The MamzinoBet sister sites in a nutshell
MamzinoBet is a casino and sportsbook from ProgressPlay Limited, which holds a UK Gambling Commission licence. Its sister sites are close to identical in places, so I’ve picked five that differ in ways you might care about: RubyBet, BetDukes, JesterBet, BetNeptune, and Tangobet.

Five MamzinoBet sister sites worth comparing
ProgressPlay runs well over a hundred sites, and many of them are built from the same parts. These five MamzinoBet sister sites all offer casino games and sports betting, but each one changes something: the offer, the look, or both.
RubyBet
- The biggest bonus match here: RubyBet’s welcome bonus is 100% up to £200, the biggest of any casino I’ve profiled here.
- Same deposit, four times the bonus: A £200 deposit earns the full £200, whereas MamzinoBet would only give you £50 for it.
- No spins attached: The deposit bonus doesn’t add any free spins, so you’d lose the 20 that MamzinoBet includes.
- Double the free bet: Bet £10 and you get a £20 free bet, with odds of at least 1.5.
- A familiar face: Apart from the red ruby logo and the offer, its casino homepage matches MamzinoBet’s almost exactly.
- Best for: Casino players who deposit more than £50 at a time.
BetDukes
- A mascot of its own: A silver-haired man in black and yellow fronts the site, and he appears in the picture for each category too.
- Four times the free bet: Bet £10 and you get a £40 free bet, compared with £10 at MamzinoBet.
- A sports guide up front: Its front page has its own write-ups for football, horse racing, greyhounds, darts, snooker, and Formula 1.
- Small but generous bonus: The casino bonus is 200% up to £20, which means £10 is enough to get all of it.
- Bingo in place of live dealers: The top menu comprises Casino, Sports, and Bingo.
- Best for: Sports bettors who’d like a site with more personality.
JesterBet
- The closest match: JesterBet advertises the same 25% up to £50 bonus and free spins on the same terms.
- The one big change: Its sports betting welcome offer is a £40 free bet, for the same £10 minimum deposit that gets you £10 at MamzinoBet.
- A slip in the small print: The line under the banner says the free bet is a “one-time stake of £10”, while the full terms say £40. It’s sloppy, but go by the full terms.
- The extra tab: It lists Bingo after Casino, Sports, and Live Casino, whereas MamzinoBet stops at Live Casino.
- Gold and green logo: The jester’s hat badge is about the only visual change from MamzinoBet.
- Best for: Anyone who was going to join MamzinoBet for its sportsbook.
BetNeptune
- Under the sea: Deep teal backgrounds, a trident logo, and yellow highlights make this easy to tell apart from MamzinoBet at a glance.
- Twice the rate and twice the limit: The welcome bonus is 50% up to £100 plus free spins, so £100 earns £50 rather than £25.
- No gain on sports: Its free bet is £10, the same amount as MamzinoBet’s, and you have to bet £10 to get it.
- The same games: The New row opens with Wonder Train, Le Clubber, and Nugget Ridge, just as it does at MamzinoBet.
- Bingo rooms: Fluffy Favourites Bingo and Rainbow Riches Bingo are among the rooms in its Bingo section.
- Best for: Casino players who want a better bonus and a different look.
Tangobet
- Spins, not a match: The welcome bonus banner advertises 50 free spins on Big Bass Bonanza Megaways instead of a matched deposit bonus.
- A bigger sports offer: Deposit at least £10 and you get a £30 free bet.
- A longer history: Tangobet moved to ProgressPlay from AG Communications, and I’ve covered the implications of that move in more detail on its own review page.
- Plain branding: The red-and-white logo is simple, and most of the site follows the same layout as MamzinoBet.
- Best for: Slots players who’d prefer free spins on a well-known game to a small matched deposit bonus.
The research behind this MamzinoBet review
Here’s where the facts in this MamzinoBet review came from. I explain how I review casinos more generally on my About Us page.
Rob Hill
I compared the casino and sports homepages of MamzinoBet and its sister sites as a new player from the UK would, and read the full terms behind the welcome offers. I confirmed the licence and its regulatory record with the regulator.

