If you have a non-runner in a Lucky 15 is that your bet will still go ahead with the other three selections.
When placing Lucky 15s and one of your selections is a non-runner the bet will stand on any remaining selections. This means any single bets on non-runners will be void. The Double bets that contain a non-runner will become Singles, Treble bets become Doubles and the Accumulator will now be a Treble.
The lucky fifteen bets will still stand and go ahead but it will be calculated removing the non-runner, obviously, the number of multiple bets will also be decreased, a rule 4 won’t necessarily be applied.
