Its nearest twin

Shares 4 of 5 numbers (11, 13, 26, 29) with the draw of 13 June 2010 — its closest relative in 561 draws. Chance gave a match this close a 39% likelihood somewhere in that history.

From the draw just before (24 October 2011): 11 carried over. Chance says 63% of draws repeat at least one number.

Sum and shape

The numbers add up to 99 — the 87th percentile of all possible tickets, around a middle of 78. No two numbers side by side. 54% of draws have at least one such pair.

The longest wait in this draw

13 had not appeared for 16 draws. A number waits about 6 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 0.9× as often as an average ticket — about as popular as most. At 30 million tickets sold, a winner on these numbers would keep about 1% of the jackpot.
