Related selections change the model
A team winning and the same team scoring several goals can share information. A striker's goals and the team's victory can also be dependent. Treating these legs as independent can misstate the joint probability. The builder can reject certain combinations or offer a combined price reflecting its own assessment.
Suppose two standalone selections each show decimal 2.00. Their product is 4.00, but a builder might quote 3.00 because the events are positively related under its pricing model. The accepted combined quote, not an assumed multiplication, controls an ordinary winning payout. A ₹100 win at 3.00 returns ₹300 including the stake.
What must happen for a win?
A standard builder commonly requires every active selection to qualify. One failed selection can lose the whole combined stake. Player non-participation, void legs and interrupted events can have special treatment, including recalculation or cancellation. The exact builder rules must be read rather than importing an ordinary accumulator convention.
Boosts and promotions
A promotional boost can affect profit or the quoted price under a separate formula. Minimum leg counts and exclusions can matter after a void. A higher displayed potential return does not establish improved true probability or positive expected value.
Keep the accepted configuration
Record each leg, event period, line, participation condition and final combined price. A later standalone price change does not automatically change the accepted builder. To explain settlement, check each leg against its rule and the authorised result before calculating the final return. The product adds combined coverage conditions, not a guarantee of success.
Can the same legs be priced differently after one event occurs?
Yes. Live information can change the conditional relationship and quote, or the builder may stop offering the combination. The original accepted receipt still defines its own contract under the rules. Do not compare a pre-event combined price with an in-play quote as though the information is identical. A standalone outcome already occurring can also change what new combinations are available. The builder's accepted legs, period and price are more useful settlement evidence than a later promotional preview.
