Monster Casino sister sites: 9 other ProgressPlay brands

That headline costs a lot to reach. You'd pay in £4,040 across 5 deposits for the full £1,000, then place £10,000 of bonus bets at 10x. The terms cap the cash-out from a match bonus at £50 after its 10x, and from a spin offer at £20.

Across 3 match bonuses and 2 spin offers, the package can't convert more than £190 to cash, whatever you win. Here's what else decides whether you get it:

• Each deposit must be £20 or more, through the casino cashier
• Skrill and Neteller deposits don't count
• Asking for a withdrawal cancels any active or pending bonus
• The ProgressPlay terms stop you at 5 casino welcome bonuses, whichever of its brands you sign up to

On 29 September 2026, none of these offers was a no-deposit bonus. Every casino welcome above carries 10x, the most the Commission has allowed since 19 January 2026. Take Monster's second deposit: £800 brings the full £200 bonus, and 10x means £2,000 of bets within 30 days, for £50 at most.

Monster's home page tells you a different story from its terms. Its banner says "Up To £1000 + 100 Free Spins on Starburst". The FAQ calls it a "100% welcome bonus package" needing at least £50. It isn't: the promotion page's terms, with 25% matches and a £20 minimum, set the actual offer.

If you want a plain match, Mogobet and Betmaze each give 100% up to £50 from £10, at 10x on the bonus. That £10 is half the £20 minimum Monster sets per deposit.

If spin winnings matter most, JeffBet's 50 welcome spins carry the highest cap here, £500 against Monster's £20. CasinoKings tops the spin count from one deposit: 100 spins for £20. Casimpo needs 3 deposits to reach its 125.

Why is monstercasino.co.uk missing from the register?

Search the register for monstercasino.com and ProgressPlay Limited comes up, account 39335, domain marked White Label. Try monstercasino.co.uk instead and nothing comes back. It isn't in the account's 192-row table either.

Yet on 29 September 2026, monstercasino.com went straight to monstercasino.co.uk, and your account and cashier sit on games.monstercasino.com. The terms still name ProgressPlay as operator under account 39335, so that's the licence your play falls under. The UKGC licence guide explains each part of a register entry.

In the Commission's words, a White Label domain is one the licensee runs in partnership with another organisation, and the licensee carries the compliance duty. Malta's regulator lists monstercasino.com among ProgressPlay's 117 website URLs too.

Which company runs Monster Casino?

Monster's own site says it was founded in 2021. Its Android app is published by Mediacle Limited, a London company that also publishes the Bluefox Casino and Betmaze apps.

Monster and Bluefox run near-identical 5-deposit welcome packages.

The 9 share Monster's 248-line general terms word for word, brand names aside, all ending "Version 1.2.17 - 21.05.2026". And 9 of those 10 brands run the same 6 opt-in promotions. The Mr Slot sister sites page covers the wider ProgressPlay estate.

Is Slot Monster a sister site of Monster Casino?

No. Here's where each name you might have searched for actually stands:

• Slot Monster sister sites: no casino business by that name or domain is on the Gambling Commission register, so it has no Great Britain licence
• Casino 2020 sister sites: the same, with no register entry for "casino 2020", "casino2020", casino2020.com or casino2020.co.uk
• Dazzle Casino: dazzlecasino.com is still listed on the same account, but as Inactive, which the Commission defines as not in use
• JeffBet: a live sister through jeffbet.net, while jeffbet.com is Inactive on the register even though it still loads

A site with no Gambling Commission licence isn't required by the Commission to offer dispute resolution if something goes wrong. For casinos run by groups other than ProgressPlay, see the full list of sister sites.

How long do Monster Casino withdrawals take?

