The Rainbet Splash sister sites
ProgressPlay’s licence is one of the largest in British gambling: close to 190 domains, of which 101 are white labels like this one, 20 are the operator’s own active brands, and 67 have been retired. Every storefront runs the same platform and the same small print, so the differences that matter are the numbers on the front door, and those vary enormously. One habit shows up across the estate: the bonus is capped at one times its value, free-spin winnings convert at £20 whatever the headline promises, and any offer is limited to five brands network-wide, so touring the family doesn’t multiply what you can take home.
The Online Casino
- Four times the match: Its opening offer is 100% up to £50 with 20 free spins on Book of Dead, where Rainbet Splash matches a quarter of your deposit and adds no spins.
- A sports offer as well: Bet £10, get £10 in free bets, run separately from the casino side as UK rules require.
- The plainest name on the licence: No theme at all, against Rainbet Splash’s weather-and-water styling.
- Same protections either way: Licence 39335, the same funds rating and the same free adjudicator.
- Who it suits: Anyone who likes this platform and would rather start with the biggest match on it.
Bluefox Casino
- The operator’s biggest bonus: A package advertised up to £1,000 with 100 free spins, twenty times the ceiling Rainbet Splash puts on its own offer.
- Read the ceiling, not the banner: The same one-times-bonus cash-out rule sits underneath it, which is exactly why the two headline figures aren’t comparable.
- Betting included: Sports sits in its menu as it does at Rainbet Splash.
- A brand with a face: The fox mascot gives it an identity Rainbet Splash’s name doesn’t quite settle on.
- Who it suits: Players drawn by big numbers, provided they check what converts.
HighStakes
- The same offer, with spins attached: 25% up to £50 like Rainbet Splash, but 25 free spins come with it.
- The same history, too: Its about page opens “Founded in 2012, HighStakes was established to provide quality entertainment”, the claim Rainbet Splash makes with its own name in place.
- Identical shopfront: The casino, sports, live and bingo tabs sit in the same order on both.
- A name promising more than the terms allow: Stakes are capped at £5 a spin by law, whatever the branding suggests.
- Who it suits: Anyone weighing Rainbet Splash’s offer, since this is the same deal with spins added.
Vampire Bingo
- Bingo first, and committed to it: Bingo rooms and live bingo lead the menu, where Rainbet Splash keeps bingo as its fourth tab.
- £30 for a tenner: Deposit £10 and receive a £30 games bonus, triple your money against Rainbet Splash’s quarter.
- A theme that commits: Gothic styling and “let’s take a bite” copy, a stronger identity than most of the Rainbet sister sites network manages.
- Slots underneath: The same jackpot and slot catalogue Rainbet Splash draws on.
- Who it suits: Players who came for the bingo tab and want a site built around it.
SupaBet
- Sports leads here: Deposit £10 for a £20 free bet at minimum odds of 1.5, where Rainbet Splash puts its money behind casino play.
- The estate’s tallest ceiling: Its free bet converts up to £200, ten times what Rainbet Splash’s spin offers allow.
- Stake not returned: Winnings only, the standard free-bet arrangement, and worth knowing before comparing headline figures.
- Same four wings: Casino, sports, live and bingo, in the same layout as Rainbet Splash.
- Who it suits: Bettors who’d use the sportsbook first and treat the casino as the sideline.
How this review was made
Every claim here comes from a source I can point you at, so you can judge the page on its evidence. My full approach is on the About Us page.
Rob Hill
Personally tested. Account opened, deposit and withdrawal made. The site was read in full, including the promotions and their printed terms, the full terms and conditions, the deposits, withdrawals and about pages and the games catalogue. The register entry was read with its domain list confirmed row by row and its regulatory actions record read in full, and five Rainbet sister sites were checked anew.

