The €2,773,649 jackpot winning ticket in last night's Lotto was sold in Co Carlow.
National Lottery bosses are appealing for punters to check their tickets after a bumper night on Saturday.
Two more players fell just one number short of the top prize after matching five numbers and the bonus ball.
These tickets were sold in Co Cork and Co Tipperary, and the lucky players will share the €141,450 prize.
The €70,725 winning tickets were sold at JJ Field’s store on Main Street in Skibbereen, Co Cork and at the Applegreen service station on the Dungarvan Road in Clonmel, Co Tipperary.
Last night's all-important winning Lotto numbers are: 14, 20, 24, 38, 41, 45 and the bonus was 3.
Lotto chiefs said they expect to reveal the store where the winning ticket was sold next week.
A spokeswoman said: "Last night’s Lotto draws produced a massive 92,000 winners including these three huge winners in Carlow, Cork and Tipperary.
