kwiff is one of the original mobile-first sportsbook and casino brands. Launched back in 2015, it pioneered the ‘Supercharged’ betting feature, where any bet a player makes has a chance of having its odds increased after it has been placed. kwiff’s focus on creating a slick mobile betting experience has set it apart from competitors, particularly in its core UK market. kwiff partnered with St8 in April 2026, in a deal that gave the operator access to St8’s content aggregation, promotional tools, and real-time reporting via a single integration.
kwiff’s sportsbook covers major sports including football, horse racing, rugby, boxing, golf, darts, snooker and more. Its core point of difference is Supercharged betting: singles, multiples, pre-match and in-play bets can all receive an odds boost after the bet is accepted, although this does not apply to casino wagers. The app also supports Bet Builder, accumulators, multi bets, live betting and regular sports promotions.
While kwiff is best known for sports betting, it also offers a full online casino, including slots, table games, and live casino content. Among the major suppliers are Evolution, Playtech,Pragmatic Play, Ezugi, NetEnt, Play’n GO, Blueprint Gaming and Hacksaw Gaming. kwiff’s integration with the St8 platform will further expand these options to include regular new content from the hottest studios worldwide.
kwiff’s promotions are built around the same surprise-led mechanic as its core product. New and existing customers can receive sports offers, casino promotions, free bets, free spins, accumulator boosts and Surprise Bets. Most kwiff promotions have low wagering requirements, making them more accessible to casual punters. To support its brand, kwiff is also the Official Betting Partner of several major football clubs, including Millwall, Leicester City, Swansea City and Motherwell.
kwiff is licensed and regulated by the UK Gambling Commission, the Malta Gaming Authority, and the Irish Revenue Office. Responsible gambling tools include deposit limits, loss limits, reality checks, time-outs, product restrictions, GamStop and self-exclusion, with self-exclusion periods ranging from six months to five years.
