The National Lottery’s new game structure comes into effect this week, with tickets available from Thursday October 3 for Saturday’s draw.

As well as the increase in price per line from £1 to £2, changes to the Lotto game include a raffle with at least 50 winners of a guaranteed £20,000 in every draw, bigger prizes for matching three numbers and larger jackpots of £5m on Saturday and £2.5m on Wednesday.

It is expected that the new price and game structure will add to the £35m raised by the National Lottery for good causes every week.

Camelot kicks off its new game structure with two major prize draws on October 5 and 12, with 1,000 Lotto raffle winners guaranteed to win £20,000 while a £10m jackpot will be up for grabs in the main game.

To help promote the changes to customers, retailers were sent a POS pack as well as new playslips.

Camelot UK Lotteries managing director Andy Duncan paid a visit to Narendra Patel at Speedy Supermarket in Watford ahead of new Lotto going on sale this Thursday.

“It was great to visit Speedy Supermarket and see new Lotto brought to life in-store,” he said. “Narendra and his staff have done a fantastic job siting the POS and their enthusiasm is contagious. We’re delighted that retailers up and down the UK are getting behind the new game – not only driving sales in their stores but, crucially, boosting returns to the Good Causes. I would like to take this opportunity to thank every National Lottery retailer for their support – here’s to a bumper couple of weeks!”
