Frequently asked questions
What is a bookmaker margin?
It is the built-in profit of the bookmaker. If the implied probabilities of all outcomes add up to more than 100 percent, the extra is the margin.
How do I read American odds?
Plus 150 means a stake of 100 wins 150 profit. Minus 200 means you must stake 200 to win 100 profit.
