William Hill Sister Sites: Casino and Betting Brands Compared

William Hill’s sister sites are the other brands run by its parent group, Evoke plc (the company formerly called 888 Holdings): 888casino, 888sport, 888poker and Mr Green. William Hill’s online arm is operated by WHG (International) Limited under UK Gambling Commission account number 39225, and the sister brands sit under the same group, each UKGC licensed in its own right. What they don’t share is one bonus or one game lobby, so the welcome offer, software mix and loyalty scheme differ from brand to brand.

William Hill Sister Sites in Full

A quick note on what counts. William Hill’s own site lists its localised, country-specific versions (the .com, the Italian and Spanish editions and so on) as part of the same brand family. This page uses the wider meaning that most UK searchers have in mind: other gambling brands run by the same operator group. By that definition the related brands are the Evoke plc casinos, namely 888casino, 888sport, 888poker and Mr Green.

Best Sister Sites at a Glance

• Best overall for casino players: 888casino, the group’s flagship online casino with a far bigger slots and live-dealer library than William Hill’s Vegas section.
• Best for sports bettors: 888sport, which shares William Hill’s sportsbook heritage but leans into bet builders and price boosts.
• Best for card players: 888poker, one of the few standalone poker rooms still run by a major UK group.
• Best design-led casino: Mr Green, a Malta-born brand with a cleaner, more modern feel than the William Hill lobby.

William Hill Sister Sites Compared

Which William Hill Sister Site Should You Choose?

Stay with William Hill if sport and the familiar bookmaker feel are the point. Choose 888casino for a casino lobby with more weight behind it, 888sport for an online sportsbook comparison, 888poker when poker is the actual priority, and Mr Green if a cleaner casino-first experience is what you want. They share a wider corporate relationship, but they are different products with their own account, bonus and withdrawal terms.

888casino

888casino is the natural first stop if you came to William Hill for the slots rather than the football. It’s run within the same group, Evoke plc, and licensed in Great Britain through 888 UK Limited, so you get the same regulatory protection and GamStop coverage. Where it pulls ahead is the casino itself: a much larger slots catalogue, a fuller Evolution-powered live-dealer floor, and 888’s own exclusive tables and games that William Hill doesn’t carry. Payments cover the usual debit cards, PayPal and bank transfer, with the same kind of low minimums you’ll know from Hill’s. Versus William Hill: think of 888casino as the casino-first version of the same company, without the retail and sportsbook baggage.

888sport

If it’s the sportsbook you rate at William Hill, 888sport is the closest sibling. Same parent, same 888 UK Limited licence, and a similar spread of football, racing, tennis and the rest. The difference is positioning rather than protection. 888sport tends to push bet builders, acca tools and regular price boosts harder than William Hill does, and it has no high-street estate behind it, so it lives and dies online. Versus William Hill: a leaner, promo-led sportsbook from the same stable, handy if you want a second account for boosted prices and best-odds-style offers.

888poker

888poker is the group’s dedicated poker room, and it’s worth singling out because William Hill’s own poker offering has shrunk over the years. Run under the same Evoke group and 888 UK Limited licence, it gives you cash games, tournaments and the softer-than-average fields 888 is known for. The casino and sportsbook crossover is there if you want it, but poker is the point. Versus William Hill: this is the brand to use when you actually want to sit at a table rather than spin a slot, something the main William Hill site no longer does as well.

Mr Green

Mr Green is the odd one out in a good way. It started life as a Malta-based casino, was bought by 888 in 2019, and now sits inside Evoke plc alongside William Hill. In Great Britain it’s licensed through Mr Green Limited, so it’s a genuine same-group sister with full UKGC and GamStop coverage. The draw is the experience: a cleaner, more modern lobby, a strong slots and live-casino range, and a design that feels a generation newer than William Hill’s Vegas pages. Versus William Hill: same owner, very different mood, and the one to try if the William Hill interface feels dated to you.

The Evoke Network in Full

The brands above are the ones most UK players will recognise, but the wider Evoke plc family is a little bigger. Unlike a white-label platform that rents its licence to dozens of third-party skins, Evoke owns and runs its brands directly, which keeps the list short and verifiable.

