An estimated £6.8 million is up for grabs in Saturday's Lotto game after no one won the midweek top prize.
Despite the rollover, two players have become millionaires after matching five balls and the bonus to net a welcome windfall.
Wednesday's National Lottery Lotto winning numbers were 11, 24, 25, 39, 53 and 57 and the Bonus Ball was 09.
No one scooped the £500,000 grand prize in the Thunderball draw either, but two people won £5,000 each by matching five balls.
The Thunderball winning numbers were 03, 06, 18, 23 and 30 while the Thunderball was 05.
The Lotto HotPicks competition also went without a winner, although four people scooped £13,000 prizes by matching four balls.
