What is a SureBet?


As odds of different bookmakers are different for a same event, there are cases where you can make a sure profit whatever the outcome of this event.
For that, you have to analyse, at the same time, all bookmakers' odds and calculate the « scenarios » where you are a 100% winner whatever the final result.
Collecting all the possible results for a specific match and verifying the following formula :
1/ Odds 1 + 1/ Odds 2 + ... + 1/ Odds n < 1

For example:
You decide to bet 100 pounds on the victory of Manchester against Barcelona.
The odds are the following :
Manchester Draw Barcelona
Williamhill 1.9 3.5 3.9
Betfair 1.3 3.7 6.2
1/1.9 + 1/3.7 + 1/6.2 = 0.9732 < 1

Here we show you how to determine how much you are going to bet for every forecast using your 100 pounds capital :
* Victory of Manchester at Williamhill > 100 £ * 1/1.9 = 52.63£
* Draw at Betfair > 100£ * 1/3.7 = 27.03 £
* Victory of Barcelona at Betfair = 100£ * 1/6.2 = 16.13£

In the case of the victory of Manchester :
At Williamhill, you win 52.63£ * 1.9 = 99.99 pounds
You lose at Betfair 27.03 *+ 16.13 = -43.16
Your total earnings are then 56.83 £.

In the case of draw
At Betfair, you win 27.03 * 3.7 = 100.01£
At Betfair you lose 16.13£ + 52.63£ at Williamhill = 68.76£
Your total earnings are then 31.25£.

In the case of a victory of Barcelona:
At Betfair, you win 16.13 * 6.2 = 100.01£
At Betfair, you lose 27.03£ +52.63£ at Williamhill = 79.66£
Your total earnings are then 20.35£.

You will make a minimum sure profit of 20,35 pounds.
