Best Diamond 7 Casino Sister Sites
Written by Alex MorrisUpdated 1st July 2026
Casimba
Casimba is the high-roller flagship of the White Hat family and the most obvious step up from Diamond 7. It builds everything around a bold lion theme, hands new players a large multi-part welcome package and stocks a deep Megaways and progressive-jackpot library, with quick verification and withdrawals once your account is checked.

Karamba
Karamba is one of the longest-running names on the White Hat platform, instantly recognisable by its bright orange branding. It pairs a full casino with a sportsbook, so players who like a bet alongside their slots get both under one login, and the cashier and support behave just as they do at Diamond 7. Read our full Karamba review.
Gate 777
Gate 777 wraps the White Hat engine in a stylish 1920s aviation theme. Expect a modest but fair welcome bonus, thousands of slots from the leading studios and a busy live-dealer lounge with roulette and blackjack, all laid out in a way that will feel familiar to any Diamond 7 regular. Read our full Gate 777 review.
Slot Planet
Slot Planet keeps things deliberately simple. It is a slots-first sister with a clean interface, a straightforward first-deposit match and a catalogue weighted toward video slots rather than table games. Banking runs through cards, Apple Pay and the usual e-wallets, and live chat handles most queries in minutes. Read our full Slot Planet review.
21Prive
21Prive leans into a members-club identity, with multi-currency support that suits players outside the UK as well as British ones. Beyond a solid slots library it runs a proper live-casino floor, and because it shares the White Hat back end your Diamond 7 payment methods and verification carry straight over. Read our full 21Prive review.
Spin Yoo
Spin Yoo is one of the more playful White Hat brands, built around a gamified, mission-based reward system that keeps regular play interesting. The design is modern and mobile-first, the slot range is broad, and the trusted cashier means deposits and cashouts work exactly as they do across the rest of the family.

Diamond 7 Casino Review
Diamond 7 Casino launched in 2017 and has kept a polished, jewel-themed look ever since. It runs on the White Hat Gaming platform, so the game library spans video slots, jackpots, scratch cards and a live-dealer section powered by the major studios. New UK players are welcomed with a 100% match up to £100 plus 25 free spins on selected slots, and a tiered loyalty scheme rewards regular play with points and reloads.
Because it sits on the same licence and cashier as its sisters, banking covers debit cards, Apple Pay and the main e-wallets, withdrawals are processed quickly once identity checks clear, and support is available through live chat and email. It holds both the UK Gambling Commission licence (52894) and a Malta Gaming Authority licence, so UK players get full GamStop and deposit-limit protections.
