The Online Casino Sister Sites

The Online Casino sister sites are Mr SuperPlay, PlayUK and Casino Palace, and the remaining brands on that UK licence account sit with them in the register.

The Online Casino operates under a UK Gambling Commission licence held by ProgressPlay Limited, account 39335, according to the register checked 10 November 2026. The on-site spelling is "TheOnlineCasino". Official GAMSTOP guidance brings in every online gambling company licensed in Great Britain, so the same licence carries that coverage. Gambling carries financial risk, and this page is for adults aged 18 and over.

The Online Casino Sister Sites 2026

Figures below follow a 10 November 2026 register check.

The Online Casino is a.co.uk-branded white label at the consumer host, with the UK welcome read on the UK play host. Licence sisters are the other domains on the operator, UK Gambling Commission account 39335, checked 10 November 2026 (Europe/Stockholm). Twenty Active domain rows appear on that extract, as a row count rather than a collapsed brand figure, and this site is a White Label. Self-exclusion with the licensee covers all gambling with this licensee unless the request was limited, and the national self-exclusion scheme applies across GB-licensed online sites (LCCP social responsibility code 3.9.1). The prep trio used Jackpot.com, PlayUK and Casino Palace. Jackpot.com has been removed: a UK check, checked 11 November 2026 found www.jackpot.com is no longer a UK casino (it redirected to a US lottery courier, with no casino navigation and no UKGC text). Mr SuperPlay replaces it. PlayUK and Casino Palace stay. Bonus figures remain our UK checks checked 10 November 2026. PlayUK was re-checked on the 11 November 2026 UK pass; those the recorded values are kept, and conflicts are recorded in comments, not chosen.

Already-published reviews on this licence account, listed here as TangoBet first, are: TangoBet, DynoBet, Betmaze and Red Axe Play. TangoBet, DynoBet, Betmaze, Red Axe Play and the operator.

House-brand drafts are on the operator hub.

The Online Casino is for adults (18+). Keep it as leisure rather than a way to make money. Changing sister does not lift an exclusion. Support is at BeGambleAware, GamCare — helpline 0808 8020 133, and 0808 2819 265 in Wales — the national self-exclusion scheme and the responsible gambling page.

How the sisters compare

These four casinos sit on the same ProgressPlay Limited UKGC account, 39335 (Gambling Commission public register, viewed November 2026). The table is the UK view recorded in November 2026.

What really differs is the shape of each welcome and the standout product feature on each site. Where a casino's own UK pages disagree on the welcome, no version has been chosen.

The Online Casino Review

theonlinecasino.co.uk was live when we loaded it from Great Britain on 11 November 2026, showing a black and neon-green marketing site with a green logo, Book of Dead artwork, provider and RTP labels on the game cards, sports fixture cards and a Google Play download area. This review sets out what that site and its network pages actually print, and where the gaps are.

Licence, operator and regulator

The TheOnlineCasino site runs on another company’s licence. The register checked 10 November 2026 lists theonlinecasino.co.uk as a White Label row under ProgressPlay Limited, and the footer read from Great Britain names the same account.

The licensee’s record with the regulator:

• An earlier £175,718 settlement, 17 May 2022, according to the Commission.
• The Commission’s August 2025 article places the failures between August 2021 and August 2024 and cites anti-money-laundering conditions 12.1.1 and 12.1.2 and customer-interaction code 3.4.3.
• 9 May 2025: a formal warning, an added audit condition and a £1,000,000 financial penalty (listed on the actions page, checked 10 November 2026).

Sign-up bonus terms

Two different welcomes sit behind one promotions link: switch to Sports and the casino match is replaced by a free bet. Both were checked on 11 November 2026.

Casino welcome:

In numbers, according to the T&Cs: a deposit of €50 earns all of the €50 at 100%, and 10x on that bonus means €500 of qualifying bonus bets before it can convert.

Sister offers side by side

Next to The Online Casino’s own headline, 100% up to €50 + Free Spins (welcome terms, checked 11 November 2026), the other cards above show:

• PlayUK: Differs between the casino's own pages; check its promotions page (casino site, checked 11 November)
• Mr SuperPlay: Get 150% Bonus up to €50 + 15 FS, 10x (casino site, checked 11 November)

Because the welcome terms are limited to five brands in the network, claiming several of these in turn is not open-ended.

Reload offers and loyalty

Beyond the welcome offer, the promotions list checked from Great Britain on 11 Nov 2026 showed these running offers:

• MBOX deposit code for the Mystery Box, promising “Unbox up to 100 Free Spins!” (checked 11/11/2026)
• Deposit code RA25 for up to 75 Free Spins, three uses allowed — checked 11 Nov
• Midweek Wheel of Prizes and Weekend Wheel Of Spins — checked 11 Nov
• November Reels & Rewards, billed as “Claim 3X: Up to €250 Bonuses + 105 Free Spins” (checked 11 Nov)

A sister account will usually show the same network campaigns.

The loyalty page (checked 11/11/2026) lists leaderboards, missions and levels with badges and a Rewards Store where points buy Free Spins, Deposit Bonuses, Cashback deals and extras; the wording is shared across the network.

Slots, live casino and other products

Based on the UK view of the site, the product mix is:

• Catalogue claim: “2,000+ CASINO GAMES” in one place and “more than 2,500 games to choose from” in another (homepage, checked 11 Nov 2026); no independent count was made.
• Structure: live Casino, Bingo and Sports are in the marketing header and sidebar and in the linked platform (checked 11 November 2026).
• Sports betting: the site doubles as a sportsbook (homepage, checked 11 November).
• Named games: Book of Dead, Big Bass Bonanza (checked 11/11/2026).