Best MamzinoBet sister sites by player type
If you deposit larger amounts
RubyBet keeps matching your first deposit at 100% all the way to £200.
If you mainly bet on sports
BetDukes pairs a £40 free bet with a site built around its sportsbook.
If you already like MamzinoBet
JesterBet gives you the same casino offer on the same layout, with a bigger free bet.
If you’d rather have spins
Tangobet leads with a 50-spin offer on Big Bass Bonanza Megaways.
Spot the difference: three casinos, one homepage
Open the casino homepages of MamzinoBet, JesterBet, and RubyBet side by side, and you’d struggle to tell them apart without checking the logos. The Greek gods and the cowboy are in the same place, in front of the same swirling portal. The New row below them runs in the same order, and the small print appears in the same spot.
So what does change? Mainly the logo, the welcome offer, and the menu, as MamzinoBet is the only one of the three without a Bingo tab. The MamzinoBet logo is plain white lettering with a red Z, and the site has nothing of its own to set it apart in terms of theming. The About Us page says it was founded in 2026, but there’s nothing on the site to tell you why you’d choose this brand over any of the others.
Not every ProgressPlay site is this identical. BetNeptune changes the colours and BetDukes adds its own styled homepage and mascot, although both open into a very similar games lobby. That’s the key thing to remember with the MamzinoBet sister sites group: you’re rarely choosing between different setups. You’re choosing between different bonuses and different colours.
What a £50 deposit gets you across the group
The offers are where these sites part ways, so I’ve used one example. Deposit £50 at MamzinoBet or JesterBet, and you’d get a £12.50 bonus plus free spins. At BetNeptune, you’d get £25 plus free spins. At RubyBet, you’d get £50, with no spins. BetDukes would give you its £20 maximum, and Tangobet’s banner offers 50 free spins rather than a matched deposit bonus.
MamzinoBet’s welcome bonus matches 25% of your deposit up to £50 and comes with 20 spins on Book of Dead, and the £50 maximum requires a £200 deposit. The minimum deposit is £10. The bonus and the spin winnings both have 10x wagering requirements, with 30 days for the first and seven days for the second. You can only keep as much as the bonus amount from the bonus, and £20 from the spins. Skrill and Neteller deposits don’t qualify, and asking to withdraw cancels the bonus.
On sports, the same £10 minimum gets you a £10 free bet at MamzinoBet, which requires odds of at least 1.5 and doesn’t return the stake. The winnings have 1x wagering, up to £200. That’s the joint-smallest free bet on this page, with JesterBet and BetDukes offering £40 and Tangobet offering £30.
The terms that follow you around the network
The offers may differ, but the terms and conditions treat these sites as one business. The MamzinoBet terms define the “Company Network” as the official list of sites regulated by the UK Gambling Commission, and the word “network” in the offer’s small print links straight to ProgressPlay’s list of domains on the UKGC register.
The clearest rule is on sports betting. The full terms say “Any player can receive up to 1 (one) sport welcome bonus on the Progressplay Network.” That makes your first sports bonus worth thinking about, because using it on a £10 free bet at MamzinoBet means you can’t claim £40 at BetDukes or JesterBet afterwards.
The casino rule is less clear. The offer says “Limited to 5 brands within the network”, and the full offer terms don’t explain how that’s counted. I take it to mean you can claim a casino welcome bonus at five of these sites at most, which is more reason to choose them carefully.
Two more clauses in the MamzinoBet terms matter here. Registering multiple accounts within the Company Network to take advantage of a promotion counts as abuse. You also have to confirm that you haven’t previously self-excluded from another account on the Company Network, so if you’ve self-excluded from one ProgressPlay site, opening an account at a sister site isn’t a way around it.
Who runs MamzinoBet?
UKGC Licensed, ProgressPlay Limited (39335), click to verify
ProgressPlay Limited operates MamzinoBet as a white-label site. It’s held UK Gambling Commission licence 39335 for remote casino since 1 November 2014, for betting since 17 December 2018, and for bingo since 23 August 2024. The website gives a Malta address, and the UK register lists an office in Limassol, Cyprus.
