Its nearest twin

Shares 3 of 5 numbers (13, 31, 37) with the draw of 12 March 2015 — its closest relative in 1,600 draws. Chance gave a match this close a 100% likelihood somewhere in that history.

From the draw just before (21 May 2015): nothing carried over. Chance says 53% of draws repeat at least one number.

Sum and shape

The numbers add up to 105 — the 62th 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

31 had not appeared for 25 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 0.7× as often as an average ticket — less popular than most. At 30 million tickets sold, a winner on these numbers would keep about 2% of the jackpot.
