Place your qualifying bets at low odds, ensuring you meet any minimum odds requirement. Use the ‘Qualifying Bet’ setting on the Matched Betting Calculator to calculate your lay stakes.
Once received, you can convert any free bets or bonuses into cash. Use the ‘Free Bet’ setting on the Matched Betting Calculator to calculate your lay stakes. It’s best to place free bets at high odds to maximise your profits.

How to lay a Bet Builder
If you’re looking to lay a football Bet Builder, you’re in luck. All you need to do is add the right combination of selections, and you’ll be able to lay your Bet Builder in one bet at the betting exchange.
Bet Builders on other sports tend not to be as straightforward, and you may struggle to lay your bet. In that instance, and depending on the offer, you may want to treat it as advantage play.
See my Bet Builders guide for a walkthrough of your options.
