Switch the odds on Mansion Bet to decimal format.

To help you find the best Qualifying Bet, and to find it quickly, we recommend to use your Oddsmonkey Oddsmatcher tool. Remember to filter the odds to between 2.0 and 2.80.

If you haven’t tried the Oddsmatcher yet you can try it here for just £1.

ii) Select a Qualifying Bet and check the odds at MansionBet and Smarkets

Remember on Smarkets: #BLUE BOXES.

Choose a bet from the Oddsmatcher then check the odds are as expected at MansionBet and Smarkets. (If not hit ‘Refresh’ on the Oddsmatcher to update the list of available bets). 

STEP 2: Calculate the Lay Bet Amount

Using the Qualifying Bet Calculator

You will now need to enter:

  1. Your stake amount at the bookmaker (minimum £10, but we will use £20 in this example as we want to look like a good customer from the start)
  2. Your back odds at the bookmaker (must be minimum of 2.0)
  3. The blue box lay odds from Smarkets

The calculator then works out your lay stake amount, which you will use for your against bet at Smarkets.


> Check your Smarkets balance is greater than your calculator liability.

> Reduce the chance of partially-matched bets or un-matched bets by making sure the liquidity (amount under blue lay box) is larger than your lay stake amount.

STEP 3: Placing your bets
