Its nearest twin

Shares 3 of 5 numbers (15, 23, 33) with the draw of 17 February 2011 — its closest relative in 324 draws. Chance gave a match this close a 97% likelihood somewhere in that history.

From the draw just before (20 April 2011): nothing carried over. Chance says 53% of draws repeat at least one number.

Sum and shape

The numbers add up to 114 — the 75th percentile of all possible tickets, around a middle of 98. No two numbers side by side. 45% of draws have at least one such pair.

The longest wait in this draw

15 had not appeared for 15 draws. A number waits about 8 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 0.6× as often as an average ticket — less popular than most. At 30 million tickets sold, a winner on these numbers would keep about 3% of the jackpot.
