Whether or not you’re new to gambling, there are many things you must think about when choosing where to play. We evaluate an operator’s game choices, mobile play, safety features and customer support. This gives us a numerical rating perfect for comparing sites. So, how does 21 Casino stack up?

The 21 Casino Games Portfolio

First up in our review are the 21 Casino games. We evaluate every operator’s game collection on quality and variety, so you’re able to choose from the best games on the market. 21 Casino doesn’t disappoint as it features over 1,500 titles from the world’s leading developers.

The Best 21 Casino Games

In this immense collection of games are all the casino hits. You’ll find roulette, blackjack and slots, plus popular niche categories like slingo and scratch cards. In total, we counted 1,675 games at the 21 Casino online casino, well above the industry standard.

Additionally, you’ll find scores of live dealer options, which we go into detail about in the live games section of this article. Unfortunately, in the throng of 21 Casino games are only two video poker titles, so head over to our best video poker casinos page if that’s your game.

The Most Popular Games at 21 Casino
Slots (1,005) Roulette (9) Blackjack (15) Table Games (10) Video Poker (2)
Bonanza European Roulette Classic Blackjack Gold DJ Wild Stud Poker All Aces
Starburst Double Ball Roulette Atlantic City Blackjack Mississippi Stud Jacks or Better
Immortal Romance Roulette Advanced European Blackjack Gold 3D Baccarat
Game of Thrones 243 Roulette Nouveau Perfect Pairs Blackjack 3 Hand Casino Hold’em
Reactoonz 3D European Roulette Lucky Blackjack Casino War
Gonzo’s Quest French Roulette 21 Plus 3 Blackjack 100 Bit Dice

We didn’t find much to complain about during our 21 Casino review as far as slots are concerned. It has almost every popular title we could think of, and a solid number of jackpots to boot. If you’re searching for something new, check out this list of our favourite games:

What really blew us away is the sheer number of software developers the operator stocks its games from. Over 100 of the world’s top casino game providers license their titles here, which is lightyears beyond most sites.

The 21 Casino games portfolio features over 100 titles from popular developer NetEnt, so ensure that you read our NetEnt review. In the article, we put its games through their paces and explain why we feel it’s one of the best software companies around.

The Live Dealer Choices

Like most operators nowadays, the 21 Casino online casino features live table games. This popular playstyle lets you socialise with the dealer and other players while you gamble, taking immersion to the next level. Many players also enjoy not being at the mercy of a random number generator.

The live games section features software from Evolution Gaming, a leading developer in this area. To get an understanding of just how popular this provider is, pop over to our list of the top live casinos, where you’ll find that most feature Evolution games.

The Mobile Gaming Experience

Something that caught our eye at the 21 Casino online casino is how easy it is to get in on the action from your smartphone or tablet. You play directly in your device’s browser, which eliminates the burden of an app for both you and the operator.

21 Casino Mobile Gaming Amazing casino action right at your fingertips – anywhere, anytime.
£300 Welcome Bonus
Full T&Cs apply. 18+. New players only. Min deposit £10. Bonus funds are 121% up to £300 and separate to Cash funds. 35x bonus wagering requirements apply. Only bonus funds count towards wagering requirement. £5 max. bet with bonus. Bonus funds must be used within 30 days, otherwise any unused shall be removed. Terms Apply. BeGambleAware.org

While we always enjoy a great instant-play operator, some people do prefer gambling through an app as it can streamline the experience when done properly. We’ve put together a list of the best mobile casinos if you enjoy this method of play.

Table Limits That Won’t Break the Bank

When evaluating casinos there is another important aspect to keep in mind – how much it costs to make bets. The 21 Casino online casino features a decent spread of table limits, but don’t expect to become a super high roller as the largest bet for an RNG game is £1,500 on roulette.

This operator definitely had those of us on a budget in mind when selecting its game portfolio, with minimum bets of 1p on slots and £1 on table games, though this varies depending on the title. Check out our 21 Casino games section of this review for our favourites.

21 Casino Payout Rates

In addition to knowing how much it will cost to play, every gambler wants to know how much they can win. While it’s impossible to know if a win is coming, you can know a game’s return to player (RTP) rate.

This number is the percentage of funds wagered returned to players over an extended period of play and won’t reflect an individual player’s experience at a given game. You can see 21 Casino payout rates in the table below.

Payout Rates of the Different Casino Games
  • .
  • Classic Slots 91.62 - 98.00%
  • Video Slots 88.00 - 99.00%
  • Roulette 94.74 - 98.65%
  • Blackjack 99.00 - 99.75%
  • Table Games 96.38 - 99.33%
  • Video Poker 99.56 - 99.92%
  • Scratch Cards* 76.67 - 96.00%
  • Arcade Games* 00.00 - 00.00%
  • ..
  • .....
  • RTP (%)

A common misconception is that these numbers are dictated by the casino, but it’s the developer’s call. All casino games use random number generators, so the payout rate is built into the code. Titles are then vetted by industry-recognised third-party auditors, so the numbers shown can be trusted.

