The ProgressPlay connection
Monster Casino and Casino Kings carry the same footer, apart from the brand name. Each says it is operated by ProgressPlay Limited, a company registered in Malta (C58305), licensed by the Malta Gaming Authority under MGA/B2C/231/2012 and ‘licensed and regulated in Great Britain by the Gambling Commission under account number 39335’. The same company, registration and account number are the connection this guide records. Both welcome offers also mention ‘brands within the network’, so do not take this pair as ProgressPlay’s full list; it is the two whose own pages we have read.

The network limit on welcome offers
That network shows in the offer small print. Monster Casino’s casino welcome terms include the line ‘Limited to 5 brands within the network’, and Casino Kings’ carry the same line. It is not explained further. The natural reading is a cap on how many of the network’s casinos you can take the welcome offer at, so do not count on a fresh new-player deal at every sister. Both offers also exclude Skrill and Neteller deposits, and both say ‘Withdrawal requests void all active/pending bonuses’.

Compare the cash-conversion caps
The headlines differ more than the conditions. Monster Casino advertises a ‘Welcome Package Up To £1000 + 100 Free Spins on Starburst’, with 10x wagering on the bonus within 30 days and on free-spin winnings within 7 days. Its maximum conversion is £50 from the bonus amount or £20 from free spins. Casino Kings advertises ‘Deposit £20 + Get 100 Free Spins’, with 10x wagering on spin winnings within 7 days and a £30 maximum conversion. Judge them on what can become withdrawable cash, not the headline figure.

Apps, support and phone payments
A few practical differences show on the casinos’ own pages. Monster Casino’s homepage links an Android app on Google Play; Casino Kings’ links an iPhone app on Apple’s App Store. Monster’s pay-by-phone page says most phone-bill deposits are limited to £30 a day, the Boku minimum is £15, ‘When you use Boku, a fee of 15.00 % is charged from the deposits made via phone bill’, and phone billing cannot be used to withdraw. Monster says its live chat is available 24/7; Casino Kings says the same for logged-in customers.

Where withdrawal information is missing
One gap to know about. Monster Casino’s sign-up, terms, and deposit and withdrawal pages sit on a different address, games.monstercasino.com, which its monstercasino.co.uk homepage links to. We could not read those pages, so this guide does not yet give Monster’s withdrawal times, limits or fees. Casino Kings publishes a £5 minimum withdrawal and a fee of ‘1% up to £3 per withdrawal’, but those are Casino Kings’ terms. Do not assume Monster’s are the same.

A closer look
A closer look at the sister sites
The same owner, with each casino’s homepage and its own research record.
Casino Kings is operated by ProgressPlay Limited, establishing its company connection with Monster Casino. That relationship is useful for comparing network rules, while the welcome offer remains specific to Casino Kings. The captured promotion focuses on free spins rather than the larger package headline used by Monster. Looking at the qualifying deposit, treatment of spin winnings and conversion cap gives a more meaningful comparison than placing the two headline rewards side by side.
Paragraph sources
- From www.casinokings.com/, read 8 Sept 2026.
The recorded welcome offer is 100 free spins with a £20 deposit. Free-spin winnings carry a wagering requirement of 10 times, a seven-day expiry and a £30 conversion cap. The cap matters because the number of spins does not describe an unrestricted cash balance. Selected games qualify and their wagering contributions vary, so the specific game rules should be read alongside the multiplier and deadline.
Paragraph sources
- From www.casinokings.com/, read 10 Sept 2026.
Skrill and Neteller deposits are excluded from the promotion. Eligibility is limited to five network brands, and requesting a withdrawal voids active or pending bonuses. These conditions are particularly relevant in a sister-site comparison: opening a differently branded website does not itself establish fresh eligibility for every network offer. The method used to fund the account and any previous network promotions therefore need to be considered with the stated offer conditions.
Paragraph sources
- From www.casinokings.com/, read 10 Sept 2026.
The recorded general deposit minimum is £20 and the withdrawal minimum is £5. Withdrawal timing varies by payment method, and further identity checks may be required. A processing fee may apply, capped at £3 per transaction. Identity and age verification are required before depositing or playing. These details provide specific banking comparison points without claiming a fixed withdrawal speed that the captured terms do not support.

- From www.casinokings.com/terms-and-conditions, read 10 Sept 2026.
The account rules describe one account at this site; they do not establish shared login access across sister brands. Account eligibility also requires that the player has not self-excluded from another account in the Company Network. That condition should be considered before treating Casino Kings as an independent alternative to another ProgressPlay casino. Different branding does not, by itself, change the network eligibility wording.
Paragraph sources
- From www.casinokings.com/terms-and-conditions, read 10 Sept 2026.
Casino Kings advertises more than 4,000 games. This is the operator’s published catalogue claim, rather than an independently counted current total. Live chat is stated to be available 24 hours a day for logged-in customers. When comparing game choice, checking a particular title and its bonus contribution is more informative than relying solely on the catalogue total, especially where the welcome spins and eligible games have specific conditions.

What the terms say
What do the terms say about UK players?
Monster Casino: we have not read its terms.
We cannot establish its UK status until we have read the terms.
This describes the casino’s country restrictions, not its licensing status. An offshore licence does not establish authorisation to serve players in Great Britain. How we distinguish these checks.
How we check UK termsMonster Casino sister-site questions
Is Monster Casino related to Casino Kings?
Yes. Their own disclosures name ProgressPlay Limited, registration C58305, as the operating company. The ownership sources are listed below.
Can I use the same account at its sister sites?
Shared-account rules are not yet verified. A shared owner alone does not establish that one login works at another casino.
Do all the sisters have the same offer?
Shared ownership alone does not establish matching offers. Compare each casino’s own terms, including eligibility, qualifying deposit and wagering base, in the tables above.
