• You are able to win, because you use a bonus. Usually when betting your own money with the system will result in a small lost, but this way you complete the bookmakers' requirements to get the bonus, and from doing the same again with it, will result in having a profit.

• You need to understand well how back-back bets work. When betting this way, you have to make sure to place the bets on 2 outcome markets, doing the second bet on the opposite result of the first bet you made. This way, when one of the outcomes happens, you will have a winning bet and a losing bet. When you do this with the bonus on one of the bookmakers, since you're not investing your own money, you will make a profit.

This is a simplified explanation on how Matched Betting works, but to truly understand it, the best way is to complete the Welcome offer, that will allow you to win between 120$-140$.
