General advice and example for free bet offers

Once claimed, you can convert any free bets into around 80% 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.

See my Free Bets Guide for a complete walkthrough of this offer type.
