Bet Builder
Due to their recent popularity, you may be asking what is a Bet Builder? In essence, a Bet Builder allows you to combine a number of selections (usually called legs) from the same game into a single bet. This can be in the form of a double or an accumulator. For the bet to pay out, each individual selection must win. This makes it less likely, but the odds are greatly improved.

The Theory: How it Works
A Bet Builder is like an accumulator, but all of the legs are from the same event. These legs are combined and the odds multiplied. It can be doubles, but more often they have three or more legs. The main advantage is they enable punters to create personalised bets.
The odds behind this Builders tool can get complicated quickly, so many of the top betting sites offer tips and calculators. Many bookmakers also offer it with enhanced odds.
Bet Builders are particularly popular in football, but have spread to other team sports too. Some selections that can be included in a Bet Builder include match result, both teams to score, Over/Under, goal scorer markets, cards and corners.
3 Examples of the Bet Builder
Here are some basic examples:
1st Example
Soccer – Liverpool vs. Aston Villa:
- Liverpool to Win @ 1.60
- Mohamed Salah to Score Anytime @ 2.40
- Under 2.5 Total Goals @ 2.50
Total Odds: 9.60
If you placed a €5 bet on this Bet Builder, your return would be €48 for a €43 profit.
If you had placed these three bets independently, you would have:
€8 + €12 + €12.50 so a return of €32.50 for a €15 stake (i.e. a profit of €17.50).
2nd Example
NFL – Super Bowl LIX:
- Kansas City Chiefs to Win
- Patrick Mahomes 275+ Passing Yards
- Patrick Mahomes 2+ TD Passes
3rd Example
NBA – Golden State Warriors vs Houston Rockets:
- Golden State Warriors to Win
- Stephen Curry 25+ Points
- Jimmy Butler 5+ Assists
