This week people in North Wales are guaranteed that their lottery ticket will not leave them empty handed, win or lose.
Ticket-holders will be able to get free access to 10 venues around North Wales.
All they need to do is show it on arrival to get free entry.
The sites that are taking part include:
Holyhead Market
Plas Newydd
Porth y Swint
Penrhyn Castle
National Slate Museum
Bodnant Garden
Yr Ysgwrn
RSPB Ynys-hir
Old College, Aberystwyth
National Trust Erddig
They are all taking part in the #ThanksToYou campaign, having all benefited from National Lottery funding since the competition launched in 1994.
More than £1.7bn has been given out since the funding scheme began.
The programme runs from today (Monday December 3) to Sunday December 9. Visitors just need to show a current National Lottery ticket to get in.
