker, Texas Hold’em Bonus, Dragon Tiger, Football Studio, Lightning Roulette, Dream Catcher Wheel, Baccarat, Casino Hold’em.

Because 21 Casino wants to offer their patrons the best possible authentic gaming experience, they made a conscious effort to keep the live table games true to their roots.

Casino – Mobile App

Playing at 21 Casino while out and about is easy when using their mobile apps. Once you have your account set up, you simply need to log into it through the app. Apps are only available through the 21 Casino website for all your Apple and Android devices.

The 21 Casino site itself is very easy to navigate. There are seven active tabs that link to each of the different game categories: Popular; Table; New; Jackpot; Live; Fun; Slots

Players can also scroll through games by their creators. The large sized thumbnails make it easy to spot your favourite games as you scroll down each page.

21 Casino – Licenсe and Regulations

21 Casino uses the latest SSL encryption software from RapidSSL. Their technology focuses on keeping all transactions between servers and public web browsers safe.

21 Casino takes pride in not putting their customer’s data at risk by keeping dormant accounts on their system. Any account that has had no activity for 12 months will be sent an email requesting they log in to keep their account active. These email requests are sent out to the account owner monthly until there is activity on the account or the account is formally closed by 21 Casino. (see T&C)

All accounts held by residents of the United Kingdom will have their account closed after 13 months of inactivity, with any funds remaining in the account being donated to charities that promote Responsible Gambling.

All games featured on the 21 Casino website are subject to independent RTP audits by eCOGRA.


Even though 21 Casino has only been around for less than five years, they have not wasted any time in establishing themselves as a casino that likes to reward its loyal players. With a more than generous Reward and Bonus system, they have quickly moved up the ranks as a player favourite. Being able to play for free is a welcome treat for players.
