Coolzino Sister Sites 2024


Coolzino doesn’t list its operator anywhere on its website, which isn’t unheard of for international casinos. However, the design template is unique to Uno Digital Media B.V., so we’ve identified Coolzino as part of their network. This group of international casinos is growing rapidly and is very popular, with the Coolzino sister sites including some of the biggest names in the category. However, UK players should be aware that these casinos aren’t licensed by the UK Gambling Commission, making it illegal to play at them in the UK.

Kinghills Casino

Kinghills Casino

When Kinghills Casino popped up and joined the rest of the Coolzino sister sites in 2024, we thought it was a case of the operator getting lazy. It follows the same formula as the other casinos on the network, and we doubted Uno Digital Media could pull off another success without offering players something different. We don’t say this often, but we were wrong. Like the big-name casinos that came before it, Kinghills Casino quickly drew in thousands of players. You’d think the market would be overwhelmed with so many similar casinos, but players know what they’re looking for, and they clearly appreciate the Uno Digital Media B.V. approach. Despite the name “Kinghills” sounding more like a car park than an online casino, it hasn’t made a difference to its appeal. The excellent games and promotions are what attract players, and once they’re in, they tend to stick around.

Winaura Casino logo

Like every casino that joins the ranks of the Coolzino sister sites after the success of Nine Casino and NineWin Casino, Winaura faces an uphill battle to achieve the same kind of success. Its chances aren’t helped much by the fact that it’s gotten itself in a bit of a muddle with some of the core content on its website. There are links on the homepage that are supposed to take players to the standard Uno Digital Media B.V. sportsbook, but Winaura doesn’t offer the sportsbook. That’s what happens when you get a little bit too eager with the copy-and-paste function when you’re putting casinos together from a base template. Aside from that, though, Winaura seems to be made of the same strong foundations as the other casinos on the network, and shines a spotlight on its ever-growing collection of popular crash games.

R2PBET logo

In the parlance of international politics, R2P stands for Responsibility to Protect, which is the obligation of all nations to cooperate and prevent global atrocities if at all possible. That would make an odd theme for an online casino, so we think the “R2P” in the unusual name of this member of the Coolzino sister sites family is more likely to mean “Return To Player,” which is the rate at which a casino game is likely to offer you a return on your wagers. It’s one of the blander casinos on the platform in terms of theme and appearance, and it also offers one of the network’s smaller offers. That’s actually something that R2PBET has in common with Coolzino, which is a little bit of a spoiler for our full review of the casino further down this page. In fact, the two sites are almost identical.

On paper, NineWin Casino shouldn’t have worked. It was one of the first casinos that Uno Digital Media B.V. launched after the runaway success of Nine Casino, so all eyes were on the operator to see what it would come up with. The answer was a casino site that resembled Nine Casino in every way imaginable, including the name of the casino. Instead of being the end of the operator’s success story, though, NineWin Casino proved to be just as a big a hit as the casino that “inspired it,” instantly becoming one of the most popular Coolzino sister sites and remaining in that category today. The long and short of it is that if you’ve played at Nine Casino and enjoyed it, you’re nailed on to also enjoy your time at NineWin Casino. You should probably check both of those casinos out ahead of the other Coolzino sister sites.

Memo Casino

Memo Casino logo

Memo Casino is, like all the rest, a close cousin of Nine Casino, designed using the same template and offering the same features. We could end this mini-review there, but there are a couple of things to be said in Memo Casino’s favour. One of them is that the casino comes with hints of a disco theme, which is more than you’ll find at any of the other Coolzino sister sites in terms of theming, and we include Coolzino itself in that. The other is that Memo Casino offers you a slimmed-down version of the operator’s standard offering. The casino dispenses with both real and virtual sports betting, allowing it time and space to focus more heavily on its massive portfolio of thousands of slots. If you couldn’t give two figs about sports and just want to spin the reels, Memo Casino would love to see you.

Coolzino Review 2024

The name of Coolzino isn’t difficult to understand. It’s a casino, and it’s cool. The idea of it being cool is supposedly enforced by the use of emojis in its logo, although we’re not sure that emojis have been cool since the turn of the decade. Like nearly all the casinos on this network, it’s largely presented without a theme and comes with the same core ingredients and content as the likes of Nine Casino (to which all sites on this platform are compared), but let’s see if it can find a way to stand out from the ever-growing crowd.

Coolzino sister sites homepage

Coolzino Welcome Promotions

Most casinos on this platform offer a welcome bonus that includes matched deposits up to £450 and 250 bonus spins. Players usually need to make three deposits to get the full bonus amount. However, Coolzino does things a bit differently. While the number of free spins remains the same, the total amount of available bonus cash is reduced to £300. Unfortunately, we can’t give you the exact breakdown of how the bonus is divided among the deposits, as the details have been left off the promotions page, likely by mistake. This is quite an error for the designer to make. We believe the wagering requirement is x35, but we can’t confirm it because of this omission.

