What was Good?
Came across this lovely online and mobile casino called 21 Casino a while ago. Great looks and games to choose from: there were lots of them from numerous providers. A 121% unlimited welcome bonus was the start of a series of bonuses. Played my favorite NetEnt slots, and there were live games and jackpots too. So many games and so much fun, all in a completely secure environment. I deposited €30 and made some off it too! Am thinking I must come here again.
What was Bad?
The one thing that got me was the lack of phone support. I had to engage in live chat, which was fine. But talking your problem out loud always works better, in my experience. Get them a phone, somebody!

What was Good?
21 Casino was a whole lot of fun to play at. The great looks are completely backed up by an amazing portfolio of games. This is a multi-platform casino that is powered by the White Hat Gaming platform; that is why you get hundreds of games from more than 15 of the top casino software providers. That is not all; there is a mobile casino as well, and live dealer casino games from top names like Evolution Gaming and Ezugi. I love Gonzo’s Quest and was thrilled to be able to play this cool slot when I was here.

The welcome bonus and other promotions made it worth my while: imagine a 121% bonus on whatever you deposit! I deposited a moderate €50 and had more than enough to play with, and ended up winning some as well. An industry average wagering requirement of 35x meant withdrawing winnings was not too much of a headache. Searching for games was easy and I had a quick peek at the jackpots available; they were impressive, though I did not give any of them a shot.

This is a completely secure casino from Caddell Limited NV and uses industry-standard security technology including 12-bit SSL encryption. I was not worried about security anyway since the reputation of the casino operator preceded it, but it was good to see the measures they took. Easy and quick deposits and excellent support through live chat made the gaming experience more enjoyable.
What was Bad?
The one thing that struck me was the amount of time it took to get my winnings out. The official withdrawal time post approval is supposed to be 2 days but it took way more than that. I wish these guys take care of this because it puts a real dampener on an otherwise great time.

The new trend in the online casino industry has been multi-platform casinos; casinos that use software from multiple providers to give players an experience they have never had earlier. There are hundreds of games – sometimes more than a thousand – to choose from, all provided by some of the best casino software providers in the industry, cool promotions, and so much more. I wanted to check out what the experience of playing at one of these casinos was like and therefore landed up at 21 Casino.

21 Casino is a great place to be at. The casino looks great and has a fabulous interface that guarantees seamless navigation. It is powered by White Hat Gaming, which means you get an amazing game range with a massive selection of high quality slots and other games from more than 15 top-notch providers. I like slots from NetEnt and Quickspin, and got a good opportunity to play them without having to jump from one casino to another. There are more than 25 exciting jackpots and also live casino games from Evolution Gaming, Ezugi, NetEnt, and others. This casino is owned by Caddell Limited NV and licensed by Curacao eGaming and the UKGC.

There are a number of cool features at 21 Casumo, but what I liked most apart from the games and promotions was the sort feature: it allowed me to sort games by popularity, software provider, and also RTP; that last parameter is not something I have seen at casinos earlier. The bonus for new players was exciting as there is no upper limit to the bonus you can get depending on your deposit: a matching bonus of 121% is what you get for whatever you deposit. And you get 10 free spins on any NetEnt slot that you want to spin.

Great promotions, excellent security measures – the certification by GeoTrust is proof of that – and the availability of a mobile casino with a significantly large collection of games makes 21 Casino a place to visit frequently. Further bolstering that image is the wagering requirement for the bonuses, which is a standard 35x.
What was Bad?
With such a brilliant offering, there is not much to not like about 21 Casino. The only two things that I can comment on as something that could be better are the withdrawal times and the lack of phone-based support. I am a phone guy and not too much into chatting or mailing; so for me that would be a big negative, but in general I guess it is one of those things that you just have to take in, given that everything else at the casino is magnificent.

What was Good?
My recent experience at 21 casino is something I thought I should write about because it left me with mixed feelings. I loved the overall feel and vibe of the casino; it looks good and has a superb selection of games from leading casino software providers who are on the White Hat Gaming platform. The promotions are great too, and the support for a large number of payment methods makes depositing and withdrawing funds easy.
What was Bad?
There is no phone support, and that just didn’t sit well with me because I love contacting support over phone – easier to talk than to text. What got me was the withdrawal dilemma; it takes a long time compared to some of the other newer casinos and that is really frustrating. It is my money after all that I put in; the casino is not giving me money for free.

