Qualifying bet
- Check the back odds at Kwiff and the lay odds at Smarkets to find a suitable selection. Your qualifying bet must be placed at minimum odds of 1.50 (1/2).
- Use the ‘Qualifying Bet‘ setting on the Matched Betting Calculator to calculate your lay stake.
- Place your £10 qualifying back bet at Kwiff. There’s a chance your odds will be ‘Kwiffed’, a fancy way of saying ‘boosted’. If that happens, use your Kwiffed/boosted odds as your back odds when using the calculator.
- Place your lay bet against the same selection at Smarkets.
Surprise bet
- Within 48 hours of placing your qualifying bet, Kwiff will place a £30 Surprise Bet for you. You’ll be able to see your Surprise Bet in the ‘My Bets‘ section of your account. Hopefully, it will have been placed on a selection you can lay at Smarkets. If not, you must let it run and hope it wins.
If your Surprise Bet is on a tennis market, be aware that Kwiff have different retirement rules to Smarkets, which could expose you to a loss in the event of a player retiring. A safe alternative is dutching your qualifying bet at another bookmaker with the same retirement rules.
- If you can lay your Surprise Bet, check the odds at Smarkets.
- Use the ‘Free Bet‘ setting on the Matched Betting Calculator to calculate your lay stake.
- Place your lay bet against the same selection as your Surprise Bet at Smarkets.
As a rough guide, limit your qualifying loss to around £1. Most Surprise Bets are layable, and the cash profits tend to range between £12 and £18, depending on the selection and the odds. Based on an average cash profit of £15, you should make a £14 profit on this Kwiff offer.
