Its nearest twin

Shares 4 of 5 numbers (6, 7, 18, 28) with the draw of 5 October 2012 — its closest relative in 1,100 draws. Chance gave a match this close a 57% likelihood somewhere in that history.

From the draw just before (19 April 2013): nothing carried over. Chance says 61% of draws repeat at least one number.

Sum and shape

The numbers add up to 78 — the 45th percentile of all possible tickets, around a middle of 80. Side-by-side numbers: 6–7, 18–19. 52% of draws have at least one such pair.

The longest wait in this draw

28 had not appeared for 22 draws. A number waits about 6 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 0% of the jackpot.
