Interbet Sister Sites: The ProgressPlay Casino and Betting Network

Interbet is run by ProgressPlay Limited, so its sister sites are the other casinos and sportsbooks on the ProgressPlay platform, names like Casino Kings, JeffBet, Spinzwin, Dazzle Casino, Glimmer Casino and Kingdom Ace. They share the same UK Gambling Commission licence (account 39335), the same Maltese licence and the same white-label back office, with the main differences being the welcome offer, the front-end design and whether a brand bolts on sports betting like Interbet does.

The ProgressPlay Network in Full

A note on terminology. ProgressPlay is a white-label platform, so most of its “brands” are third-party-branded skins sitting on one shared licence rather than a tidy family of official Interbet spin-offs. On this page “sister site” means another brand on the same ProgressPlay operator and the same UKGC licence as Interbet. That is the link that actually decides your bonus terms, your KYC and your self-exclusion, far more than which logo is on the homepage.

Best Interbet Sister Sites at a Glance

• Best overall: Casino Kings, ProgressPlay’s flagship with the biggest game library.
• Best for sports bettors: JeffBet, the closest match to Interbet’s casino-plus-sportsbook mix.
• Best for slots: Spinzwin.
• Best established skin: Dazzle Casino.
• Best familiar name: Glimmer Casino.
• Best simple alternative: Kingdom Ace.

Interbet Sister Sites Compared

The sister sites worth knowing

Casino Kings is ProgressPlay’s premium brand and the obvious step up from Interbet. Same operator, same UKGC and MGA licences, but a much deeper catalogue, over 3,000 games from 40-plus providers across slots, table games, live casino, sports and bingo, plus an iOS app that launched in early 2025 and 24/7 live chat. Versus Interbet it is the same back office with far more on the shelves.

JeffBet is the closest match to what Interbet actually is, a casino bolted onto a sportsbook. It is a ProgressPlay brand on the same 39335 licence, with a clean modern build after a platform refresh and a reputation for paying out promptly. If you came to Interbet mainly for the betting side, JeffBet is the natural sister to try.

Spinzwin drops the sportsbook and leans into slots. Same platform, same payment rails, same support, just a slot-first front end. A sensible swap if you only want the casino part of Interbet.

Dazzle Casino is one of the longer-running ProgressPlay skins. Nothing flashy, but it is a stable, established brand on the same licence, useful if you prefer a name that has been around a while.

Glimmer Casino and Kingdom Ace round out the shortlist as familiar casino-only skins on the same engine. Underneath, the games, the wagering and the support are shared with Interbet. The wider network is large, ProgressPlay runs roughly 95-plus live brands, so Power Slots, Betarno and many more sit on the same platform too.

The Complete ProgressPlay Sister Sites List

ProgressPlay has held a UKGC licence since November 2014 and runs one of the bigger white-label networks aimed at UK players, with counts of around 95 to 133 live brands depending on the source. Roughly:

• Flagship/active casino brands: Casino Kings, Spinzwin, Dazzle Casino, Glimmer Casino, Kingdom Ace, Betarno.
• Sports-led brands: JeffBet and Interbet itself, casino plus sportsbook.
• White-label skins: a long tail of third-party-branded sites on the same 39335 licence, with some carrying their own separate licences.

Some inactive ProgressPlay domains still float around on old affiliate lists, so treat any “full list” as a snapshot and confirm a brand against account 39335 on the UK Gambling Commission register before trusting it.

What’s the Same and What’s Different

Are These Official Interbet Sister Sites?

Three groups people conflate. There is no separate “official Interbet” brand-family, Interbet is one skin on a big platform. The same-operator network is every ProgressPlay brand on the 39335 licence, which is what this page covers. And there are unrelated white-label casinos that simply look similar because the white-label template style is common, those are not sisters. The footer T&Cs, naming the operator and the UKGC account, settle it every time.

Betmaze

Betmaze is the most recent ProgressPlay brand to be reviewed here. Like Interbet it runs betting and casino together rather than choosing one, and it covers football, basketball, cricket, rugby, tennis and horse racing. It also ships apps on both mobile stores, which few skins on this licence do. Betmaze is shown below.

Interbet Review

Operator details last reviewed: June 2026 (last updated 8 June 2026)

Updated June 2026: confirmed the ProgressPlay operator and UKGC account 39335, added the operator’s 2022 and August 2025 UKGC enforcement actions, and set wagering to the current UK 10x cap.

Welcome offer and promotions

Interbet runs two welcomes because it is two products. The casino side offers a 100% match up to about £200, and the sportsbook gives a small free bet (around £10) on a qualifying first bet. Casino bonus wagering is 10x, in line with the UK cap from 19 January 2026; ProgressPlay sites historically quoted much heavier multiples like 50x, but those do not apply to UK players now. Read the per-product terms, the sports and casino offers have different rules.

