Lotto $30 million megadraw to be drawn on Saturday

Up to a third of Australian adults are expected to purchase a ticket into Lotto's $30 million megadraw, officials say.

On Saturday, the day of the draw, more than 3000 Lotto tickets a minute are expected to be sold at peak times.

Lott spokesperson Matt Hart said while Lotto is a game of chance and every number has an equal chance of being drawn, officials can reveal the most frequently and least frequently drawn Lotto numbers during the past 38 years.

The most frequently drawn, or 'hot', numbers during this time were 1, 11, 8 and 7.

Meanwhile, the least frequently drawn, or 'cold' numbers were 44, 14, 30 and 27.

"Will Lotto's 'hot' and 'cold' numbers live up to their reputation this weekend, and where in Australia will those division one wins land? Only time will tell," spokesperson Matt Hart said.
