National Lottery billion-pound jackpot

The new game format is part of a broader effort by operator Allwyn to modernize the lottery and attract a younger generation of players.

Tickets for the shared jackpot game will cost £4 per line, offering two chances to win with every entry.

The move follows a historic agreement with the Multi-State Lottery Association in the U.S. and is expected to double the number of millionaires created across the UK. The first draw for the new billion-pound prize is scheduled to take place this summer.
