Changes have been announced to the EuroMillions lottery - to make even larger jackpots and create more chances to win.
The forthcoming changes see the introduction of a second draw day on Tuesdays, as well as expanding the number of Lucky Stars which should result in more rollovers and bigger jackpots.
The game's member countries - Austria, Belgium, France, Ireland, Luxembourg, Portugal, Spain, Switzerland and the UK - are also introducing a 13th prize tier, where players will win around £3 for matching just two main numbers.
The overall odds of winning a prize on the game will shorten from one in 24 to one in 13 - with the total number of prizes every week in Europe expected to more than double from 1.9 million a week to 4.6 million.
Tickets for the new-look game are due to go on sale on Saturday May 7, with the first Tuesday draw taking place on May 10.
To celebrate the launch, the first Tuesday draw will have a special "mega-jackpot" of an estimated £85 million.
Dianne Thompson, chief executive of Camelot UK Lotteries, said: "Since we launched EuroMillions in 2004, it's grown to be the world's biggest multi-national lottery game by player population.
"It has really captured the public's imagination, creating numerous multimillion-pound winners in the UK, as well as boosting returns to the Good Causes here in the process.
"These changes will make the game even more exciting for our players - with the mega-jackpot levels our EuroMillions players love, as well great chances to win smaller prizes more often."
