⚡ About Kwiff
Eaton Gate Gaming Ltd, UKGC licence #44448
Kwiff is the consumer brand of Eaton Gate Gaming Ltd, a UK-domiciled operator licensed by the Gambling Commission. The product launched in 2015 with a focus on mobile-first sportsbook betting and has expanded into casino, live casino and virtual sports. Its signature feature is the supercharge: certain bet slips are randomly enhanced before settlement, increasing the potential return on a winning bet without changing the stake.
Editorially, Kwiff sits in a small group of UK sportsbooks built around a distinctive interaction model rather than scale. The brand is recognisably UK in tone, with Premier League and racing coverage at the centre of its sportsbook.
🕹️ Sports & casino
Sportsbook depth with a well-integrated casino
Sportsbook breadth is the headline: football across major and minor European leagues, horse racing with daily UK and Irish meetings, tennis, rugby and a competent in-play offering. The casino sits alongside under the same account: slot catalogue from established suppliers, a live-casino lobby with roulette, blackjack and game-show titles, and a small classic-tables section.
The mobile experience is the strongest part of the product. Browser play is fluid, and the supercharge animation surfaces cleanly without dominating the bet slip.
💳 Payments
UK-friendly methods with same-account withdrawals
- Visa / Mastercard debit cards
- Apple Pay
- PayPal

Credit cards are not accepted for gambling in line with UKGC rules. Withdrawals are returned to the original deposit method where possible. KYC checks are routine and typically resolved within the operator's published service window.
