Tickets for a Euro Lottery will go on sale this weekend, offering jackpots which could reach £50m or more.
National Lottery enthusiasts will have another outlet
The game is described by Camelot as its "most ambitious game since the launch of the National Lottery" 10 years ago.
Tickets will cost £1.50 in the UK and offer a greater range of prizes than existing games.
The new game, called EuroMillions, is being run in conjunction with lottery operators in France and Spain and more countries could join next year.
Tickets will go on sale on Saturday and the draw will take place every Friday evening, starting on February 13.
The draw will be shown on Sky Television - the first time a National Lottery draw has been transmitted by a commercial broadcaster rather than the BBC.
The starting jackpot is estimated at £10m and Camelot says the average is likely to be around £14m, though rollovers mean it could grow to £50m or more.
Sales of lottery tickets have stabilised after several years of decline and Camelot hopes EuroMillions will help sales grow again.
