The Masters 2019 Offer – MansionBet

The Masters 2019 gets underway on Thursday and you don’t want to miss this MansionBet ‘Bet £20, Get £10’ offer! Simply bet £20.00+ on the Outright Winner market and MansionBet will give us a £10.00 free bet to use in play on the golf. Translated into matched betting terms, this gives us a guaranteed profit of £4.20 and here’s how…

Key Terms:

  • We must opt-in to the promotion on the promotion page.
  • We must bet £20.00 or more on the US Masters 2019 – Winner market (pre-tournament bets only).
  • To receive our free bet, we must ‘Accept’ the promotion pop-up after qualifying bet placement.

Qualifying Bet:

If you’re unfamiliar with qualifying bets, please see my Qualifying Bet Strategy page for a walk-through guide on how it should be done.

It’s entirely up to you who you place your qualifying bet on. Having looked at the odds available, we could place our qualifying bet on Rory McIlroy.

At the time of writing, laying our bet at Smarkets gives us the smallest qualifying loss.

We can calculate our lay stake using my matched betting calculator…

As you can see, the calculator tells us that our lay stake should be £17.06…

Place £20.00 on Rory McIlroy @ 8.00 = Potential profit of £140.00

Smarkets logo

Lay £17.06 on Rory McIlroy @ 9.40 = Potential liability of £143.30


Let’s have a look at our potential profit/loss for the possible outcomes…

Outcome Bookie Exchange Profit/Loss
Rory McIlroy wins +£140.00 -£143.30 £3.30 loss
Rory McIlroy doesn’t win -£20.00 +£16.71 £3.29 loss

So, regardless of the outcome, we’ll lose a maximum of £3.30 in qualifying for our £10.00 free bet.

Free Bet:

Our £20.00 free bet will be credited upon placement of our qualifying bet and will be valid on in play golf markets, excluding the Outright Winner market. Free bets will be valid for 4 days and free bet stakes will not be included in any returns.

By using straightforward matched betting, we should be able to extract 75% cash from our £10.00 free bet, so £7.50. If we take into account our maximum qualifying loss of £3.30, this gives us a guaranteed profit of £4.20 on this MansionBet offer!

* Rory McIlroy failed to win the tournament, resulting in a profit of £4.21 on this MansionBet offer. *
