Its nearest twin

Shares 3 of 5 numbers (19, 22, 31) with the draw of 19 November 2014 — its closest relative in 1,739 draws. Chance gave a match this close a 100% likelihood somewhere in that history.

From the draw just before (18 January 2015): 22 carried over. Chance says 55% of draws repeat at least one number.

Sum and shape

The numbers add up to 97 — the 57th percentile of all possible tickets, around a middle of 93. No two numbers side by side. 47% of draws have at least one such pair.

The longest wait in this draw

14 had not appeared for 27 draws. A number waits about 7 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 1.5× 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.
