21Prive Sister Sites and the White Hat Gaming Network Explained

21Prive’s sister sites are the other casinos run by White Hat Gaming Limited, including 21 Casino, Casimba, Dream Vegas, Hello Casino, Gate 777, Spinland and Karamba. They share the same operator, the same White Hat Gaming platform and game library, and the same UK Gambling Commission and Malta licences. What sets 21Prive apart is its premium, glitzy styling and a large multi-provider catalogue, set against a fairly modest welcome offer.

21Prive Sister Sites in Full

A quick note on the term. White Hat Gaming powers a big roster of casino brands, some it owns and some it runs white-label for partners. “Sister sites” here means the other casinos on the same White Hat Gaming operator licence and platform, which is the common UK search meaning, not a small official 21Prive family. One thing to know: White Hat keeps balances brand-specific, so a balance at 21Prive does not follow you to a sister.

Best 21Prive Sister Sites at a Glance

• Best overall: Casimba, the polished White Hat flagship with a big welcome package.
• Best near-twin: 21 Casino, the obvious match and slots-led like 21Prive.
• Best for glitz: Dream Vegas, sleek and slots-heavy.
• Best simple welcome: Hello Casino, a tidy 100 percent matched deposit.
• Best themed pick: Gate 777, an aviation-styled casino.
• Best for variety: Karamba, a long-running, well-known brand.

21Prive Sister Sites Compared

Casimba

Casimba is the polished White Hat flagship and the brand to look at first if 21Prive’s modest welcome leaves you wanting more. UKGC and MGA licensed, with a large multi-provider library and one of the more generous matched welcome packages in the group. Versus 21Prive, it is the bigger-bonus, higher-profile option on the same platform.

21 Casino

It is not just the shared “21” in the name, 21 Casino is the obvious near-twin to 21Prive, leaning into slots with a few thousand titles and a welcome match that often runs a bit larger. UKGC-licensed White Hat. Versus 21Prive, very similar in feel, usually with the edge on bonus size.

Dream Vegas

Dream Vegas brings sleek, glitzy styling and a slots-heavy library, with a welcome match plus a chunk of bonus spins. UKGC and MGA licensed on the White Hat platform. Versus 21Prive, expect more bonus spins and a similarly premium look drawing on the same catalogue.

Hello Casino

Hello Casino keeps it simple with a clean 100 percent matched deposit up to a hundred pounds and a hundred spins. Plainer than 21Prive to look at, but with the same games and the White Hat loyalty scheme. Versus 21Prive, it is the straightforward, no-frills sister with a comparable offer.

Gate 777

Gate 777 wraps the White Hat platform in a 1920s aviation theme, which gives it more character than most sisters. UKGC-licensed, same shared library. Versus 21Prive, it is a themed change of scene rather than a different casino underneath.

Karamba

Karamba is one of the better-known names in the White Hat stable, a long-running all-rounder with slots, live casino and sport in some markets. UKGC and MGA licensed. Versus 21Prive, it is the bigger brand with broader recognition, on the same engine and licence.

The Complete White Hat Gaming Sister Sites List

White Hat Gaming runs one of the largest UK casino networks under a single operator licence, so the family is wide.

Headline brands include: 21Prive, 21 Casino, Casimba, Dream Vegas, Hello Casino, Gate 777, Karamba, Spinland, Casilando, Jackpot Village, Playzee, Grand Ivy, Skol Casino, Diamond 7, Slotnite and G’Day Casino.

Where the licence sits: White Hat Gaming Limited is the named operator, UK Gambling Commission account 52894, registered at the Cornerstone Business Centre, Mosta, Malta, and also licensed by the Malta Gaming Authority. You can verify any two brands are related by checking the operator name and account number in the footer against the UK Gambling Commission register.

One honest caveat: White Hat’s roster changes as brands launch and retire, so older affiliate lists name sites that have closed. Any list is a snapshot, so check a site is live before joining. Remember too that White Hat keeps balances brand-specific, so each sister is a separate account and a separate welcome offer.

What’s the Same and What’s Different

Are These Official 21Prive Sister Sites?

Three groups get conflated. There is no small “official 21Prive family”, because 21Prive is one brand in a large network. The same-operator network, which is what UK searchers usually mean and what we cover, is the wider White Hat Gaming roster led by Casimba and 21 Casino. And there are unrelated casinos that simply share game studios; using the same NetEnt or Evolution games does not make two brands sisters. We have kept to verified White Hat Gaming brands.

21Prive Review

21Prive is one of the more premium-feeling casinos in the White Hat Gaming stable, all glitz and glamour in its styling, with a deep multi-provider game library behind it. It is run by White Hat Gaming Limited and holds both UK Gambling Commission and Malta licences, so UK players get GamStop cover and proper dispute resolution. It has been around since 2018 and is still going, with its terms last refreshed in early 2026. The honest read is that 21Prive is a good, safe casino whose welcome offer is on the modest side next to bigger White Hat sisters like Casimba.

Welcome offer and promotions

The UK welcome is a 100 percent matched deposit up to a hundred pounds plus a hundred bonus spins on Gonzo’s Quest or Starburst, a tidy if unspectacular start. Under the UK rules in force from 19 January 2026, bonus wagering at UK-licensed casinos is capped at 10x and mixed-product bonuses are banned, so the live UK terms sit within that cap. If you see an old 35x or 40x figure quoted on affiliate pages, that is stale or non-UK; check the current terms on site, which must meet the 10x ceiling. There is also a small VIP club and the occasional weekend reload.

Games and providers

This is 21Prive’s strongest suit. The lobby pulls from more than a hundred providers, NetEnt, Microgaming, Evolution, Pragmatic Play and many more, so there are thousands of slots, a full table-game set and a solid live casino with game shows like Crazy Time and Mega Ball. You can favourite games and filter by provider, which makes the big catalogue easy to navigate.

Payments and withdrawals

21Prive takes cards and the usual e-wallets, with a ten pound minimum withdrawal. Cashouts run through a 24 to 48 hour pending period, after which e-wallets are quick and cards and bank transfers take a few days, which is standard for the White Hat platform. Player reports are broadly positive on payouts, with the main grumbles being a weekly withdrawal cap and Skrill or Neteller deposits being excluded from the welcome bonus.

Support and responsible gambling

Support is available 24/7 through live chat and email, in several languages. As a UKGC-licensed site, 21Prive is covered by GamStop and offers deposit limits, time-outs and reality checks. GamCare and BeGambleAware are the UK support services if play stops being fun. The site applies affordability checks, in line with current UK expectations.

Mobile

There is no dedicated app, but the White Hat platform is fully mobile-optimised, so the whole casino, lobby, banking and live games, runs cleanly in a phone browser.

How it compares to its sister sites

Against its sisters, 21Prive holds its own on game range and presentation but trails on welcome size. Casimba and 21 Casino run bigger packages on the same platform, while Dream Vegas offers more bonus spins. The games, licence and safety are shared, so the choice often comes down to the welcome offer and the theme you prefer.

Our Verdict on 21Prive

21Prive is a solid, well-licensed White Hat casino with a premium feel and an excellent game range, held back mainly by a modest welcome and light ongoing promotions. Of the 21Prive sister sites, Casimba is the pick if you want a bigger welcome package on the same trusted platform, while 21 Casino is the closest like-for-like and often edges it on bonus size. 21Prive suits players who value game variety and a polished, safe environment over a headline bonus. Bonus hunters should compare the sisters’ offers first, since the casino underneath is much the same.
