21 Casino Sister Sites: The White Hat Gaming Family Compared

21 Casino’s sister sites include Casimba, Playzee, Casilando and Temple Nile, plus newer White Hat Gaming brands like 247Bet, BetTarget, Hopa and Casiku. They all run on the same White Hat Gaming Limited platform and share its UK Gambling Commission licence (number 52894) and Malta Gaming Authority licence, so the verification, terms and game suppliers feel familiar across the family. What changes from brand to brand is the personality: 21 Casino keeps things plain and slot-led with no sportsbook, where some siblings lean into heavy theming, daily promos or, in 247Bet’s case, actual sports betting.

A quick note on what counts as a sister site. White Hat Gaming runs a big platform, so two slightly different groups get lumped together. There’s the tight Casimba Gaming family (Casimba, 21 Casino, Playzee, Casilando, Temple Nile and a few more) that share the same brand owner, and then the wider set of independent casinos that simply sit on White Hat’s UKGC licence 52894. This page uses the common UK search meaning, same operator or shared licence, and flags which bucket each brand falls into so you know exactly what you’re getting.

Best Sister Sites at a Glance

• Best overall: Casimba, the family flagship with the deepest game library.
• Best for promos and personality: Playzee and its Professor Zeegmund theme.
• Best no-frills alternative: Casilando, clean and stripped back.
• Best for theme: Temple Nile, all gold and sandstone Ancient Egypt.
• Best for sports betting: 247Bet, the one sibling with a proper sportsbook.
• Best for casual mobile play: Hopa, with scratchcards and a breezy app feel.

Offers change often and all wagering on UK bonuses is now capped at 10x (see below), so always check the live terms before you opt in.

Casimba

Casimba is the flagship of the Casimba Gaming family and the most obvious step up from 21 Casino. Same operator (White Hat Gaming, UKGC 52894 and MGA), but a much bigger library at well over 3,000 titles from the likes of Pragmatic Play, Play’n GO and Evolution for live tables. Its calling card is a chunky tiered welcome match and a clear VIP track. Payments mirror 21 Casino: cards, PayPal and the usual e-wallets, e-wallet cashouts inside a day or two. Versus 21 Casino, you’re trading 21’s plainer look for a fuller catalogue and a more generous headline offer.

Playzee

If 21 Casino is the quiet one, Playzee is the show-off. It leans hard into its Professor Zeegmund lab theme, with over 2,000 games, a welcome split across three deposits and a Zee Rewards loyalty ladder that actually feels like you’re climbing something. There are daily themed promos (the cheesy named ones) that keep the calendar busy. Same White Hat licence and KYC as 21. The trade-off is personality over restraint: pick Playzee if you want a livelier, busier casino, stick with 21 if you’d rather it stayed out of your way.

Casilando

Casilando goes the opposite way to Playzee. It’s pared back and tidy, roughly 1,800 games, a 100% match plus spins on Book of Dead as the usual welcome, and not much clutter. Providers run to NetEnt, Microgaming and Pragmatic Play. Operator and licence are identical to 21 Casino, so nothing changes on the safety side. The honest difference is size and flash: Casilando is smaller and calmer, which is either a relief or a limitation depending on what you’re after.

Temple Nile

Temple Nile dresses the same White Hat engine in Ancient Egypt, gold, sandstone and the lot. Behind the theme it’s a 2,000-plus game casino with a loyalty scheme and the standard slots-and-live mix. Launched in 2018 under the Casimba Gaming umbrella, so the licence, terms and verification match 21 Casino exactly. Next to 21’s understated style, Temple Nile is the one to choose if you actually want a bit of atmosphere with your spins rather than a plain lobby.

247Bet

247Bet is the newest brand in the family, launched in August 2025 and operated by Casimba Gaming on the same UKGC 52894 licence. Its real point of difference is a proper Altenar-powered sportsbook, which 21 Casino simply doesn’t have, alongside the familiar casino lobby. Football, tennis and horse racing lead the book, with a tidy in-play section. Same White Hat payments and compliance behind the scenes. If you’ve ever wished 21 Casino let you stick a bet on the football, this is the sibling that does.

BetTarget

BetTarget is the multi-tool, bolting a sportsbook onto the casino under one roof on White Hat’s licence 52894. The interface is plain on purpose: straightforward categories, tidy menus, Megaways and slots on the casino side, football, tennis and racing on the sports side. Everything scales neatly to mobile. Live chat can be a touch hard to find. Compared with 21 Casino it’s less polished to look at, but it does the two-in-one job that 21’s casino-only setup can’t.

