I think in this case the winnings were fixed and the surge in sales in Rolldown days would cause the pot to be drawn down much more, meaning a longer delay before the next Rolldown day. So Rolldowns probably became less frequent, but otherwise the lottery made their money and everyone took home exactly the winnings they would have in that particular game.
