Klirr Casino Review

When a company pulls of something few others can, it’s always impressive and Klirr is no exception. Going live in 2020 and owned by the Mill Adventure Limited, this platform is what’s known as a “pay ‘N play” casino. In layman’s terms, that means you don’t have to go through the usual registration process to enjoy 1,000+ casino games.

If that’s not enough to tempt you, Klirr also gives new customers up to €100 when they make their first deposit. It’s currently available in Sweden and Finland but we expect it to go live elsewhere in the future. So, if you’re ready to learn about this innovative offering, let’s get on with our Klirr Casino review.

Casino Bonus

Klirr doesn’t need a welcome bonus to stand out from the crowd but, luckily for you, it still has one!

Klirr Casino Welcome Bonus & Free Spins

You can get up to €100 as a newbie when you join this innovative online casino. Unfortunately, this deal only applies to players living in Finland or Sweden. We’ll explain why that’s the case later in this Klirr Casino review. For now, just know that its opening offer has limited availability.

The good news is that it probably won’t be that way for long. This is a fantastic new online casino and we expect it to be available in other countries soon. So with that in mind, here’s what you look forward to as a new customer:

  • The Klirr Casino welcome bonus = 100% first deposit match up to €100.
  • Minimum deposit required = €20.
  • Wagering requirements = 25X bonus + deposit amount.
  • Wagering period = 14 days.
  • Max bet during wagering period = €5.

This is a small but well-appointed promotions for two reasons. Firstly, the bonus cap means that you won’t be forced to hit unrealistic wagering targets. Secondly, there are plenty of games that can help clear the bonus. Slots have a 100% contribution weighting and there are more than 900 spinners to choose from. Therefore, you shouldn’t have too many issues claiming the Klirr Casino first deposit bonus.

How do you use Klirr? Here’s how…

How to Join

Klirr is what’s known in the business as a “pay ‘N play” online casino. That means you can literally make one deposit and starting betting in seconds. This is possible because the one and only payment option is Trustly. This payment method links to a special ID generated by your bank. That means Klirr doesn’t have to go through the same verification process as other online casinos.

Basically, Trustly verifies your identity using your BankID. This means Klirr can be confident you’re a legit user and, therefore, roll its deposit and registration processes into one action. To put it another way, you can make a deposit and create an account at the same time. This makes Klirr easy to join and, in turn, allows you to “pay ‘N play”.

Klirr.com is currently available in Sweden and Finland. However, as its reputation spreads across the industry, don’t be surprised if it launches in other countries. For those that can join, here’s how to create an account at Klirr Online Casino:

  1. Click our Klirr.com link.
  2. Hit “Play Now” and enter a deposit amount (at least €20).
  3. Play any game of your choice.

Deposits and Withdrawals

You don’t have to waste time deciding which payment method you’re going to use at Klirr because there’s only one. Trustly is the way you pay to play. Even though choice is great, we like that fact Trustly is the only option. For starters, we know that it’s extremely secure. Secondly, it’s efficient and withdrawals can be processed within a few hours.

Thirdly, and most importantly, Trustly allows Klirr to be a pay ‘N play casino. It verifies your identity via banking details. That not only speeds up the registration process but makes fraud virtually impossible. In other words, the KYC (Know Your Customer) standards at Klirr Casino are some of the best in the business.

Casino Games

Klirr isn’t just a novel way to play online casino games without going through a traditional registration process. Yes, that’s one of its major selling points, but it’s not the only one. Once you start browsing its library of games, you’ll see that it’s packed with options. In fact, during our Klirr casino review, we counted more than 1,000 games!

That’s impressive by anyone’s standards but the good news doesn’t stop there. The lobby is as big on quality as it is quantity. Topping the list of software providers is Yggdrasil, along with other industry leaders such as NetEnt, Play’n Go and Red Tiger Gaming. Also adding some spice to the mix is Big Time Gaming and its patented technology, Megaways.

Finally, to ensure there are games for every preference, genre and style, you’ll find top offerings from Leander, Relax Gaming, Quickspin and many more. In short, if it’s a hit, you’ll find it inside Klirr.com. 

In terms of what you can play, Klirr is crammed with a slick selection of slots. From video slots like Reactoonz and Gonzo’s Quest to progressive jackpot games and Megaways marvels, there are hundreds of ways to spin. If you don’t fancy that, Klirr Casino also offers blackjack, roulette, baccarat, live games, video poker, keno and even bingo. That’s a great line-up and it’s made all the more impressive by the fact you can pay and play for cash prizes in seconds.

Some of the best games at Klirr Casino are:

Casino Experience

What’s it like to play at Klirr Casino? Let’s take a look…

Playing Klirr Casino on Desktop and Mobile

We have to be honest and say that Klirr was a little slow to load at times. This may have been a connection issue on our end. However, the app is quite resource-heavy, so make sure your device is up to the task.

Assuming it is, the payoff is worth it. The black and red colour scheme gives Klirr a dark and mysterious vibe. For an online casino that’s aiming to shake things up with a novel pay and play system, the styling works extremely well.

Scrolling through the site, we were pleased to see highlight carousels used to good effect. Instead of listing anything and everything on the homepage, games are put into categories. These categories are used to divide up the page. This set-up allows you to get an overview of what Klirr has to offer and, in turn, branch off into your preferred categories with ease.

Customer Communication

Klirr’s unintrusive ethos is present in everything it does. If you want email updates, you can have them. If not, no problem.

Klirr Casino Customer Support

There have been some complaints that the Klirr support team isn’t as responsive as it could be. We didn’t experience any issues but some customers have said that response times are inconsistent. In our opinion, this is to be expected from a fledging online casino. Klirr only launched in 2020 so, given more time, we’d expect customer service to improve.

If you do need any help, you can contact Klirr support via the following methods:

  • Live Chat
  • Email: support(at)klirr.com


  • Is Klirr Casino legal? Arrow

    Yes. This operator is licensed and regulated by the Malta Gaming Authority (MGA) as well as the Swedish Gambling Authority. This means it’s active in Finland and Sweden (true at the time of writing). However, an MGA licence will allow Klirr to launch in other countries in the future.   

  • Can I play for real money at Klirr Casino? Arrow

    Yes. As well as free demo games, you can win cash prizes when you play from as little as €0.01 per round. The minimum deposit at Klirr is €20 and you can withdraw up to €25,000 per month.

  • What are the best games at Klirr Casino? Arrow

    There are too many to games at Krill to pick just one. This is one of the best desktop and mobile casino sites for those that love instant action. To match this vibe, we’d suggest taking a quick spin on Yggdrasil slots and those featuring Megaways.

Expert Casino Review of Klirr Casino

The world of online casino gaming is changing. Platforms such as Guts Xpress and Klirr are making it easier to jump straight into the action. Importantly, this ability to pay and play doesn’t come at the expense of quality at Klirr.

The site and mobile app are both impressive both in their design and layout. Then, of course, there’s the fact you can play more than 1,000 casino games and get up to €100 as a new customer. For all of these reasons, plus the fact you can pay and play, we recommend giving Krill Online Casino a try.
