No-one has won the record £166 million jackpot in Friday's EuroMillions draw.
The top prize is now frozen and will be in place for the next draw on Tuesday.
Two UK tickets did scoop £3.3 million each after matching five numbers and one lucky star.
A National Lottery spokesman said: "This is amazing - no-one won the jackpot so there is still £166 million waiting to be won next Tuesday.
"It was great that so many UK tickets banked big prizes on Friday and that is likely to be repeated on Tuesday when any prize money rolls down to the next prize level."
The winning numbers in Friday's main draw were 12, 13, 23, 40 and 49. The Lucky Star numbers were 7 and 10.
A single winner on Tuesday would be the equivalent of 418th on the Sunday Times Rich List, sitting alongside David and Victoria Beckham (£165 million) and self-made millionaire and Dragons' Den regular Theo Paphitis (£170 million).
The current biggest lottery winner in the UK is an anonymous ticketholder who scooped a £113 million prize last October.
On August 22 2009, a single ticket won Italy's SuperEnalotto jackpot, which stood at 147,807,299.08 euro (£128.3 million at the time).
