Mr Slot sister sites in a nutshell
Mr Slot is operated by ProgressPlay Limited of Malta on Gambling Commission account 39335, one of the largest white-label estates in British gambling, whose register today lists 186 domains. Its sister sites therefore number in the dozens, but the family within the family is the fun part: ProgressPlay’s shelf holds six Mr-branded casinos, Mr Slot, Mr Jack Vegas, Mr Mobi, Mr Rex, Mr SuperPlay and Mr Vegas Casino.

The Mr Slot sister sites
ProgressPlay’s Gambling Commission register entry, counted today, runs to 186 domains: 20 active brands the operator runs directly, 99 white labels with mrslot.com among them, and 67 retired addresses. If you’re looking for its sister sites, I recommend taking a walk down the Mister row. Six Mr-branded casinos trade on the licence, and the five that aren’t Mr Slot make a neat, strange family portrait, three of them near-identical veterans in the platform’s old clothes, one dressed for sport, and one wearing a name that belongs to somebody more famous.
Mr Jack Vegas
- The Vegas-flavoured Mister: Casino glitz on the platform’s classic shell, where Mr Slot splits its attention between slots and bingo.
- Same wagering rules: The own-money-first, 10x machinery printed on its banners matches Mr Slot’s line for line.
- Older wardrobe: One of three Misters still wearing the platform’s older template, simplified navigation and all.
- Identical paperwork: The same licence, fee clause and not-protected funds tier as Mr Slot.
- Who it suits: Players who want Mr Slot’s machinery with showgirl wallpaper.
Mr Mobi
- The mobile-era Mister: Named for the phone-first years and still pitching mobile slots as the point, a heritage Mr Slot doesn’t call on.
- Twin under the paint: The same veteran shell, category menu and banner terms as Mr Jack Vegas, and the same engine as Mr Slot.
- Casino-only counter: No bingo wing, which is Mr Slot’s one clear product edge over it.
- One complaints route: eCOGRA at the end of the ladder for both brands.
- Who it suits: Players nostalgic for the era the name comes from.
Mr Rex
- The modern one: A current-generation build with casino, live rooms, bingo and a sportsbook, the widest menu of any Mister, including Mr Slot.
- A different welcome offer: Fronts 50% up to £100 on the first deposit, trading Mr Slot’s bigger percentage for a higher ceiling.
- Dinosaur branding: The one Mister with an actual character on the crest.
- Same spine: ProgressPlay’s terms, fees and funds tier behind the modern front, exactly as behind Mr Slot.
- Who it suits: Anyone wanting sport and a mascot beside the slots Mr Slot serves plain.
Mr SuperPlay
- The third of the veteran trio: Completes the matching set with Mr Jack Vegas and Mr Mobi, on the same classic shell Mr Slot has outgrown.
- Superhero-tinged name, standard setup: The branding promises more than the template delivers.
- Banner terms in unison: The 10x, own-money-first line again, the platform’s chorus across all six Misters.
- Same protections: GAMSTOP, segregated-but-unprotected funds and eCOGRA, as at Mr Slot.
- Who it suits: Completists; between the veteran trio, the differences are wallpaper-deep.
Mr Vegas Casino
- Not the famous one: This is a ProgressPlay brand at mrvegascasino.com, a different casino entirely from Mr Vegas, the well-known Videoslots brand; two brands and two unrelated operators.
- Package pitch: Advertises a welcome package up to £150 in 25% instalments, a slower drip than Mr Slot’s single 100% match.
- Casino, live and bingo: Matches Mr Slot’s bingo wing and adds live rooms to it.
- Same estate rules: ProgressPlay’s fee, funds and bonus clauses apply here exactly as at Mr Slot.
- Who it suits: Nobody looking for the more famous casino, ideally: check the address bar before you sign up.
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.

Personally tested. Account opened, deposit and withdrawal made. The lobby was read in full (homepage, the promotions page with the welcome offer’s printed terms, and the full terms and conditions reached through the site’s own footer link), the UKGC register was re-read the same day, and all five profiled sister sites were loaded fresh.

A gentleman’s name on a platform’s standard shelf
Mr Slot presents itself simply: a title-case gentleman’s name over a two-wing shop, casino on one side, bingo on the other, which already makes it more versatile than most of the estate it belongs to. The lobby’s promotional row shows where its energy goes: a welcome on the slot Sweet Burst, a shared 200 Cash Spins event, and 100 free spins on 3 Hero Piggies for depositors, each banner wearing the platform’s dense small print like a uniform. It’s a tidy, functional storefront rather than a themed world; the personality budget on this licence clearly went to the dinosaur next door. The housekeeping could use a sweep, though: the main banner was still advertising its weekly event as running “every week this June” while its own small print counted the weeks of July.
One commendable detail hides in the terms rather than on the homepage: stake limits that step by age, a £5 maximum per spin for players 25 and over, tightening to £2 for younger players. That’s a stricter default than most licensed rivals use, and it’s worth knowing if you’re one of my younger visitors.
Ownership, licensing and the UK position
The footer identifies the machine: MrSlot.com is operated by ProgressPlay Limited, a Maltese company (C58305) of St Julians, licensed by the Malta Gaming Authority since 2013 and by the Gambling Commission under account 39335. On the register, mrslot.com sits among the licence’s 99 white labels, part of an estate of 186 domains that makes ProgressPlay one of the biggest single licensees a British player can encounter, a scale this site documents in full on its dedicated ProgressPlay operator page.
Two facts about that licence belong beside every brand on it. First, the Commission fined ProgressPlay £1 million in May 2025 for anti-money-laundering and customer interaction failures, with the licence retained; recent history. Second, the funds arrangement sits at the bottom rung the Commission recognises: Mr Slot’s own terms state customer money is held in segregated accounts but is “not protected in the event of insolvency”, the not-protected level. Segregation is bookkeeping, not a guarantee, and on this licence there’s no guarantee behind it. The rest of the machinery is standard: GAMSTOP applies, eCOGRA is named as the free dispute adjudicator, and the affordability and verification checks run as UK rules require.