A new arrival with a borrowed past
The catalogue is the strongest thing here, and it’s substantial: 6,320 games, of which 4,418 are slots and 1,116 are live tables, alongside jackpots, a Vegas section and casual titles, with sports and bingo in their own tabs. The names are the ones British players already know: Starburst, Book of Dead, Rainbow Riches, Gonzo’s Quest Megaways, and most carry a demo mode so you can look before you stake. As a place to play, it wants for nothing.
As a brand, it’s slimmer than it looks. The about page announces that “Founded in 2012, RainBetSplash was established to provide quality entertainment to people who enjoy gambling”, which would make it one of the older names in British online gambling. It isn’t. That fact belongs to the operator, whose Malta-based parent company was registered in 2012, and it appears word for word on sister site HighStakes with its own name dropped in. What you’re reading is the network’s standard paragraph wearing this brand’s badge, and it’s a fair warning about how much of the identity here is the storefront’s own.
Ownership, licensing and the UK position
The footer of the Rainbet Splash website names the operator clearly: ProgressPlay Limited of St Julians, Malta, company C58305, licensed by the Malta Gaming Authority since April 2013 and by the Gambling Commission under account 39335. It’s one of the biggest white-label networks serving Britain, and Rainbet Splash is one of 101 such storefronts on the licence, alongside 20 brands the operator runs in its own name and 67 addresses now retired. GAMSTOP applies, eCOGRA handles disputes free of charge once the internal process is exhausted, and the terms set the contract under Maltese law and the Maltese courts.
Two disclosures deserve equal billing. Customer funds sit at the Commission’s lowest tier, described in the terms as segregated from company accounts but “not protected in the event of insolvency”, meaning a failure of the business could take your balance with it. And on 9 May 2025 the Commission sanctioned ProgressPlay with a £1,000,000 penalty, a warning, and a condition requiring a third-party audit within six months, after finding breaches of anti-money-laundering licence conditions and of the customer interaction code that governs how operators spot players in trouble. The same record notes that the operator co-operated throughout and took corrective steps, and the licence was retained. Both halves are the picture: a serious sanction, and a regulator satisfied enough to let it keep trading under supervision.

The offers, and the ceiling they all meet
The opening offer is a 25% match up to £50, which is small by any standard and indeed the smallest I found across the ProgressPlay platform. Its terms are the network’s: wagering runs at 10x the bonus within 30 days, your own cash is staked before bonus funds, and the cash-out is capped at one times the bonus, so £50 of bonus can turn into £50 and no more. Skrill and Neteller deposits are excluded, requesting a withdrawal cancels any active bonus, and the offer is limited to five brands across the whole network.
The ongoing promotions are where the arithmetic gets interesting. A Weekend Wheel of Spins awards between 5 and 500 free spins on a £20 deposit; the Immortal Warlords offer runs to 75 spins; a monthly promotion advertises up to 315 free spins and £750. Every one of them converts at a maximum of £20. Win 500 spins on the wheel and £20 is still the most that can reach your balance from them, which makes the spin counts a measure of playing time rather than prize money. That gap is the thing to understand here: the big number tells you how long you’ll be spinning, and the small one tells you what you can leave with.
Deposits, withdrawals and a fee worth knowing
Deposits run on Visa and Mastercard debit, including virtual and prepaid cards, and PayPal, with credit cards refused as UK rules require. Withdrawals go back the same way, quoted at one business day to process and three to seven for the money to arrive, and they show on your statement as Babaloo Limited or ProgressPlay Ltd rather than the casino’s name, which is worth knowing before you query an unfamiliar line on a bank statement.
Two clauses stand out, one in each direction. Withdrawals carry a processing fee of 1% capped at £3, small but unusual on a UK-licensed site where free payouts are the norm. Against that, the terms are explicit that your real money balance, deposits and winnings from them can be withdrawn at any time without restriction, and the site applies the legal stake caps of £5 a spin for players 25 and over and £2 for those aged 18 to 24.
Support and complaints
Support runs through live chat and email, with the address given in the terms as customersupport@instantgamesupport.com, a network mailbox rather than a brand one. No customer support phone number is offered.
