The second largest EuroMillions jackpot - £126 million - is up for grabs tonight.
A double-rollover means the largest pot since Colin and Chris Weir, from Largs in North Ayrshire, won £161 million last July, is on the table.
Last Friday six people won £266,505.80 each after matching five main numbers and one lucky star, but no-one matched all seven to claim the £106 million jackpot.
Tonight's estimated jackpot would propel a ticket-holder above a winner who banked £113,019,926 in October 2010, but decided not to go public.
Dave Dawes and wife Angela, from Wisbech, Cambridgeshire, currently sit third in the list after claiming £101,203,600 last October.