Games and providers

The casino carries 600-plus games from 50-plus providers, slots front and centre, with table games, live dealer, jackpots, scratchcards and a few bingo titles. The sportsbook covers the mainstream sports plus solid eSports and some novelty markets. It is a broad, no-frills offering rather than a specialist in any one area.

Payments and withdrawals

Standard ProgressPlay banking: debit cards and the usual e-wallets, with a £10 minimum on most offers (Skrill and Neteller are sometimes excluded from bonuses). Withdrawal speeds are middling; ProgressPlay brands are not known for fast payouts, and a small withdrawal fee can apply on some sister sites.

Support and responsible gambling

Support is live chat and email. Because Interbet is UKGC-licensed it carries the full safer-gambling toolkit, deposit limits, time-outs and GamStop, and a GamStop registration blocks every ProgressPlay brand on the 39335 licence at once. That said, the operator’s record here is a real concern, see Cons. GamCare and BeGambleAware are the independent places to get help.

Mobile

No dedicated app, but the site is fully mobile-optimised and works the same on a phone as on desktop. Some sister brands (Casino Kings) do have an app if that matters to you.

How it compares to its sister sites

Interbet sits in the middle of the ProgressPlay range: more than a bare-bones casino skin because of the sportsbook, but well short of the flagship. If you want the betting-plus-casino combo with a fresher build, JeffBet is the natural swap; if you want depth, Casino Kings is the bigger, better-stocked sibling.

Interbet Key Facts

Pros and Cons

Pros

• Dual UKGC and MGA licensing, so GamStop, deposit limits and IBAS dispute cover all apply.
• One account gets you both a 600+ game casino and a full sportsbook with strong eSports coverage.
• 10x casino bonus wagering under the UK cap, lighter than ProgressPlay’s historic multiples.
• Part of a large, long-established network (licensed since 2014), so the platform itself is stable.

Cons

• ProgressPlay has two UKGC enforcement actions on record: a £175,718 settlement in 2022 and a £1,000,000 fine in August 2025, both for anti-money-laundering and social-responsibility failings. That is the single biggest trust concern here.
• Withdrawals are middling and some sister brands apply a small cashout fee.
• No dedicated app; you are on mobile web (unlike flagship sibling Casino Kings).
• Standard white-label design and bonus structure, so little to distinguish it from dozens of ProgressPlay skins.

What are Interbet sister sites?

They are the other ProgressPlay brands on the same licence, including Casino Kings, JeffBet, Spinzwin, Dazzle Casino, Glimmer Casino and Kingdom Ace, with many more across the wider network.

How many sister sites does Interbet have?

ProgressPlay runs roughly 95 to 133 live brands depending on the source, with some inactive domains on older lists. Check account 39335 on the UKGC register for the current set.

Are Interbet sister sites on GamStop?

Yes. Interbet and its ProgressPlay sisters are UKGC-licensed and on GamStop. A single GamStop registration blocks every brand on the 39335 licence at once.

What is the wagering requirement at Interbet?

Casino bonus wagering is 10x, in line with the UK cap in force from 19 January 2026. ProgressPlay sites used to quote much higher multiples like 50x, but those no longer apply to UK players.

What is the best Interbet sister site?

JeffBet is the closest match if you want Interbet’s casino-plus-sportsbook combination with a fresher build, while Casino Kings is the pick for the biggest game library. Both run the same ProgressPlay platform and terms.

Has ProgressPlay been fined by the UKGC?

Yes, twice. ProgressPlay agreed a £175,718 settlement in 2022 and received a £1,000,000 fine in August 2025, both for anti-money-laundering and social-responsibility failings. The licence remains active and corrective measures were required.

Is JeffBet an Interbet sister site?

Yes. JeffBet is another ProgressPlay brand on the same 39335 licence, and like Interbet it pairs a casino with a sportsbook, so it is a genuine same-operator sister site rather than a lookalike.

Our Verdict on Interbet

Interbet is a legitimate UKGC casino and sportsbook, and the dual product is a genuine point in its favour over a plain slots skin. But it is one brand on a very large ProgressPlay network, and the operator’s regulatory record, two UKGC actions including a £1m fine in August 2025, has to weigh on the score. Among the Interbet sister sites I’d steer sports-and-casino players to JeffBet for a fresher build and prompt payouts, or to Casino Kings if you want the deepest library. Interbet itself lands mid-table: solid licensing and a broad offering, dragged down by middling withdrawals and the operator’s compliance history.

BetSuna, a Newer Name on the Same Licence

BetSuna is one of the most recent brands to appear on the ProgressPlay licence that Interbet runs on. Its domain was registered in January 2026 and the site first shows up in the web archive in May 2026, making it a 2026 arrival on paperwork that has been in force since 2014. Its logo is pictured above.

It runs casino, sportsbook and bingo from one account, with a 100% up to €/$100 casino welcome carrying 35x wagering, a €/$50 sports free bet and £20 of bingo money for a £10 deposit. Because it shares Gambling Commission account 39335, the cashier, verification process and complaints route are the same ones you would meet here. Our full BetSuna review lists the wider family.
