We can calculate our lay stakes using my Matched Betting Calculator

Aim to lose no more than £1.00 on each of our 5 qualifying bets

So, we’ll lose approximately £5.00 in qualifying for each £10.00 free bet.

Free bets

Our £10.00 free bets will be credited upon settlement of our five qualifying bets and will be valid on any sports market for 7 days. Free bet stakes are not included in any returns.

Using straightforward matched betting, we should be able to convert each free bet into 80% cash, so £8.00. If we take into account our total expected qualifying loss of £5.00, this gives us a daily guaranteed profit of £3.00!

With a maximum of 5 free bets to be claimed throughout the tournament, that’s an overall guaranteed profit of £15.00 on this MansionBet offer!
