Matched betting is the act of taking advantage of bookmaker offers to make a guaranteed risk-free return. This is done by placing bets on a bookmaker and an exchange site to trigger free bet promotions and using these bets to tie up a guaranteed profit. Because of the free bets, you can make nearly twice your stake with each matched bet.

Matched betting (also known as back bet matching, lay bet matching, or double betting) is a betting technique employed by individuals to profit from free bets and incentives offered by bookmakers. Its proponents considered it risk-free in theory-based probability.

Matched betting is a betting strategy that allows you to make money from the promotions offered by bookies. These are usually free bets or deposit bonuses. Instead of betting on who you think will win, you cover all potential outcomes of an event, so that you make profit no matter what.

Matched betting is a technique that mathematically generates a profit from free bet promotions offered by betting companies. Almost all bookmakers advertise these offers to entice new customers to place bets with them. For example, "bet £25 with us and we'll give you a £25 free bet!".

Matched betting is a form of gambling which can greatly increase your chances of winning, while in turn decreasing your chances of a loss from your bets. When placing a matched bet, you cover all options for the outcome of the bet and have the opportunity to either break even or make profit from whichever selection is the winner.
