The draw used ball set 8 in the Lancelot machine and the average main Lotto prize was £39.53.
One in every 45.2 main Lotto tickets won a prize (=2.21% of players).
If all 13,983,816 ticket combinations were additionally purchased for the main Lotto game, they would have made a loss of £23,290,612.
The prior history of the main Lotto jackpot ticket included 42 wins totalling £488.
From Saturday 12th July 2003 onwards, Camelot has completely refused to issue per-draw sales figures for any of their individual games,
despite continuously doing so for more than 8 years prior to that date. They blamed the media for only
concentrating on the main Lotto game sales (which have been falling steadily for years), which seems to be a poor excuse to me.
However, games with variable prize tiers such as the main Lotto can have their sales figures reverse-calculated to within a few pounds, which is what I have done.
There is some dispute here about the jackpot prize pool amount. Camelot's
figure doesn't tally with their published formula and my calculations show
that it should be £1,824,512.