The register’s domain list includes 20 active sites, 95 white-label sites including MamzinoBet, and 76 inactive addresses. All five sister sites on this page are in the white-label group, along with others such as Hippozino and Betmaze.
ProgressPlay has one regulatory action on its record. On 9 May 2025, the Gambling Commission imposed a £1,000,000 financial penalty, a formal warning, and a licence condition requiring a third-party audit. It found anti-money laundering failures under Licence Condition 12.1.1 and 12.1.2, and customer interaction failures under Social Responsibility Code Provision 3.4.3. The Commission said ProgressPlay co-operated throughout and took steps to fix the problems.
A very large lobby, and plenty of spin offers
The games lobby at MamzinoBet is typical of the ProgressPlay catalogue, with more than 6,600 titles when I looked. Microgaming classics such as Immortal Romance, Thunderstruck II, and Break da Bank Again are there alongside new arrivals like Monkeys Ahoy, Killer Night, and Forever Split Megaways. The other providers include NextGen Gaming, ELK, Big Time Gaming, Thunderkick, Eyecon, and Just For The Win. You can search by game or provider, and most games have a demo version, which is handy if you’d like to try before you deposit.
The regular casino promotions mostly ask you to deposit £20 for a chance at free spins. Mystery Box is available once a day from Monday to Thursday, the Midweek Wheel of Prizes runs on Wednesdays, and the Weekend Wheel of Spins runs on the last three days of the week. There’s also a Rewards Programme, where missions, levels, and badges earn you points to spend in a Rewards Store. On sports, the regular list includes an Acca Super Boost and a bet builder.
Slow card payouts and a withdrawal fee
You can pay with Visa and Mastercard debit cards, PayPal, Skrill, Payz, Neteller, Apple Pay, Paysafecard, or Instant Bank Payment. Each withdrawal starts with one business day of processing. Skrill, Neteller, and Instant Bank Payment then take one more business day, Payz, Apple Pay, and Paysafecard take three, and debit cards and PayPal take 3 to 7. Mastercard withdrawals aren’t available, which is odd and disappointing.
There’s a processing fee of 1% on each withdrawal, up to £3. It isn’t a fortune, but most UK sites don’t charge one at all, so it feels stingy. Accounts become dormant after 12 months, followed by a £5 monthly fee once you’ve had 30 days’ notice. The terms also say customer money is kept in a separate account but isn’t protected if the company goes bust.
Support opens a help centre with links to live chat, and the About Us page says the team is available 24/7. You can also email customersupport@instantgamesupport.com, but there isn’t a customer support phone number. If you need to complain, write to complaints@instantgamesupport.com no later than six months after the problem. The terms promise an acknowledgement inside 24 hours and a final decision inside eight weeks, and eCogra is the independent dispute service named in the terms if that doesn’t settle it.
What I like, and what I don’t
What I like
- Free spins for a deposit on most days of the week.
- Missions, badges, and a Rewards Store to spend points in.
- A very wide choice of game providers.
- Demo play for trying games before you deposit.
What I don’t
- A 25% welcome bonus, when RubyBet offers 100% on the same terms.
- A £10 free bet, when your one sports welcome offer could be worth £40 elsewhere on the network.
- A 1% fee on every withdrawal.
- Nothing about the casino that gives you a reason to remember it.
My MamzinoBet sister sites verdict: same site, smaller offers
If MamzinoBet were the only site of its kind, I’d call it a decent enough casino and sportsbook. It isn’t, and the comparison doesn’t flatter it. When a sister site can look almost the same, stock the same games, and carry the same licence, the welcome offer is the only thing left to judge it on, and MamzinoBet is at the low end for both casino players and bettors.
The sports betting case against it is the strongest, because the network gives you one welcome offer and JesterBet shows you could get four times as much from an almost identical site. For casino play, it depends how much you deposit: RubyBet makes more sense with a larger first deposit, and BetDukes with a small one. I don’t see any harm in joining MamzinoBet later for its regular spin offers, but I wouldn’t start my tour of ProgressPlay casinos here.
