How does Best Odds Guaranteed work when placing your bets?

Take a price on a horse and if it shortens or goes out you are guaranteed the best price.

Example 1 of a Horse Racing bet placed with Best Odds Guaranteed:

  • Place a 4/1 horse racing bet with best odds guaranteed at the bookmaker of your choice on this page.
  • The horse wins and returns an SP (starting price) of 3/1.
  • You will get paid out at 4/1.
  • If the same bet drifted in odds and won at an SP of 6/1 you would get paid out at 6/1.

It's basically a no lose situation. You cannot lose out by taking the early price. This is because:

Example 2 BOG (Best Odds Guaranteed)

If you took the 4/1 on your horse racing bet and it won at 9/2 you get the 9/2.
If you took the 7/2 and the horse racing bet won at 7/4 you get paid out at 7/2.

All the above online bookies come recommended by and are mentioned throughout this site. You can claim £100's of pounds in free bets when you choose to sign up to them and place your first bets.
