MansionBet – US Open 2021 Offer

The US Open 2021 gets underway on Monday and you don’t want to miss this MansionBet free bet offer! Opt in and place five £10.00+ in play bets on the US Open each day and MansionBet will give us a £20.00 free bet. Translated into matched betting terms, this gives us a guaranteed profit of £98.00 and here’s how…

Key terms

  • We must opt in on the promotion page to be eligible.
  • Promotion runs from 15:00 on Monday 30th August 2021 until 23:59 on Sunday 12th September 2021.
  • Place 5 bets of £10.00 or more on any US Open in play markets.
  • Minimum odds of 1.80 (4/5).
  • Maximum of one (1) free bet per day.

Qualifying bets

Be aware that MansionBet have different retirement rules to Betfair and Smarkets, which could leave you exposed to a big loss in the event of a retirement. The safest way of doing this offer is dutching each qualifying bet at another bookmaker with the same retirement rules.

We can calculate our stakes using my Dutching 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.

Again, dutching is the safest way of matching our free bets and we should be able to convert each free bet into 60% cash, so £12.00. If we take into account our daily expected qualifying loss of £5.00, this gives us a guaranteed daily profit of £7.00!

With the promotion running for all 14 days of the tournament, that’s an overall guaranteed profit of £98.00 on this MansionBet offer!
