A Tatts group spokesperson told me, the amount estimated to have been spent by hopeful players couldn't be revealed, because it's an ASX listed company and the information is share price sensitive.
But what we do know, are the odds of winning such a prize.
Because no one picked the winning seven numbers, the division one pool surges to $70million next week, still below the all-time record of $106.5million won by two players in June 2009.
If you play one game, the odds of winning the Oz Lotto jackpot is one in 45,379,620.
That's double Australia's population.
Odds based on 18 games is 2,521,090 to one.
It's still way off the world's largest lottery jackpot of US$656million.
That's $634million if you convert it at today's rate.
The Mega Millions winning numbers were selected by three players across three states in the US back in March, which means the money was split three ways.
And the chances of winning the Mega Millions?
US lottery officials say, one in 176,000,000.
You're more likely to be struck by lightning.
The US National Lightning Safety Institute puts those chances at one in 280,000.
