Its nearest twin

Shares 2 of 5 numbers (20, 27) with the draw of 15 April 2010 — its closest relative in 30 draws. Chance gave a match this close a 95% likelihood somewhere in that history.

From the draw just before (7 May 2010): 31 carried over. Chance says 48% of draws repeat at least one number.

Sum and shape

The numbers add up to 102 — the 38th percentile of all possible tickets, around a middle of 110. No two numbers side by side. 40% of draws have at least one such pair.

The longest wait in this draw

7 had not appeared for 15 draws. A number waits about 9 on average, and a wait this long was not a signal — the machine has no memory of it.

How many people held it

A line like this is played about 2.4× as often as an average ticket — more popular than most. At 30 million tickets sold, a winner on these numbers would keep about 1% of the jackpot.
