One ticket holder scooped a jackpot of £11.7million on Wednesday's Lottery, organiser Camelot said.
The winning Lotto numbers were 01, 02, 03, 04, 20 and 21, and the bonus number was 22.
Set of balls three and draw machine Arthur were used.
One player matched all six numbers to take home £11,749,355, while 14 ticketholders each won £3,848 after matching five balls and the bonus.
It meant the jackpot winner received more than 3,000 times the prize money of a runner-up, despite matching only one extra main ball instead of the bonus.
A total of 187 people matched five numbers to win £303, while 9,657 received £37 for four balls, and 134,881 won £25 for three balls.
No-one won the top prize of £350,000 in the Lotto HotPicks draw.
The winning Thunderball numbers were 03, 04, 21, 31 and 38 and the Thunderball number was 11.
No one scooped the top prize of £500,000.
