Its nearest twin

Shares 2 of 5 numbers (13, 24) with the draw of 18 October 2010 — its closest relative in 170 draws. Chance gave a match this close a 100% likelihood somewhere in that history.

From the draw just before (20 October 2010): 11 carried over. Chance says 52% of draws repeat at least one number.

Sum and shape

The numbers add up to 108 — the 62th percentile of all possible tickets, around a middle of 100. No two numbers side by side. 44% of draws have at least one such pair.

The longest wait in this draw

21 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 0.6× as often as an average ticket — less popular than most. At 30 million tickets sold, a winner on these numbers would keep about 3% of the jackpot.
