Camelot said that no ticket matched last week's jackpot numbers - 2, 5, 21, 22, 25, 32.
But seven people who matched five numbers and the bonus ball - 46 - are expected to win £368,000 each.
A lottery spokesman, David Rigg, said this week's top prize could reach £17m - close to the £17.8m that was scooped by one winner in the first lottery rollover in December.
Camelot can offer occasional Super Draws as part of an agreement with the regulator, the Office of the National Lottery. And early figures suggest that last week's "top-up", from specially-held reserves, proved a temptation for many punters.
Other results from Saturday night's draw: There were 601 winners of the Match 5 draw, winning £2,678 each; 46,339 winners of the Match 4 draw, winning £76 each; 978,819 winners of the Match 3 draw, winning £10 each. Total sales amounted to £57,529,347.Reuse content