Complaints follow the internal process first, and if that fails, the terms name eCOGRA as the alternative dispute resolution entity, free of charge, reachable through its own site. That’s the proper UK arrangement, and it’s stated as such. The thing worth noting is jurisdictional: the same terms place the agreement under Maltese law and the exclusive jurisdiction of the Maltese courts, so the free adjudicator is your practical route rather than a British courtroom.
What I like, and what I don’t
What I like
- A 6,320-game catalogue with live tables, sports and bingo behind one login.
- Every cap and exclusion printed under the offer it applies to, not buried.
- Your own deposits and their winnings withdrawable at any time, stated in the terms.
- eCOGRA named free, GAMSTOP in place, and the legal stake caps applied by age.
What I don’t
- A £20 cash-out ceiling under promotions advertising up to 500 free spins.
- The smallest welcome offer on the ProgressPlay network, at 25% to £50.
- “Not protected” customer funds, the Commission’s lowest rating.
- A £1,000,000 penalty on the operator’s record from May 2025.
- An about page claiming a 2012 founding that belongs to the operator, not the brand.
My Rainbet Splash verdict: the games are the draw, not the deal
Rainbet Splash is a competent shopfront on a serious platform, and the case for it is the catalogue: six thousand games, live tables, a sportsbook and bingo, all reached with one account and all under a UK licence with GAMSTOP and a free adjudicator behind it. The case against it is the numbers. A quarter-match to £50 is the smallest opening offer among its own sister sites, the promotions that sound generous funnel into a £20 cash-out cap, and the brand’s own history turns out to be a paragraph the network keeps on file. Too new to have a player record of its own, it has to be judged on its documents, and those describe a casino offering plenty to play with and very little to take away.
If the platform suits you, the family gives you better ways in: The Online Casino matches four times as much of your first deposit, Vampire Bingo turns £10 into a £30 games bonus, and SupaBet’s free bet converts at ten times Rainbet Splash’s ceiling. All of them carry the same funds rating and the same operator record, so choosing between them is a question of the offer rather than the protection. Weigh the £1,000,000 sanction and the “not protected” tier before you deposit anywhere on this licence, then pick the storefront that gives you most for your money. On the current numbers, that isn’t this one.
Rainbet Splash sister sites FAQ: your questions answered
What are Rainbet Splash’s sister sites?
Every brand on ProgressPlay Limited’s Gambling Commission account 39335, which is one of the largest licences in UK gambling: 101 white-label storefronts like this one, 20 brands the operator runs in its own name and 67 retired addresses. They include The Online Casino, HighStakes, Bluefox Casino, Vampire Bingo, SupaBet, Mr Slot, Casino Kings and Jeffbet.
Who owns Rainbet Splash?
ProgressPlay Limited, a Malta company (C58305) based in St Julians and licensed both by the Malta Gaming Authority under MGA/B2C/231/2012 and by the UK Gambling Commission under account 39335. Rainbet Splash is one of its white-label brands rather than a separate company.
What is the Rainbet Splash welcome offer?
A 25% match on your first deposit up to £50. Wagering is 10x the bonus within 30 days, your own cash is staked first, the cash-out is capped at one times the bonus amount, Skrill and Neteller deposits don’t qualify, and requesting a withdrawal cancels any bonus still in play.
Why do the free spin offers mention £20?
Because £20 is the most that can be converted from free-spin winnings, whatever the headline says. The weekend wheel can award up to 500 spins and the monthly promotion advertises up to 315, but the printed terms cap what reaches your withdrawable balance from them at £20 each time.
Is Rainbet Splash safe and legal in the UK?
It’s fully UK-licensed, with GAMSTOP and eCOGRA named as the free dispute service. Consider two things first: customer funds are rated “not protected”, so they may not be returned if the business failed, and the operator was fined £1,000,000 in May 2025 over anti-money-laundering and customer-interaction failings, with a warning and an audit condition attached and the licence retained.
