The National Lottery has apologised after some issues with tickets for customers who purchased them with playslips in retail stores.
They say the issue is "a small number of cases have occurred where numbers which are manually selected have not been included on a ticket, when selected together with Quick Pick numbers."
A Lotto spokesperson said: "There have been isolated issues for some of our players in shops when using playslips to purchase Lotto, EuroMillions and Daily Million tickets with a combination of Quick Pick and Manual panels. The National Lottery apologises for any inconvenience caused.
"Specifically, a small number of cases have occurred where numbers which are manually selected have not been included on a ticket, when selected together with Quick Pick numbers. In a small number of such cases the manual selection may not have been entered into the relevant draw and customers have not been charged for that line.
"This issue may affect customers using playslips to purchase Mixed Play tickets in shops only. This does not affect online play.
"We remind all players to always check their tickets to ensure that it is correct at the time of purchase. Our technical teams continue to work to identity and rectify the issue. Players should ask shop staff, if they encounter any difficulty."
