Place £10.00 on San Francisco 49ers @ 3.15 = Potential profit of £21.50

Lay £9.32 on San Francisco 49ers @ 3.40 = Potential liability of £22.36


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

Outcome Bookie Exchange Profit/Loss
San Francisco 49ers win +£21.50 -£22.36 £0.86 loss
San Francisco 49ers don’t win -£10.00 +£9.13 £0.87 loss

So, regardless of the outcome, we’ll lose a maximum of £0.87 in qualifying for our free bet.

Free Bet:

Our £5.00 free bet will be credited upon placement of our qualifying bet and will be valid on any in play NFL market. Free bet stakes are not included in any returns.

Using straightforward matched betting, we should be able to convert our £5.00 free bet into 75% cash, so £3.75. If we take into account our maximum qualifying loss of £0.87, this gives us a guaranteed profit of £2.88 on this Unibet offer!

* Green Bay Packers won the match 34-17, resulting in a profit of £2.88 on this Unibet offer. *
