What is a Bet Builder (Same Game Parlay)?
Definition: A bet builder, called a same game parlay (SGP) in the US, is a feature that lets players combine several selections from one event into a single bet.
Example: in one football match, a player combines home win + over 2.5 goals + a named player to score.
How it differs from a regular accumulator:
- A regular accumulator combines selections from different events.
- In a bet builder, selections from the same event are related, e.g. a home win and the home striker scoring.
- The price is calculated by a correlation model. Simply multiplying the odds would misprice the bet.
Platform requirements: a pricing engine for related selections, clear rules for void selections and fast price updates during live play.