Providers named on the site itself: NetEnt, Microgaming, IGT, NYX, Evolution, Extreme Gaming Studios. No full provider directory is published, so no studio count is given here.

For RTP, the payout percentages page is the place to look. Checked 11 November 2026, it listed Starburst 93.05%, Book of Dead 91.25%, Fluffy Favourites 90.19%. It covered around 4,107 games, as published by the site rather than tested here.

Payment methods, limits and payout times

Ten deposit methods are listed on the TheOnlineCasino deposits page, checked 11 November from Great Britain, all marked “Instant”; limits the page leaves out are shown as not stated.

Cash-outs take one business day of processing and then a transfer period, according to the payouts page read 11 November 2026:

The spread is wide: about two business days end to end for Skrill, NETeller or Instant Bank Payment, against four to eight for a debit card or PayPal (Cashing Out page, checked 11 November 2026).

Before requesting a withdrawal, note:

• Mastercard cannot be used for payouts because the card issuer restricts it (payouts page).
• Fee: 1% of each withdrawal, with a ceiling of €3, according to the cash-out page checked 11/11/2026.
• PayviaPhone deposits lose 15% to a processing fee and offer no withdrawals (deposits page).
• A pending deposit may slow a withdrawal until final approval (cash-out page).

Per-transaction limits come from the payments policy on the The Online Casino site (checked 11 November 2026):

• Deposit floor: €20 for Skrill, Neteller, Ecopayz (Payz); €15 for NeoSurf; €10 for Apple Pay, Paysafecard, PayPal, Instant Bank Payments, Visa / Mastercard debit, PayViaPhone (source).
• Deposit ceiling: €5,000 (Apple Pay, PayPal, Instant Bank Payments, NeoSurf, Skrill, Neteller, Visa / Mastercard debit, Ecopayz (Payz)); €700 (Paysafecard); €40 (PayViaPhone) (policy).
• Payouts: €5–€3,000 per transaction; NeoSurf and PayViaPhone cannot receive them (source).
• Restrictions: Apple Pay: no credit cards; Instant Bank Payments: payouts only after a successful deposit; Visa / Mastercard debit: debit cards only; PayViaPhone: €240 a month cap; 15% fee taken from each deposit (policy).

• Small balances: ask Customer Support and the whole balance can be paid out, according to the T&Cs (checked 11 November 2026).
• Mismatch: the deposit information page asks €20 for Instant Bank Payments while the payments policy says €10 (checked 11 Nov); The Online Casino has not reconciled the two.
• The payments policy groups Visa and Mastercard in one row, but the cash-out page says “MasterCard credit and debit card withdrawals are not available due to issuer restrictions.” (checked 11/11/2026).
• No cancelling: “You are not permitted to cancel a withdrawal for any reason”, and requests show as “Pending” until paid (terms, checked 11 November 2026).

Opening an account and ID checks

The ID and address documents listed below comes from the shared network-wide terms as shown on the Yoko Casino T&Cs (checked 11/11/2026); the The Online Casino terms themselves (version 1.2.17, dated 21 May 2026, checked 11 November 2026) were read for the verification rule and the dormant-account fee.

1. Identity: a passport, driving licence or national ID card, according to the network T&Cs checked 11 Nov 2026.
2. Age and ownership: you must be at least 18 and each payment method must be in your own name (network T&Cs).
3. Payment card: images of both sides of the debit card you deposit with (network T&Cs).
4. Proof of address: a utility bill or card statement dated in the last three months (network T&Cs).
5. Further checks: the licence-holding company may ask for proof of source of funds or wealth whenever it needs to (network T&Cs).
6. When: the account needs ID and age verification before any deposit or play (terms).

One cost to know about: dormancy. According to the T&Cs v1.2.17 checked 11 November 2026, an account unused for 12 months is dormant, and after a refund attempt and 30 days’ notice a €5 monthly fee can run the balance down to zero.

Safer gambling: limits and breaks

The tools below are set out on the TheOnlineCasino safer-gambling page, read from Great Britain on 11 November 2026:

Any limit change only take effect 24 hours after the request, as set out in the shared terms. Outside help: GamCare and BeGambleAware, both free and confidential.

A limit set here also binds every other account in the same network, and the periods roll: the last 24 hours, the last 7 days and the last 30 days, according to the responsible gaming page checked 11 November.

From the help and banking pages checked 11 Nov:

Playing on mobile

What can be said about mobile without guessing:

• Rewards: progress is tracked “from the menu on your mobile device”, according to the network Rewards wording.
• The pages were read on desktop; a phone session was outside this check.
• App: a Google Play download area on the marketing homepage was shown on the homepage on 11 November 2026; the app itself was not installed or tested.
• Pay by phone bill: PayviaPhone is on the casino cashier list, but it carries a 15% fee and does not accept withdrawals (deposit information page).
• Check the cashier screen on the phone itself, since payment options can show differently by device.

Pros and cons

Strengths and weak spots of The Online Casino:

Is The Online Casino Legit? Our Verdict

On the licensing test, yes. The register checked 10 November 2026 shows theonlinecasino.co.uk as White Label under ProgressPlay Limited, which brings GAMSTOP and the Commission’s rules with it.

What to keep in mind:

• The offer: 100% up to €50 + 20 Free Spins on Big Bass Bonanza at 10x wagering, according to the welcome terms checked 11 Nov 2026.
• Every cash-out costs 1% up to €3 according to the withdrawal information page, and cards or PayPal can take four to eight business days in total.
• The licensee’s £1,000,000 penalty in 2025, recorded on the licence register, counts against the group, even though the licence stays in force.
• The marketing banner and the detailed terms do not always match; the detailed terms are the ones that apply.