Monster Casino withdrawal times run in 2 stages, 1 business day of processing and then the method's own transfer time. Added together, you're looking at:

Method	Total, in business days
Skrill, Neteller or Instant Bank Payment	2
Payz, Apple Pay or PaySafeCard	4
Debit card or PayPal	4 to 8

ProgressPlay takes 1% of every withdrawal, never more than £3. A £100 withdrawal costs £1, and £300 or more costs the full £3. Once you've asked, you can't cancel the withdrawal itself. Your statement will show "ProgressPlay Limited", "Babaloo Limited" or "Babaloo CASHOO.EU". Babaloo Limited is the Gibraltar payment processor.

Monster's FAQ words it differently: processing "within 3 business days", and a £50 minimum by wire transfer. It's the withdrawals table, not the FAQ, that you'll want to rely on.

Paying in, you'll want to skip PayviaPhone. It takes a 15% fee and can't receive a withdrawal. The home FAQ still lists "Visa debit/credit cards", although credit cards have been banned for gambling in Great Britain since 14 April 2020.

What other checks and fees apply?

These 3 rules cost players the most, so check them before your first deposit:

• You're verified before you can deposit or play, with photo ID and proof of address from the last 3 months
• Leave your account unused for 12 months and, after a 30-day reminder, you're charged £5 a month until the balance hits zero
• Your money's held in a separate account, but the terms rate it "not protected" if ProgressPlay becomes insolvent

That dormant fee adds up to £60 over a year. Because the general terms are identical, the dormant fee and the "not protected" rating apply at the 9 sisters above too. You may also be asked where your money comes from, at any point.

What does Trustpilot say about Monster Casino and its sisters?

Site	TrustScore	Reviews (last 12 months)
Monster Casino (.co.uk)	1.6	204 (24)
JeffBet	1.2	267 (42)
CasinoKings	1.8	127 (66)
Mogobet	1.5	51 (23)
Fruity King	1.6	39 (12)
Jazzy Spins	2.3	28 (6)

On 29 September 2026, each profile carried Trustpilot's note that its reviews may not be representative. Small samples swing hard. Monstercasino.com shows 2.9 from just 2 reviews, Bluefox has 2 reviews, Betarno 4 and Casimpo 1.

What does Monster Casino's licence history show?

On safety, Monster's licence belongs to ProgressPlay, which drew a £1,000,000 financial penalty in 2025.

Monster is a white label, so every Gambling Commission action against ProgressPlay sits on the licence your account depends on. There have been 2 in 4 years, with an advertising ruling in between:

• 17 May 2022: a £175,718 regulatory settlement over social responsibility and anti-money laundering failures
• 8 May 2024: the Advertising Standards Authority ruled against ProgressPlay, trading as JeffBet, over a "New Players Only" welcome that meant new to the whole network
• 9 May 2025: a warning, the £1m financial penalty and a third-party audit within 6 months, for failings between August 2021 and August 2024

That network-wide eligibility rule the ASA objected to is still in Monster's terms today. It means a sister's welcome can count against yours.

How far do ProgressPlay's limits and self-exclusion reach?

You can set deposit, wager and loss limits, a monthly net deposit limit, time-outs of up to 42 days and reality checks. Those limits apply across every account you hold in the network.

The terms also bar anyone registered with GAMSTOP, or anyone who has self-excluded from another account in the network. Monster's terms say any self-exclusion or time-out set here holds on every website ProgressPlay operates. Until the exclusion ends, keep away from Bluefox, JeffBet and the other sisters as well.

Monster's terms give a 6-month to 5-year range for the exclusion, but its safer gambling page shortens that to 6 to 12 months. GAMSTOP's own range runs the full 6 months to 5 years. Its block carries on past the end date unless you ask GAMSTOP to remove it, for as long as 7 more years before it is deactivated.

Complaints follow the terms' process, with eCOGRA as the free dispute service after 8 weeks, although the site footer still links to IBAS. GamCare runs the National Gambling Helpline on 0808 8020 133, free, if gambling is causing harm. You must be 18 or over to play, and more support sits on the responsible gambling page.