If you are looking for a good online casino – one that looks great, has good games, and bonuses for s day and had a very satisfactory gambling experience. In fact it was so good and nice I decided to write about it … thanks to 21 casino for a great time there.

This is a casino from the stables of Caddell Limited NV, a company that has a number of good looking and popular online casinos, and is operated by Imperium Network Solutions Ltd. It was founded in 2015 and operates with licenses from the Malta Gaming Authority and the UKGC.

It is powered by the White Hat Gaming platform, which means you get games from almost all the providers who are part of this amazing gaming platform. I was able to zero in on my favourite NetEnt slots, and there are tons of others as well from other providers including Microgaming, Amaya, Quickspin, Thunderkick, Genesis Gaming, and others. There are hundreds of games to choose from, including a large cache of top-class slots, table and card games, video poker, bingo, live dealer games, and also jackpot games.

There is a mobile version as well that looks as good and classy as the desktop version and is compatible with the Android and iOS platforms. All in all, a great secondary option to have, and definitely a must-visit if you are a mobile casino fan. You get a good collection of games too, and the promotions at the desktop casino are available on the mobile casino as well.

These include the cool welcome bonus of 121% on the first deposit with no limitation on the maximum match amount and 10 bonus spins to go with it. Other bonuses at both the versions include the 21% up to £210 Hangover Bonus, and up to 50 bonus spins on Starburst, Stickers, Fruit Shop, Lights, and Aloha! Cluster Pays with the Stairway Bonus, besides access to the loyalty program and the VIP Club.
What was Bad?
There are not too many things that seemed off at this casino. The first is the lack of phone support. The second and more important one, I feel, is the long verification process; at a time when there are casinos offering instant withdrawals within 24 hours, having a 2-day verification process doesn’t make sense.

21 Casino is an amazing place to be at; that in brief is my feedback on this casino. And mind you, I have played at quite a few of these online casinos over the years. The casino looks great – you will not love the look if you are into bright and vibrant colours or funny graphics on the landing page. The colour scheme is grey and encases a soberly colourful display area that showcases the prime bonuses on offer.

The casino was not just about the looks; it had a superb range of games from some of the best casino software providers around. It is powered by the White Hat Gaming platform, which has on it providers of the calibre of NetEnt, Microgaming, Leander, Quickspin, and many others.

There are over 20 providers offering their games at this casino, and that makes for a good spread of hundreds of games including slots – classic slots and video slots, table games like blackjack, roulette, poker, and other games for regular players as well as high rollers, jackpot games including the biggest of them all – Mega Moolah, video poker, bingo, scratch cards, virtual betting, and also live dealer games. That makes for a pretty comprehensive spread of game: there is something for everybody here.

The casino has a superb range of bonuses as well that I just loved. There was a stupendous unlimited welcome bonus of 121% on my deposit and 10 free spins that I could use to play any NetEnt slot of my choice. There are also daily bonuses to look out for and the rewards vary, from match bonuses and free spins to gifts and giveaways. And if that is not enough, there is also the cool Hangover bonus, which gives you a 21% match bonus up to £210 every Monday and Tuesday.

All bonuses come with wagering requirements and other terms and conditions that you have to fulfil to be able to redeem winnings from them. The standard wagering requirement here is 35x the bonus amount. From the bonuses we move to the payments: I was happy to find a good spread of payment methods supported by the casino including Visa Debit, my standard payment method. Other methods supported include Visa, MasterCard, and Maestro credit cards, Trustly, Sofort, NETeller, Skrill, PaySafeCard, and also bank wire.

The casino also has a cool mobile version that has most of the games available at the desktop version. The mobile casino is compatible with both Android and iOS platforms, which means I was able to play my favourite slot, Immortal Romance, directly from my Android smartphone. Like the desktop casino, the mobile version too is available in instant play mode only. Customer support was great too and I was able to get in touch with a support team member through live chat. The other option you have is e-mail.

This casino is owned by Caddell Limited NV and operated by Imperium Network Solutions Ltd. It is licensed and regulated by the Malta Gaming Authority and the United Kingdom Gambling Commission (UKGC), and also Curacao eGaming.
What was Bad?
This is a great casino to be at. I only wish they had phone support as well. Haven’t won much here but it has overall been a satisfactory experience.
