Its nearest twin

Shares 4 of 5 numbers (3, 5, 7, 15) with the draw of 13 September 2015 — its closest relative in 1,152 draws. Chance gave a match this close a 24% likelihood somewhere in that history.

From the draw just before (14 June 2017): 3 carried over. Chance says 50% of draws repeat at least one number.

Sum and shape

The numbers add up to 69 — the 8th percentile of all possible tickets, around a middle of 105. No two numbers side by side. 42% of draws have at least one such pair.

The longest wait in this draw

15 had not appeared for 10 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 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 2% of the jackpot.