Ultimately the reverse of the house edge, RTP is most helpful when evaluating two similar games. If you can’t decide which title to try, we recommend going for the one with the higher RTP. This gives you the best chance to stretch your bankroll.

The 21 Casino User Interface

Though some may find a casino’s interface unimportant, it’s still a great point for comparison. The 21 Casino online casino has a streamlined interface, which gives a brief overview of the games. Simply mouse over a title to see things like RTP and how many pay lines it has.

The cashier button is in the top right corner of the site, allowing for quick, easy access. The entire site loads quite rapidly, which is also a significant plus. It’s never fun spending more time navigating menus than sitting at the tables! Our 21 Casino review gives full marks here.

As is the trend lately, there is no software to download at the 21 Casino online casino. You can play all the games instantly in a compatible browser. This reduces the burden on the operator and you avoid waiting for the download to finish before you place your bets.

Though we always enjoy a no download casino, we realise some of our readers enjoy the added functionality a software client can offer. We recommend reading our PokerStars review if you want a full-service software client.

Over 100 of the world’s leading casino game creators supply the 21 Casino software. Most of them provide slots, but heavyweight provider NetEnt contributes most of the table games. If you’d like to learn more about NetEnt and why it’s a leading developer, read our NetEnt review.

The 21 Casino online casino designers did a great job of achieving their goal of creating a premium casino. The black and gold theme brings this aesthetic together and gives the site a high roller feel. It’s also easy on the eyes, which is good when you’re playing long sessions.

The Lowdown on 21 Casino Ownership

21 Casino is owned and operated by White Hat Gaming, a Maltese company renowned for its stable of websites. In addition to 21 Casino, the group owns some of the leading operators such as Playzee, Grand Ivy and Casimba, all of which we review on this site.

Additional Operator Information

Since 21 Casino is owned by such a successful and well-respected organisation, you can expect it to take care of its players. This operator has implemented deposit limits, activity limitations and self-exclusion protections to help prevent players from developing gambling problems.

Additionally, the site sponsors problem gambling organisations like GAMSTOP and GamCare to help players who may have problems stopping play. If you feel like gambling is negatively affecting your life, we encourage you to reach out to an organisation like GamCare at once for help.

Contacting Customer Service

While it’s never fun doing account maintenance or having technical issues, it’s useful to know how to get in touch with a customer service agent. We include this in our reviews because it helps confirm the dependability and veracity of the site.

The 21 Casino help team is reachable 24/7 via live chat or email. We like the ability to contact someone instantly if the need arises, though we acknowledge some people prefer email. Either way, the support team was friendly and helpful whenever we had questions throughout our 21 Casino review.

If English isn’t your first language, you may be in luck as 21 Casino support agents speak a few other languages, specifically German, Norwegian, Finnish and Swedish. Ideally, we’d like to see more languages represented, though some options are better than none.

Online Security and Safety

When looking for operators, your safety is something you should always keep in mind. Reputable sites will mention somewhere on the webpage or in the terms and conditions the type of security that it implements. Looking for this information is important because it can keep you from being scammed.

Reinforcing the 21 Casino safety measures is 128-bit SSL encryption, certified by RapidSSL. A RapidSSL certificate is a sure-fire signal a site’s transactions are extremely secure. Additionally, the operator features a web security certificate from Amazon, which is another respected brand vouching for the company.

Arguably the strongest signal of a site’s safety is its gambling licences. 21 Casino is licensed by the Gambling Commission (UKGC) under licence number 52894. It’s also licensed in Malta under MGA licence MGA/B2C/370/2017, meaning it meets licensing requirements in two jurisdictions.

Bonus Points Earned

To round out our 21 Casino rating, we examine some extras that make operators good sites to play at. Examples include things like awards, special games or loyalty programmes. Unfortunately, we couldn’t find any awards this operator’s won, but it makes up for that in other areas.

Promotions were the primary area we found greatly improved the 21 Casino online casino. It features a generous welcome bonus and has ongoing offers for existing players. The wagering requirements are fairly average, so if they’re too high for you check our bonuses page for something more budget friendly.

  • Awards.0/3
  • Promotions.3/3
  • Special Games.2/2
  • Loyalty Scheme.1/1
  • Extras.1/1
  • Bonus Points.7

On top of the ongoing promotions, 21 Casino has a loyalty programme where you build up loyalty points for every wager you make. When you have enough, you can turn points into bonus funds to wager again.

Since these are bonus funds and not cash back, they often come with wagering and validity requirements. To avoid any unpleasant surprises, we recommend reading the terms and conditions for all promotions.

21 Casino Review Conclusion

Overall, we enjoyed our time researching for this 21 Casino review. The website is user friendly, features loads of games and has a great customer support team. The standout aspect of it, however, are the 21 Casino payout rates.

It’s rare to find an operator that’s gone through the care to find and stock such high RTP games. Frequently you’ll find operators that feature low RTP catalogues but offer enticing welcome bonuses to drive traffic to their sites. 21 Casino offers both high RTP games and a generous welcome bonus.
