Its nearest twin

Shares 3 of 5 numbers (10, 18, 19) with the draw of 21 September 2013 — its closest relative in 1,269 draws. Chance gave a match this close a 100% likelihood somewhere in that history.

From the draw just before (5 October 2013): 10, 20 carried over. Chance says 60% of draws repeat at least one number.

Sum and shape

The numbers add up to 92 — the 67th percentile of all possible tickets, around a middle of 83. Side-by-side numbers: 18–19, 19–20. 51% of draws have at least one such pair.

The longest wait in this draw

19 had not appeared for 15 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 1.4× 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.