• Owned UK brands: William Hill (sports, casino and retail), 888casino, 888sport, 888poker and Mr Green.
• Regional and non-UK brands: Evoke also runs localised William Hill and 888 sites for other markets, plus Winner.ro in Romania. These sit outside the UK licence and aren’t covered by GamStop, so they’re not alternatives we’d point a UK player towards.

Operator and ownership details do change, especially right now, so treat any list as a snapshot. The reliable way to check a brand is genuinely related is to look up its licensed operator on the operator details shown in the casino footer: William Hill online shows as WHG (International) Limited under account number 39225, and the 888 and Mr Green brands show their own 888 UK Limited and Mr Green Limited entries within the same group.

Are These Official Sister Sites?

It’s worth separating three things people lump together. First, there are William Hill’s own official versions, the localised .com and country sites run by the same brand. Second, there’s the same-group network, the other Evoke plc brands like 888casino and Mr Green, which is what this page covers and what most people mean by sister sites. Third, there are unrelated casinos that simply look similar or get suggested as alternatives. Only the first two are genuinely connected to William Hill, and only UK-licensed ones come with GamStop protection.

Our Full Review

William Hill is one of the oldest names in British betting, founded in 1934 and online since the early days of internet gambling. These days the online business is run by WHG (International) Limited and owned by Evoke plc, the group that was 888 Holdings until a 2024 rebrand. It’s a sportsbook first and a casino second, and that order shows up everywhere on the site.

Welcome Offer

The headline casino offer for new UK players is 200 free spins on Big Bass Splash. You opt in, deposit and stake 10 pounds, and the spins land at 10p each, which is 20 pounds of spin value, with winnings capped at 30 pounds and the free-spin winnings carrying a 10x wagering requirement. There’s a smaller 50-spin version on a different game too. On the sports side the long-running deal is bet 10 pounds, get free bets, with no wagering on the free bets themselves. One thing worth knowing: since 19 January 2026 the UK Gambling Commission has capped bonus wagering requirements at 10 times for all licensed operators, so if you see an old review quoting 35x or 40x on a William Hill bonus, that figure is out of date. Always check the current terms on the promotions page before you opt in.

Games and Providers

The casino runs over a thousand games, with the slots you’d expect from the big studios and a live-dealer floor powered by Evolution covering roulette, blackjack, baccarat and game-show formats like Crazy Time. It’s a solid library, but it’s noticeably smaller than what you get at a casino-first brand, including the group’s own 888casino. The old William Hill Casino has been folded into the Vegas section, which is where most of the slots now live.

Payments and Withdrawals

Banking is straightforward: debit cards, PayPal, Apple Pay and bank transfer, with low minimums around 5 pounds. Worth noting that the welcome bonuses tend to restrict eligible payment methods to debit cards and instant bank transfer, so an e-wallet deposit can void the offer. A genuinely useful quirk is the retail tie-in, you can pay into or withdraw from your online balance over the counter in a William Hill shop.

Support and Safer Gambling

Support centres on 24/7 live chat, backed by a help centre and social channels. There’s no widely advertised casino support phone line, which is a gap if you prefer to talk things through. On safer gambling, William Hill is UKGC licensed and therefore part of GamStop, with deposit limits, time-outs and self-exclusion built in. It’s only fair to be honest about the record here, though: the Gambling Commission fined William Hill firms 6.2 million pounds in 2018, and in 2023 took a then-record 19.2 million pound action across three group companies, of which WHG (International) Limited settled 12.5 million pounds for anti-money-laundering and safer-gambling failures between 2020 and 2021. Part of that case involved 331 customers who had self-excluded with sister brand Mr Green still being able to gamble. A further small penalty of about 83 thousand pounds followed in August 2025. The brand has changed senior staff and tightened controls since, but it’s a history a careful player should know about.

Mobile

There are William Hill apps for both sports and Vegas on iOS and Android, and the mobile site works fine in a browser too. The app handles betting and slots cleanly enough; the casino just inherits the same slightly dated feel as the desktop lobby.

How It Compares to Its Sister Sites

Set against the Evoke family, William Hill is the all-rounder with the retail heritage, while 888casino is the better pure casino and Mr Green is the better-looking one. If you mainly bet on sport, you’ll be happy here. If you came for slots and live tables, the honest answer is that one of its own sister sites probably serves you better.