Other Promotions

Coolzino has a decent selection of bonuses, with the cashback deal being a highlight from the collection. If you end a session with losses, they’ll refund twenty-five per cent of those losses the next week. It appears there’s no limit to this offer, but the exact cashback percentage depends on your VIP level. We’ll get into the VIP scheme in a second. Another bonus feature is the daily spin-the-wheel offer, where players can win a small prize every day.

One thing that sets Coolzino and the other Uno Digital Media sites apart from the norm is that they have both a loyalty scheme and a VIP Club, which is unusual as most casinos class such things as one and the same. The loyalty scheme includes four levels, and you advance by earning points from playing games, with extra points available through the completion of special missions assigned by the casino. Each level achieved gives you a cash reward and an extra one per cent in weekly cashback. The VIP Club, however, is a secretive organisation. The casino doesn’t give much detail about how to join or what benefits you get once you’re in. It seems likely that membership is by invitation only.

What are the Pros and Cons of Coolzino?

Pros: All of the casinos on this network tend to have the same strengths, and Coolzino is no different. There are thousands of slots to choose from – far more than you’ll get at the majority of international casinos outside the GamStop zone. New games arrive all the time, and crash games are plentiful if that’s what you’re into. The Ts and Cs of the casino’s bonuses are broadly fair.

Cons: There are a few problems here, not least the fact that there’s a link to sports betting bonuses on the Promotions page. Coolzino doesn’t have a sportsbook, so that’s a careless bit of code left over after a copy/paste from one of the operator’s other sites. The welcome bonus is smaller, and unlike its best sister sites, Coolzino appears to be unlicensed.

Top Games at Coolzino

As we just said, Coolzino doesn’t include sports betting, which is a bit odd considering all the other top sites on the network do offer it. However, shifting our focus to what the site does offer, you’ll find a balanced variety of iGaming categories. Slots, live games with real dealers, and a selection of crash and instant-win speciality games are all prominently featured, with none seemingly given more spotlight than the others. This can be seen in the ‘Popular Games’ section smack in the middle of the homepage.

This section’s lineup changes periodically, but the favourites always seem to stick around. For instance, Big Bass Bonanza Megaways by Reel Kingdom is a staple, part of the vast Big Bass Bonanza collection, which includes what feels like an infinite number of sequels like Big Bass Bonanza: Keeping It Reel, which was also featured during our review. Another interesting choice in the top picks is Congo Cash from Pragmatic Play, which offers a jungle adventure theme. Not to be overlooked are Bubbles and Chicken Road by Inout, two instant-win novelty games, marking a growing interest in this type of entertainment. They’re a refreshing break from the usual slot offerings and add a unique twist to the casino’s roster.

Withdrawal Processing & Support

It’s a bit of a pain that Coolzino doesn’t have a dedicated banking info page, but we’ve pieced together enough details to paint a clear picture for you. The standard option for pulling out your winnings is via your debit card. If you’re into e-wallets, you’ve got choices like Skrill, Neteller, MiFinity, and Jeton, though PayPal isn’t on the list, which might be bad news for some. AstroPay is also on the table, but it seems the casino has a bigger soft spot for cryptocurrencies, accepting most of the major ones through their respective wallets, with Bitcoin being a particular favourite. However, as heads-up, none of these methods are particularly quick. Withdrawals can drag on for up to five working days. Considering that crypto and e-wallet transactions are typically near-instant, this delay can feel unnecessarily long.

Customer Services & Licensing

If you need help at Coolzino, the quickest option is the live chat feature. This tool is available 24/7 and should put you in touch with a casino support agent in no time. If live chat isn’t your thing or if it’s too busy, you can always drop an email to [email protected] and wait for a reply. On a different note, while the top Coolzino sister sites are all registered with Curacao eGaming, Coolzino itself doesn’t seem to hold any such licence. Typically, one licence would cover all the casinos in an operator’s network, but not here, it seems. It’s unclear why this is the case; it might just be another oversight by the web design team.

Coolzino – The Verdict

The casino network offers a variety of options, so if you’ve come across Uno Digital Media B.V. because you enjoy what the operator’s done with Nine Casino or NineWin, the good news is that there are several other promising choices available. However, Coolzino might not make the cut right now. The casino could potentially get better with time, and we’re hopeful about that, but at the moment, it’s facing quite a few perplexing problems. For instance, why does the welcome offer fall short compared to those of its sister sites? Why are crucial bonus details missing on the site? Why are there links that lead nowhere? Until Coolzino resolves these issues or provides some clarity, you might be better off with one of the better-established casinos we mentioned at the top of the page.