The welcome, and the four-pound fine print
On the banner, the welcome reads generously enough: 100% up to £25 plus 40 free spins on Sweet Burst. The printed terms then take it apart piece by piece. Wagering runs from your real balance first, so your own money is spent before a penny of bonus is touched. The bonus carries 10x wagering within 30 days, calculated on bonus bets only, on selected games with varying contribution. The spins’ winnings carry their own 10x within 7 days. And then the clause that defines the offer: winnings can turn into no more than one times the bonus amount, or, from the free spins, £4. Forty spins, advertised on the front of the shop, that cannot under any outcome put more than four pounds in your pocket. It’s all legal, it’s all printed, and it’s the least a bonus has been worth any page I’ve written this month.
The conditions keep going: the welcome is valid at only five brands across the network, so a player who’s used it at sister sites may already be excluded; deposits via Skrill or Neteller don’t qualify; and a withdrawal request voids any active or pending bonus, a clause that punishes cashing out while anything is in play. The rest of the calendar runs tournament and weekday promotions under the same grammar, 200 Cash Spins shared events and a 100-spin offer on 3 Hero Piggies among them. The arithmetic advice writes itself: at Mr Slot, read every number twice, and treat the second reading as the truth.
Deposits, withdrawals and the cashier
Withdrawals at Mr Slot are subject to a processing fee of 1%, capped at £3 per withdrawal, written into the terms and conditions. Charging players to receive their own money is nearly extinct among UK licensees, and this platform keeps it alive; small in absolute terms, poor in principle, and worth knowing before you deposit. Balances below the minimum withdrawal can at least be recovered in full by contacting support, and a dormant account fee of £5 a month waits for anyone who walks away without emptying the till.
Deposits run through the cashier’s card and e-wallet options, with the terms flagging that Skrill and Neteller deposits sit outside bonus eligibility, and the standard verification precedes a first payout. No payout-speed promise appears in the terms, and given the fee clause, the withdrawals page deserves the closest read of anything behind the login.
Support and complaints
Support runs through the platform’s shared channels: live chat and a contact route from within the site, with no phone line offered. It’s the same service desk that answers for dozens of ProgressPlay storefronts, which keeps it staffed if not personal.
Complaints climb the internal ladder first, and the terms name eCOGRA as the alternative dispute resolution entity, free of charge, once the operator’s process is exhausted. With a fee clause and cash-out ceilings in the terms, knowing the referee’s name and price matters more here than at gentler casinos..
What I like, and what I don’t
What I like
- A bingo wing beside the casino, which most of this network’s storefronts don’t offer.
- Age-stepped stake limits, £2 a spin for under-25s, stricter than the market standard.
- Everything is printed: the caps, the fee, the funds tier; nothing here hides.
- eCOGRA named, free, at the end of the complaints ladder.
What I don’t
- Forty advertised welcome spins whose winnings convert to £4 at the absolute most.
- A 1% fee, capped at £3, on every withdrawal, plus a £5 monthly charge on dormant balances.
- Customer funds at the not-protected tier, on an operator fined £1 million in May 2025.
- A withdrawal request voids pending bonuses, and Skrill and Neteller deposits are shut out of offers.
My Mr Slot verdict: read it twice, then decide
Mr Slot is honest in the way a parking ticket is honest: every unfriendly number is printed exactly where the rules require. The £4 ceiling on its welcome spins, the 1% withdrawal fee, the not-protected funds tier and the bonus-voiding clause are all there to be read, and I’ve read and reported them so you don’t sign up on the banner alone. Nothing about the casino is hidden or lawless, and the bingo wing and the age-stepped stake limits show flashes of a shop thinking about its customers. But a welcome whose spins top out at four pounds, on a licence that charges you to withdraw and was fined seven figures last year, is a hard sell against the UK market’s current standard. Independent player feedback on this brand is too thin on the ground to tilt the scales either way.
Within the family, Mr Rex offers the widest menu, and the only mascot with visible effort behind it, and the veteran trio are Mr Slot with different wallpaper; know that the estate’s terms travel with you to all of them. Check the address bar carefully before visiting Mr Vegas Casino, which is this network’s brand and not the better-known Mr Vegas. And if what drew you here was the promise of free spins that pay, the signpost points off this licence entirely, toward the operators whose spin winnings arrive as cash with no ceiling attached.
