Camelot has announced record National Lottery sales of £7.3 billion - an increase of more than £500 million on a year earlier.
The improvement in the year to March 31 follows the relaunch of the flagship Lotto game in October 2013, with £2 tickets and increases in the prize pool and the minimum win contributing to higher sales for the second year in a row.
Lottery operator Camelot said the amount generated for good causes also rose to £1.8 billion, taking the total delivered to date to more than £33 billion.
The National Lottery has so far given away some £55 billion in prizes and created more than 3,800 millionaires or multi-millionaires since its launch in 1994.
Andy Duncan, chief executive of Camelot UK Lotteries, said: "The National Lottery is all about changing lives - for the hundreds of thousands of beneficiaries of lottery funding and for all of the winners we create.
"Having raised almost £1.8 billion for National Lottery projects and awarded over £4 billion in prize money to our players during the year, we're delivering on that promise.
Total prize money awarded in 2014/15 was £4 billion, up £406 million on 2013/14.