Hopa

Hopa keeps its mobile-first roots, smooth on a phone and just as happy on desktop. The draw is a cheerful slots-and-scratchcards mix (the scratchcards are a rare touch) plus a decent live casino. It sits on the same White Hat UKGC licence as 21 Casino. The catch is a shortage of big progressive jackpots and promo small print worth reading twice. Against 21 Casino, Hopa is the brighter, more casual option, fine for short sessions on the bus, less so if you chase the seven-figure jackpots.

Casiku

Casiku is one of the newer, smaller names on White Hat’s 52894 licence. It’s minimalist and easy to navigate, with a sensible mix of familiar slots, lesser-known titles and both fixed and progressive jackpots, plus a live casino. The obvious gap is no dedicated app and filtering tools that could be sharper when you’re scrolling hundreds of games. Versus 21 Casino, it’s tidier to look at but thinner on depth, more of a pleasant detour than a permanent home.

The Complete White Hat Gaming Sister Sites List

The network is far bigger than the eight brands above. Broadly it splits three ways.

Same brand owner (Casimba Gaming): Casimba, Playzee, Casilando, Temple Nile, Dream Vegas, Grand Ivy, Jackpot Village, Spin Station, Miami Dice, SpinYoo and 247Bet.

Wider White Hat Gaming licence family (independent brands on the same 52894 licence): 21Prive, Barz, BetTarget, Casiku, GDay Casino, Hello Casino, Hopa, Karamba, PlayGrand, Skol Casino, Slotnite, Slot Planet, Spinland and others.

Treat any list, including this one, as a snapshot. Brands open, rebrand and close, and older affiliate pages still name sites that have gone. The reliable check is the operator name in a site’s footer and its entry on the UK Gambling Commission register: if it reads White Hat Gaming Limited under licence 52894, it’s part of the same regulated family.

Are These Official Sister Sites?

It helps to separate three things people lump together. First, the official Casimba Gaming family: Casimba, Playzee, Casilando, Temple Nile, Dream Vegas, Grand Ivy and the rest, which share 21 Casino’s actual brand owner. Second, the wider White Hat Gaming licence network: independent casinos that aren’t run by the same brand team but do sit on the same UKGC licence 52894, so they share the platform, verification and safer-gambling tools. Third, unrelated casinos that look or sound similar (including lookalike 21 names) but have nothing to do with White Hat. The first two are fair to call sister sites in the everyday UK sense; the third are not, so always check the footer before you trust the label.

Full Casino Review

21 Casino looks sharp without trying too hard, a clean, slot-led lobby with none of the flashing-banner chaos some rivals go in for. Underneath sits the dependable White Hat Gaming framework, the same one powering Casimba, Playzee and the rest. It’s a solid, slightly understated casino that does the basics well, and its main weak spots are the ones the family is known for: cautious withdrawal handling and a thin promo calendar.

Welcome Offer and Promotions

The headline is a 121% first-deposit match up to £300, a neat little flourish on the usual 100% (the extra one per cent plays to the 21 branding). There are no free spins bundled in, which makes it feel a touch plain next to rivals who throw spins on top. On wagering, note the big change: under UK Gambling Commission rules that came into force on 19 January 2026, bonus wagering at all UKGC-licensed sites is capped at 10x, so the old 35x-style figures you’ll still see floating around online no longer apply here. Always read the current terms before opting in. Beyond the welcome, things go quiet: occasional reloads and seasonal bits, plus a loyalty points scheme that converts slowly, like filling a bucket with a teaspoon.

Games and Providers

The library is the strongest part, more than 2,000 titles with slots doing the heavy lifting. Names you’ll know are all here: NetEnt, Play’n GO, Pragmatic Play and Microgaming, with Book of Dead, Starburst and Gonzo’s Quest near the front. Table games cover the blackjack and roulette staples, and Evolution runs a properly polished live dealer suite. What you won’t find is bingo or poker, so if those are your thing you’ll be left wanting.

Payments and Withdrawals

Deposits are simple and instant by debit card, with PayPal, Skrill, Neteller and Paysafecard also supported, and a £10 minimum withdrawal. Cashouts are where 21 tests your patience. E-wallets usually land in 0 to 2 days, but card and bank withdrawals run 1 to 5 working days, and there’s a review window of roughly 24 to 72 hours before anything is processed. First withdrawals take longer while ID, address and payment checks clear, so the smart move is to verify your account up front rather than at cashout.

Support and Responsible Gambling

Support is 24/7 live chat plus email, no phone line. Staff are generally quick and polite, though players report slower, less communicative replies once a withdrawal or verification query is involved. On safer gambling, the usual UKGC tools are built in: deposit limits, time-outs and self-exclusion, plus links to help. As a UKGC-licensed brand, 21 Casino is fully covered by GamStop, the national self-exclusion scheme. There’s guidance to GamCare and BeGambleAware too.

