Klirr Casino - Video Review

Klirr Casino Review

Klirr is a brand new online casino recently launched in 2020 with a library of more than 1000 different games. It is owned and operated by The Mill Adventure Limited, a company that runs one other brand. The casino accepts only customers from Sweden and Finland, and it’s strictly Pay N Play, meaning that they can skip the registration process and instantly start to play any of the games by using Trustly to deposit.

Deposit €100 and Play with €200

Unlike the other Pay N Play casinos, Klirr offers a matching Welcome Bonus upon the initial deposit, which is 100% up to €100. To qualify for it, you need to deposit at least €20. The wagering requirements are 25 times the deposit and bonus amount, and your bet shall not exceed €5. Afterward, you’ll have 14 days to fulfill the conditions, as this is the bonus validity notice. From our perspective, these are quite acceptable bonus conditions, except the bonus expiration, as most operators allow a 30-day notice, which is way better.

Game Selection

The casino has a considerable collection of over 1000 high-quality games, including many video and Megaways slots, and a nice selection of table and live games such as Blackjack, Roulette, Bacarrat, Poker, Keno, Sic Bo. Slot titles include some of the most popular ones, such as Book of Dead, Gonzo’s Quest, Starburst, Bonanza, Reactoonz, and many others. Like already mentioned, you have the option to filter them by a provider, volatility, or a feature such as Gamble Feature, Free Re-spin, Multipliers, Win Both Ways, and others. Before placing a real money bet, you can check the games for free, as many of them support a demo version.

Klirr Casino’s games portfolio is loaded with products from some of the industry’s major developers, such as Big Time Gaming, ELK Studios, Evolution Gaming, iSoftBet, NetEnt, Play’N Go, Pragmatic Play, Quickspin, and Red Tiger. They also have games supplied by smaller providers, such as Hacksaw, Fantasma, Leander, NoLimit City, Push Gaming, Relax Gaming, Red Rake, Stakelogic, and others.

Deposit and Withdrawals

The incoming and outgoing transactions at Klirr Casino are processed only via Trustly, and they are instant. The minimum amount you can deposit is €20. Once you enter the desired amount in the specified field, you have to choose the country you reside in. Then, the logos of the supported banks are displayed, and you have to pick yours. After that, you will be transferred to your online banking page, where you have to enter your ID and password and confirm the payment. The minimum withdrawal amount is also €20, which is fairly acceptable and more than convenient. We couldn’t find further information about a mandatory deposit turnover or any additional transaction fees.

Layout and Navigation

The layout is very easy to navigate through, with a drop-down menu on the right from where you can access the Promotions, the different Games categories, and the live chat. A small round button next to the search bar gives you the option to filter the slot games by feature, provider, or volatility, which could be very handy. Roll down to the bottom of the page to receive information about the casino’s license, the General Rules, and Bonus Terms.

Mobile Casino

Klirr Casino does not offer a mobile app, but you can easily access the website with a mobile browser and enjoy the games as all desktop versions are compatible with IOS and Android and run pretty smoothly.

Klirr Casino - Mobile Version
The bottom line

After detailed research, we can conclude that Klirr looks like a legitimate casino with very clear conditions, a Welcome Bonus, which is quite unusual for Pay N Play casinos, acceptable minimum deposit and withdrawal limits, high-quality games supplied by leading providers, and most of all, a proper operating license. Still, as the casino is brand new, it will take some time to gain our recognition and recommendation to players.
