Matched betting (also known as back or lay bet matching, arb betting, or double betting) is a betting technique used by individuals to profit from the free bets and any bonus or promotions offered by bookmakers. Can be generally considered a low risk-free bet as it is based on mathematical rational than chance. The aimed return for a matched bet is normally 85%+ of the free bet offer amount (for returned stake). However, most of the free bets offered by most of the bookmakers these days are not returned which brings our margin to 65-70%+.
Matched betting is a profitable betting method by putting in opposition two different bookmakers with varying odds by betting on both teams. By using this system you can wager on an event with, theoretically, no risk of losing. The act of match betting is considered by experts to be a risk-free form of gambling if done properly.
Matched betting is a system using bookmaker incentives to bet on both outcomes of a wager. Because the bookie gives money to “bet match” as a sign-up bonus, you cover both outcomes, so you can aim for a profit. Matched betting is generally considered safe if it is done properly. It is also called lay bet matching or double betting technique.
