@@OtakuLogan2017 I know it now. It was Big Draw in 1999 and 2000 to celebrate the new year, and it was Christmas Millionaire Maker from 2001 to 2003 to celebrate Christmas.
They could do it again. I think to fix it, they would make it £3 per ticket instead of £5; the Jackpot in game 1 climbs up from a minimum of £10,000,000 based on the sales rather than staying at a certain amount, players can choose as to whether or not they want to play Christmas Millionaire Maker or Big Draw or both, tickets go on sale at the start of November rather than December to help build the Jackpot better.
