21 Casino Bonuses and Promotions

Time moves quickly. It seems like just yesterday 21 Casino launched in the UK with a unique concept. Yet, enough time has passed since that 2015 launch that the site is becoming an increasingly popular UK online casino. 

Even though 21 Casino is already well established, many players may still be unfamiliar with the betting brand and everything it has to offer, including its expertly curated games portfolio and some of the best slots bonuses in the UK

That is where this review of 21 Casino will help. We will guide you through every aspect of the site to help you decide if this is the online casino for you. Below you can read about the 21 Casino bonus, games, customer support and more. 

21 Casino was born from a group of iGaming industry heavyweights who wanted to build a unique online casino - one built on luxury. Since its inception, 21 Casino has carried its dedication to the lavish side of top casinos and continues to focus on elegance. Part of the White Hat Gaming stable of iGaming websites, 21 Casino is part of one of the most reputable groups in the industry.

21 Casino Bonus

When registering as a new player on the site, you’ll have a lucrative casino bonus offer waiting for you. Over the years, 21 Casino has become known for its eye-catching and unique first deposit offer deals. While the specifics of what you can get change from time to time, the online casino often offers a generous deposit match. 

Yet, 21 Casino puts an original twist on the deposit match. Instead of having a round number match bonus (such as 50% or 100%), the site offers a more random percentage (121%, for example), with a max bonus of £300. While this is admittedly a gimmick, it does mean 21 Casino offers a match bonus that is often slightly better than other UK casino sites. 

Furthermore, the requirements for claiming the 21 Casino bonus are quite accessible. For example, a minimum deposit of £10, a 35x wagering requirement, and a £5 max bet during the wagering requirement. But, as always, we recommend reading the T&Cs of the 21 Casino bonus before playing for it. Nonetheless, you can really boost your bankroll from the get-go at 21 Casino. 

21 Casino Live Casino Bonus

When you become a regular at 21 Casino, there is no doubt you’ll spend plenty of time in the quality live dealer section. However, there is currently no 21 Casino bonus that focuses on the live casino. 

21 Casino Sports Bonus

As most operators look to diversify and offer sports betting, casino gaming, and other gambling options on one site, 21 Casino is sticking to its guns. Customers get a complete dedication to the casino experience without the distraction of sports betting markets. Of course, that means there is no sports bonus on the site. 

21 Casino Bingo Bonus

When you drop into the live casino, you will see a couple of online bingo rooms. 21 Casino is also home to several Slingo games and bingo-themed online slot machines, including Slingo Rainbow Riches, Book of Slingo, and Bingo Billions. Yet, you won’t find a specific bingo bonus at 21 Casino. 

21 Casino VIP Programme

There is a loyalty programme and VIP programme available at 21 Casino. The first is a classic rewards system based on how much time and money you spend on the site. As you gather more points and move through levels, you can convert these for bonus funds. Yet, this bonus will be subject to 21 Casino’s standard 35x wagering requirement.

As for the VIP programme, it is more mysterious because it is invite-only. We do know that VIP players get account managers, higher withdrawal limits, and other benefits. However, the specifics of the programme are less known.

21 Casino Safety

We can safely say there is nothing untrustworthy about 21 Casino. To help guarantee its reputability, the site holds a licence with the Malta Gaming Authority (MGA/B2C/370/2017) and the UK Gambling Commission (52894), two of the strictest and most reputable gambling regulators in the world. 

Also, 21 Casino employs cutting edge SSL encryption technology, protecting all financial and personal information on the site. Games on the site go through independent tests to ensure all outcomes are fair and random. Similarly, each payment method you can select on 21 Casino is a major financial brand with the best security measures to protect deposits and withdrawals. That applies to all bank transfers and e-wallets, and this is also one a smaller number of pay by phone bill casinos. Options here include reputable providers like Boku casinos and Payforit. 

All UK players must verify their online casino accounts before cashing out for the first time. While this verification procedure is required under valid gambling regulations, it is also vital in preventing underage gambling, fraud, and money laundering. Thankfully, 21 Casino makes this process straightforward. Simply upload a copy of your photo ID and proof of address, and the site will validate your account as soon as possible. 

21 Casino Customer Support

Any casino that prides itself on luxury must have customer support that goes above and beyond. Luckily, 21 Casino meets those expectations with customer support that ticks every box. We really love the FAQ section, which offers plenty of information but is easy to use. 

Alternatively, live chat is the best option if you want to make direct contact. You get 24/7 live support, and connection times are the best around. You can expect to speak with an agent within seconds, and all interactions are professional, polite and helpful. If you have more general queries, the email support turns around questions within a couple of hours.
