Its nearest twin

Shares 3 of 5 numbers (12, 21, 29) and 0 of 1 stars with the draw of 14 April 2010 — its closest relative in 308 draws. Chance gave a match this close a 79% likelihood somewhere in that history.

From the draw just before (22 September 2010): nothing carried over. Chance says 43% of draws repeat at least one number. Stars: none repeated (10% expected).

Sum and shape

The numbers add up to 109 — the 30th percentile of all possible tickets, around a middle of 125. No two numbers side by side. 36% of draws have at least one such pair.

The longest wait in this draw

12 had not appeared for 33 draws. A number waits about 10 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 1.3× as often as an average ticket — more popular than most. At 30 million tickets sold, a winner on these numbers would keep about 5% of the jackpot.
