After this free bet is placed, the other bookmakers or betting exchanges are used to hedge all other outcomes so that the value of the free bet is kept. The simplest version of a matched bet involves placing a back bet using the free bet, while also placing a lay bet for the opposite result with a betting exchange. A more sophisticated version would involve placing bets with many bookmakers at once to avoid the commission which would need to be paid for using an exchange; this practice is called dutching. Generally speaking, it’s required for bettors to place a bet using their own money before qualifying for a free bet.

If you want to continue with matched betting by taking advantage of customer reload offers, you would operate in a different way. Instead of backing and laying on the exchange in order to gain a free bet regardless of the outcome, the bettor will back with the bookmaker, lay with the exchange and hope their desired outcome will result so they can be rewarded with a free bet. The benefit of using betting calculators is that bettors can work out if the cost and reward from the free bet can justify the risk of not receiving one. There are similarities to poker seen in this strategy, as it is considered lucrative to make these low risk wagers in the long term. If the refund event takes place for a free bet, there could be hundreds made, making it hugely beneficial.

Many people will take part in two types of matched betting – assisted matched betting and manual matched betting. With assisted matched betting, there will be websites or software packages which provide the bettor with comparison tables of markets to bet on. These are referred to as auto-matchers. They are used by punters who have an understanding of what is involved in matched betting, and they will provide the punter with a matched betting calculator which can be used alongside the auto matcher. This allows the bettor to select the type of bet, stake, bonus and time frame. Manual betting involves the individual finding the offers, markets and odds for themselves. They will also make the relevant calculations. Finding the right odds and matching them can take up a lot of time, and will require both a high level of knowledge about gambling along with good numerical skills.

Although matched betting is legal, be aware that bookmakers will have people looking out for people who take on too much value. This means that they will place restrictions on the accounts of those who take advantage of promotions too often, and any bettor who repeatedly engages in such behaviour can get banned from that bookmaker site.

There are now matched betting services, which provide step by step instructions, along with software such as odds matching. The use of a betting calculator is also useful with matched betting, as the punter can enter their desired stake, along with various odds and results, to see what their potential return and profit will be.
