Spin King Sister Sites 2026

Happy Tiger

Happy Tiger is very much the original as far as this casino network goes, and will always be the yardstick against which any future Spin King sister sites will be judged. It’s also quite an old casino by this stage. Some of you might recall it being advertised on UK television a few years back, and that exposure has won the casino a large audience. It’s a very strong all-rounder, offering bingo as well as slots and other casino games, and is well known for its “triple your money” welcome promotion. You could even say that Happy Tiger was such a big success for the company that owns it that it’s the whole reason that this was a one-brand casino network for such a long time – they simply didn’t need to add any more brands because they were making so much money from the one they had.

Bingo Burst

When Happytiger Aps finally decided to expand beyond the single brand that had done them so well for so long, Bingo Burst was the new addition that they settled on. If we’re honest, we can’t for the life of us work out what the plan was. In almost every way that matters, Bingo Burst is a clone of Happy Tiger, right down to using the same welcome promotion and even the same colour scheme. Given that Happy Tiger already offers plenty of bespoke bingo rooms, Bingo Burst didn’t bring anything new to the Spin King sister sites family by focusing on bingo. All it offers is more of what most players have already experienced while playing at Happy Tiger, and for that reason alone, we’re not surprised that it hasn’t achieved anything like the level of success of its better-known twin brand.

Spin King Review 2026

We knew Spin King was coming for a very, very long time before it finally launched in May 2025. The casino’s name and URL had been registered with the UK Gambling Commission since mid-2024, around the time of the launch of Bingo Burst. We’re not sure what took Happytiger ApS so long to get Spin King Casino off the brand, but when it launched, we were glad to see that it’s not another Happy Tiger clone. This appears to be something new, but is it also something good? Let’s see.

Spin King Welcome Bonuses

There are two welcome promotions at Spin King Casino. One of them, a simple offer of twenty-five wager-free spins in return for depositing and wagering £10, is designed to help you get to know the casino. The other promotion is a little bigger. It’s a 100% matched deposit worth a maximum of £100, and it comes with a further twenty-five free spins. The maximum you’re able to win from the bonus is x7 the size of your deposit, and you’ll have to conquer x40 wagering requirements before the bonus money turns into real cash. That’s a smidge higher than the x35 industry average.

Other Promotions

In keeping with Spin King’s royal theme, the casino promises “Royal Treats” to all of its loyal players. It keeps the nature of these treats close to its chest, though. There isn’t a Promotions page or a Bonuses page at Spin King, and all the homepage tells us is that players who register with Spin King and then sign up for the casino’s newsletter will have additional promotions and rewards sent to them by email. It’s great that the casino takes a personal approach like this, but it makes it impossible to know whether or not the rewards are actually worth bothering with.

What are the Pros and Cons of Spin King Casino?

Pros: This is a purpose-built slots casino with an emphasis on jackpot slots and quite a few in-house exclusives. If you’re using PayPal or instant banking, your withdrawals should be processed instantly unless the casino requires further verification.

Cons: It’s a smaller casino than its sister sites, offering no bingo, live casino games, or anything else beyond slots. It’s also light when it comes to bonuses, with no guarantees that you’ll get anything at all on the bonus front save for the welcome bonuses, the terms of which aren’t fantastic.

Top Slots and Games

Oddly, despite making quite a lot of noise about having in-house, exclusive slots available, Spin King Casino doesn’t include any of them in its “cherry-picked UK favourites” on its homepage. Instead, the section is stacked full of tried-and-trusted slots and casino games that have proven to be popular with players for years. As an example of that, you’ll find Starburst in the top row. You’ll also find Sweet Bonanza and Gates of Olympus, both of which are considered hallmarks of a high-quality slots selection. Big Bass Splash and all the other Big Bass Bonanza spin-offs and sequels are available here, too.

If you’re looking for something a little less obvious, you might be inclined to give Temple of the Sun a try. In general, anything that’s paying out regularly and/or particularly popular with players at the time of your visit to Spin King, it’ll have a little yellow ‘HOT’ tag on its thumbnail to make it easier to spot. From Piggy Riches Meagways to Jack and the Beanstalk and 777 Strike to Sugar Rush, you should find that Spin King has every popular slots game you might have enjoyed elsewhere. We still think the collection is a little too small, though – if you’re launching a slots-only casino, it really ought to have more than one thousand slots available.

Withdrawal Processing and Support

You can use a debit card to get your money out of Spin King Casino if you really want to, but it’s the least efficient way to do it because you’ll be waiting between one and three business days for your funds to arrive. If you’d like things to move along a little faster than that, you can use PayPal, Apple Pay, or even a good old-fashioned bank transfer, all of which are processed immediately once your request has been approved. That should result in same-day money more often than it doesn’t.

Customer Support and Licensing

Finding casinos that still offer telephone-based support in this day and age is a rarity, so we’re really pleased that Spin King is happy to speak to players directly if they call 0800 102 6145. The telephone line is only staffed between 10am and 8pm, though. If you’re playing outside of these times, you can see the chat service or email the casino at support@spinking.com.

As a Happytiger ApS casino, Spin King is covered by UK Gambling Commission licence 57641. The company is based in Denmark – quite an unusual place for a casino network company serving the UK to be based – but that doesn’t stop it from getting a licence. There are no fines or other regulatory incidents on record for the company, and the same licence also applies to the Spin King sister sites.

Spin King Casino – The Verdict

Having waited for such a long time for Spin King Casino to go live, we were a little worried that it might turn out to be a disappointment of the same kind that Bingo Burst was. We’re happy to confirm that we were worried about nothing. Spin King isn’t a revelation of an online casino, and it doesn’t attempt to reinvent the wheel, but it’s solid, full of great games, and offers players high-quality customer support. If you like jackpot slots and you’re not especially eager to find rare slots or games from smaller studios, it should do you just fine. We still think it could use some more promotions, though, and there’s plenty of room to expand its portfolio, too. Still, it’s off to a strong start, and we think it’s going to be popular.
