Trafiico reviews UK Gambling Commission-licensed operators for adults resident in the United Kingdom. Please confirm your age to continue.
A modern, mobile-first UK sportsbook with a full casino lobby attached. Best known for its supercharge mechanic, which at random multiplies the odds on selected sportsbook bets. The casino side leans on a broad live-dealer library rather than an in-house slot studio.
Kwiff promotes a generous welcome offer for new UK customers across its sportsbook and casino lobbies. Exact stake, wagering and eligible-market conditions change from time to time, so we direct readers to the operator's live promotion terms rather than print figures here.
The offer is opt-in at registration and the qualifying deposit must be funded from an eligible payment method. Wagering and time-limit conditions apply before any bonus funds become withdrawable. Read the full terms on kwiff.com before opting in.
Kwiff is operated by Eaton Gate Gaming Ltd, which holds a UK Gambling Commission remote operating licence under Account #44448. The brand launched as a mobile-first sportsbook and has since expanded into a full casino offering. Its signature feature is the supercharge mechanic, which can multiply the odds on selected sportsbook bets after a stake has been placed; payouts on supercharged bets are subject to the published cap.
The product is delivered chiefly through the operator's native iOS and Android apps, with full functionality also available in the browser. UK customer support runs 24 hours a day via in-app chat and email.
The sportsbook covers the standard UK markets, football, horse racing, tennis, cricket and the major North American leagues, with in-play coverage on the larger events. The casino lobby is partner-supplied rather than developed in-house, with content from Evolution and other established studios. The live-dealer suite is the strongest part of the casino offer; the slot catalogue is competent but not as deep as a slot-specialist site.
UK debit cards and Apple Pay typically settle instantly on deposit. Withdrawals are subject to identity verification under UKGC rules. Credit-card funding of gambling accounts is prohibited in the UK and is not offered.
Kwiff offers the standard UKGC-mandated account controls. We recommend configuring them before your first deposit.