Pros and Cons

Pros

• One of the most established UK operators, with a UKGC and Gibraltar licensing setup and full GamStop coverage.
• Genuinely useful retail tie-in, you can top up or cash out at a William Hill shop counter, which most online-only rivals can’t match.
• Strong, sport-led platform with a deep sportsbook and a competent Evolution live-casino floor.
• Low entry point, with deposit and withdrawal minimums around 5 pounds and no fees on standard methods.

Cons

• Casino library is smaller and the lobby feels dated next to casino-first brands, including its own sister 888casino.
• Thin ongoing promotions for existing players, and welcome bonuses restrict which payment methods qualify.
• A real regulatory history: a 2018 fine and a 2023 settlement for anti-money-laundering and safer-gambling failures, including a self-exclusion gap with sister brand Mr Green.
• Public review scores are poor, with a Trustpilot average around 1.2 out of 5 from roughly 6,900 reviews, and there’s no casino support phone line.

Frequently Asked Questions

Who owns William Hill?

William Hill is owned by Evoke plc, the group that was called 888 Holdings until a 2024 rebrand. The online business is run by WHG (International) Limited under UK Gambling Commission account number 39225. As of writing, Evoke is in takeover discussions with Bally’s Intralot, so ownership could change later in 2026.

What are William Hill’s sister sites?

The main William Hill sister sites are the other Evoke plc brands: 888casino, 888sport, 888poker and Mr Green. They share the same parent group and UK regulation, but each runs its own welcome offer, game range and loyalty scheme.

Are William Hill’s sister sites on GamStop?

Yes. Every UK-licensed brand in the Evoke group, including 888casino, 888sport, 888poker and Mr Green, is covered by GamStop, so a self-exclusion through the scheme applies across all of them.

Is 888casino a William Hill sister site?

Yes. 888casino sits under the same parent group as William Hill, Evoke plc, although it holds its own UK licence through 888 UK Limited rather than William Hill’s WHG (International) licence. For casino players it’s the strongest brand in the group.

Are Mr Green and William Hill sister sites?

Yes. Mr Green was bought by 888 in 2019 and now sits inside Evoke plc alongside William Hill. In Great Britain it is licensed through Mr Green Limited, with full UKGC and GamStop coverage, and it has a more modern, design-led feel than William Hill.

What is the best William Hill sister site?

For most players the best William Hill sister site is 888casino, because it offers a much larger slots and live-casino range than William Hill’s Vegas section while keeping the same group ownership and UK protection. If you prefer a cleaner, more modern casino, Mr Green is the pick.

Has William Hill been fined by the Gambling Commission?

Yes. The Gambling Commission fined William Hill firms 6.2 million pounds in 2018, and in 2023 took a then-record 19.2 million pound action across three group companies; WHG (International) Limited’s share was a 12.5 million pound settlement for anti-money-laundering and safer-gambling failures, including letting customers who had self-excluded with Mr Green keep gambling. A further small penalty followed in 2025. The brand has since changed staff and tightened controls.

What is William Hill’s casino welcome offer and wagering requirement?

The current casino offer for new UK players is 200 free spins on Big Bass Splash after you stake 10 pounds, with winnings capped at 30 pounds and a 10x wagering requirement on free-spin winnings. Since 19 January 2026 the UKGC has capped bonus wagering at 10 times for all licensed casinos, so older figures like 35x are out of date. Always check the live terms before opting in.

Does William Hill still have betting shops?

Yes, although the estate is shrinking. Evoke announced the closure of around 200 William Hill shops in 2026 in response to higher gambling taxes. The shops that remain still let you pay into and withdraw from your online account at the counter.

Our Verdict on William Hill

William Hill is a dependable, properly licensed operator that’s strongest if you’re here for the sport. The casino works, but it’s the secondary act, and the dated lobby plus a real regulatory history keep it short of the top tier. The pick for me among the William Hill sister sites is 888casino, which gives you the same group’s protection with a far better casino, while Mr Green wins on looks. Use William Hill for betting and the retail tie-in; switch to a sister for slots.
