Its nearest twin

Shares 3 of 5 numbers (7, 12, 29) with the draw of 24 December 2010 — its closest relative in 287 draws. Chance gave a match this close a 99% likelihood somewhere in that history.

From the draw just before (19 January 2011): nothing carried over. Chance says 57% of draws repeat at least one number.

Sum and shape

The numbers add up to 104 — the 78th percentile of all possible tickets, around a middle of 88. Side-by-side numbers: 29–30. 49% of draws have at least one such pair.

The longest wait in this draw

30 had not appeared for 15 draws. A number waits about 7 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 1.9× 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.
