Kwiff New Customer Offer: Bet £10, Get £40 in Free Bets

Kwiff is a sportsbook that built its name on super-kwiffed odds, where selections are randomly boosted before you confirm your bet. The new customer offer is simpler: sign up, deposit, and place a qualifying bet of at least £10 at minimum odds of 2.0. Once your bet settles, you receive £40 in free bets, credited as one £10 single, two £10 accumulators (minimum three selections each), and one £10 bet builder (minimum three selections). The free bets need to be used within seven days, and winnings from free bets are paid in cash with the stake not returned. See Kwiff's website for full terms and conditions.

Arsenal's Champions League run has been one of the stories of the season, and they face a serious test in the semi-finals when they travel to Atletico Madrid's Wanda Metropolitano for the first leg on 29 April. Atletico at home in a one-off knockout tie is never straightforward, and the second leg at the Emirates on 5 May should make for a fine occasion regardless of the first-leg result. Both matches offer the kind of deep markets that suit the matched betting approach well.

The qualifying bet is a straightforward single. Use OddsMatcher to find a market where the back odds on Kwiff sit close to the lay odds on Betfair, keeping the qualifying loss as low as possible at odds around or just above 2.0. Place your £10 back bet on Kwiff and lay the same selection on Betfair Exchange to cover your liability. Once the free bets land, put the singles and accumulator tokens on higher-odds selections, again laying them off on Betfair. Free bets are stake-not-returned, so aim for lay odds that give you around 70 to 75 per cent of the face value as guaranteed profit. The bet builder token works the same way by laying an equivalent combined selection on Betfair.

Lay, back and profit!
