Lottery operator Camelot says UK National Lottery sales fell more than 6% in the first half of the company’s fiscal year.

This week, Camelot UK Lotteries Ltd reported sales of National Lottery tickets hitting £3.389b in the six months ending September 24, down around £226m from the same period last year. The decline meant the amount Camelot kicked back to charitable causes in its fiscal H1 fell by £92m to £783m.

The decline may have had something to do with Camelot making the National Lottery jackpot dramatically harder to win by adding 10 balls to the original 49 balls late last year. While the change led to more rollovers and thus larger jackpots, players appear to have cottoned on to the fact that the odds of winning one of those mega-prizes went from one in 14m to one in 45m.

Searching for a silver lining, Camelot heaped praise on its digital sales, which hit a record £726m in H1 2016-17. Mobile sales were up 13.5%, although this growth will likely stall in H2 due to last month’s much publicized problems with Camelot’s wonky National Lottery app.
