A Bet Builder combines several selections from the same event into one bet.
The difference from a Parlay is that a Parlay combines different events, while a Bet Builder combines markets within one event.
For example, in one football match: Team A to win + Over 2.5 goals + Player X to score.
It works like a Parlay. All selections must be correct for the Bet Builder to win, and if any selection loses, the whole bet is lost.
Bet Builder is only available for events marked with the Bet Builder tab. Not every sport, event or market offers it.
Bet Builder odds are calculated for the whole combination, not by simply multiplying the odds of each selection. Selections from the same match are often connected (for example, a team winning and that team's striker scoring), so the combined odds are usually lower than simple multiplication would give.
A Bet Builder can be added to a Parlay or System bet, together with other Bet Builder bets or regular selections.
Bet Builder availability can change.
