*Click on any eligible race (listed below)
*Find any horse with close back & lay odds
*Add horse to betslip, and click "boost" to boost the odds
*To work out how much you need to stake for the maximum £100 refund, do 666 / (original odds -1). We use 666 as 15% of this is £100, so we need to "win" £666 to get the full £100. You can do less, i.e. 333 for a £50 free bet and 167 for a £25 free bet.
For example, a horses odds are 5.5 boosted to 5.9. You need to do 666 / 4.5, which gives a £148 stake for the maximum £100 free bet
(You can bet up to £200 on the horse with the boost however will only receive a max £100 free bet)
*Place bet and lay at exchange

You should instantly profit from the boost if you've made the back odds higher than the lay odds

If the your horse wins by 2 or more lengths, you will receive a free bet of 15% up to £100.
