It’s Man Utd v Arsenal at Old Trafford on Wednesday and Unibet are getting in on the action! They’re giving customers a 50% profit boost to use in play on the big match! Translated into matched betting terms, this gives us a guaranteed profit of £6.04 and here’s how…

Key Terms:

  • This offer can be found behind door number 5 on Unibet’s Advent Calendar 2018 page.
  • Maximum stake of £20.00.
  • Our profit boost ticket will be available in our account by 10:00 on Wednesday 5th December 2018.
  • Our profit boost will be visible in our betslip once we have selected an eligible bet.
  • Qualifying bets must be placed in play at odds of 1.40 (2/5).

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.

Once selected in our betslip, the profit boost will boost our odds by 50%.

It’s impossible to know what odds will be available until the match has kicked off (20:00 on Wednesday 5th December 2018).

I’ll use the pre-match odds on a Draw in the following example, to illustrate how this offer should be done.

At the time of writing, the back odds are 3.55, so we need to work out what our new odds will be once the 50% profit boost has been applied…

3.55 – 1.00 (stake) = 2.55
2.55 * 1.50 (50%) = 3.825
3.825 + 1.00 (stake) = 4.825

Laying our bet at Smarkets is likely to give us the biggest guaranteed profit.

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

Place £20.00 on a draw @ 4.825 = Potential profit of £76.50

Smarkets logo

Lay £26.58 on a draw @ 3.65 = Potential liability of £70.43


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

Draw+ £76.50 – £70.43 = £6.07 profit
Not a draw- £20.00 + £26.04 (£26.58 minus 2% commission) = £6.04 profit

So, regardless of the outcome, we’ll make a guaranteed profit of £6.04 on this Unibet offer!

* Arsenal were available at back odds of 3.10 and lay odds of 3.40. The match was drawn 2-2, resulting in a profit of £4.06 on this Unibet offer. *
