The World Darts Championship 2019 gets underway in December and you don’t want to miss this ‘Bet £10, Get £10’ offer from William Hill! Simply bet £10.00 on the Tournament Winner market and William Hill will give us a £10.00 free bet to use on the darts. Translated into matched betting terms, this gives us a guaranteed profit of £6.31 and here’s how…

World Darts Championship 2018 Offer - William Hill

Key Terms:

  • We must place a £10.00 win or £5.00 each way bet on the Tournament Winner market.
  • Qualifying bets must be placed between 17:00 on Monday 26th November 2018 and the start of the first match on Thursday 13th December 2018.

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.

Having looked at the odds available, we could place our qualifying bet on Gary Anderson.

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

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

Place £10.00 on Gary Anderson @ 4.333 = Potential profit of £33.33

Betfair logo

Lay £8.75 on Gary Anderson @ 5.00 = Potential liability of £35.00

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

Outcome Bookie Exchange Profit/Loss
Gary Anderson wins +£33.33 -£35.00 £1.67 loss
Gary Anderson doesn't win -£10.00 +£8.31 £1.69 loss

So, regardless of the outcome, we’ll lose a maximum of £1.69 in qualifying for our £10.00 free bet.

Free Bet:

Our £10.00 free bet will be credited by 21:00 on Thursday 13th December 2018 and will be valid for 4 days. Free bet stakes will not be included in any returns.

By using straightforward matched betting, we should be able to extract 80% cash from our £10.00 free bet, so £8.00. If we take into account our maximum qualifying loss of £1.69, this gives us a guaranteed profit of £6.31 on this William Hill offer!
