Its nearest twin

Shares 3 of 5 numbers (10, 11, 22) and 0 of 1 stars with the draw of 7 October 2015 — its closest relative in 745 draws. Chance gave a match this close a 100% likelihood somewhere in that history.

From the draw just before (27 May 2017): nothing carried over. Chance says 50% of draws repeat at least one number. Stars: none repeated (17% expected).

Sum and shape

The numbers add up to 76 — the 12th percentile of all possible tickets, around a middle of 105. Side-by-side numbers: 10–11, 11–12, 21–22. 42% of draws have at least one such pair.

The longest wait in this draw

11 had not appeared for 20 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 2.3× 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.
