Three giant Lotto balls have been placed in Cardiff Bay, to mark big changes to the National Lottery which see tickets now cost £2 instead of £1.
Organisers Camelot say the balls are the biggest ever created - at twice the height of a double-decker Cardiff bus.
The new Lotto launch celebrations were held at the Wales Millennium Centre, built with the aid of lottery money.
Tickets for the new game went on sale today, with the first draw taking place this Saturday.
Organisers Camelot say their revamp - the biggest since the National Lottery began in 1994 - will give players more ways to win more money.
