A bet builder is a relatively new type of bet that has emerged over the past couple of years and has been growing in popularity as more and more people find ways to make it work for them.
With a bet builder you get the opportunity to build your own bet or same game combo bet - as well as taking advantage of some pre-built bet builder selections that are generated and supplied by the bookmakers themselves.
A few years ago it was not possible to mix together bets from the same match - for example if you wanted to back Manchester City to Win and also back Over 2.5 Goals in the same game you used to have to back them as single bets.
Over the years bookmakers started to see that people wanted to do these bets more, originally they introduced pre-made combo markets such as the Win & BTTS market or the Win and Over 2.5 goals market but the people wanted more.