Mobile Experience

There’s no app to fuss with; it runs in the phone browser and the games reflow cleanly to the screen. We tried a handful of slots on a phone and they were as crisp as on a laptop, which isn’t always the case. It doesn’t feel like a cut-down version, which is the real win.

How It Compares to Its Sister Sites

Within the family, 21 Casino is the steady middle option. Casimba beats it on sheer game count and bonus size, Playzee on promos and character, and 247Bet adds the sportsbook 21 lacks. Where 21 holds its own is the clean, no-nonsense lobby and a strong core slots line-up. If withdrawal speed matters most to you, every one of these shares the same cautious White Hat KYC, so a sister won’t magically fix that.

Pros and Cons

Pros

• Dual UKGC and MGA licensing through White Hat Gaming, with full GamStop cover, so the safety side is rock solid.
• A clean, slot-led lobby that loads fast and doesn’t bury you in banners; sign-up is quick.
• Over 2,000 games with a properly polished Evolution live dealer suite, not just a token few tables.
• Browser play on mobile that holds up well, with no clunky app to install.

Cons

• Withdrawals are slow and cautious: a 24 to 72 hour review window, and players report repeated document requests on larger wins.
• Trustpilot sentiment is poor (around 1.8 out of 5), mostly over KYC delays and patchy communication once you try to cash out.
• A thin promo calendar after the welcome, and a loyalty scheme that converts painfully slowly.
• No sportsbook, bingo or poker, and several sisters feel near-identical, so there’s little to choose between some skins.

Frequently Asked Questions

Who owns 21 Casino?

21 Casino is operated by White Hat Gaming Limited, the Malta-based platform that holds UK Gambling Commission licence 52894 and a Malta Gaming Authority licence. The brand itself sits within the Casimba Gaming family.

Which casinos are run by White Hat Gaming?

The closest are the Casimba Gaming brands: Casimba, Playzee, Casilando, Temple Nile, Dream Vegas, Grand Ivy and 247Bet. Beyond those, independent casinos like Hopa, Casiku, BetTarget, Barz and Hello Casino share the same White Hat Gaming licence.

Are 21 Casino sister sites on GamStop?

Yes. Every brand on White Hat Gaming’s UKGC licence is covered by GamStop, the national self-exclusion scheme, so a self-exclusion applies across all of them and any other UKGC site.

What is the best 21 Casino sister site?

For most players it’s Casimba, which keeps the same licensing and platform but adds a much bigger library and a chunkier welcome. If you want more personality and livelier promos, Playzee is the pick; for sports betting, 247Bet.

Is 247Bet a 21 Casino sister site?

Yes. 247Bet launched in August 2025, is operated by Casimba Gaming and runs on the same White Hat Gaming licence 52894 as 21 Casino. The main difference is that 247Bet has a full sportsbook, which 21 Casino doesn’t.

Are 21Prive and 21 Casino the same?

They’re not the same casino. 21Prive carries similar branding and sits within the wider White Hat Gaming licence family, but it’s a separate brand. The reliable way to confirm any relationship is to check the operator named in the site footer against the UKGC register.

What is 21 Casino’s welcome bonus?

The signature offer is a 121% first-deposit match up to £300, with no free spins bundled in. Under UK rules from 19 January 2026, bonus wagering is capped at 10x, so older higher figures no longer apply. Always check the live terms before opting in.

How long do withdrawals take?

E-wallet withdrawals usually clear in 0 to 2 days, while debit card and bank transfers run 1 to 5 working days. There’s a review window of roughly 24 to 72 hours first, and a first withdrawal takes longer while verification clears, so verify early.

Is 21 Casino safe and legit?

From a regulatory standpoint, yes: it holds UKGC and MGA licences, uses audited random number generators and segregated funds. That said, its Trustpilot rating is low (around 1.8 out of 5), driven mainly by slow KYC and withdrawal frustration rather than rigged games.

Our Verdict on 21 Casino

21 Casino is a safe, slot-led casino that’s let down by the thing players care about most: getting paid quickly. The licensing is sound and the games are plentiful, but the cautious KYC, slow cashouts and a rock-bottom Trustpilot score keep it out of the top tier. It suits patient slots players who verify up front and aren’t chasing promos. If you want the same regulated family with more behind it, the standout 21 Casino sister site is Casimba, a bigger library and a heftier welcome on the identical White Hat licence; 247Bet is the one to pick if you also want a sportsbook.
