Because they love multis so much, bookies regularly offer promos and bonus bets on them. A smart matched bettor can use these to turn the odds in his or her favour. Whether it is a ‘refund if one leg loses’ offer or an odds boost, by using matched betting strategies it is possible to give yourself a risk-free shot at a profit, or even to lock-in a guaranteed return.

However, the maths behind these strategies can be tricky at times. That is why we have created our unique Multi Promo Calculator.

If a user enters their multi odds, and details of any promo, the calculator will work out the lay stakes that they need.
Depending on the method selected, the lays will either return a break-even result if any leg loses, with a big profit if they all win, or they will return an equal profit no matter what happens in the last leg.
The Multi Promo Calculator is just one of the many matched betting calculators available to Bonusbank members. By using it, along with our other features, you can make money from the bookies week after week.
