Its nearest twin

Shares 3 of 5 numbers (17, 22, 34) with the draw of 13 January 2013 — its closest relative in 1,109 draws. Chance gave a match this close a 100% likelihood somewhere in that history.

From the draw just before (29 April 2013): 12, 30 carried over. Chance says 51% of draws repeat at least one number.

Sum and shape

The numbers add up to 115 — the 68th percentile of all possible tickets, around a middle of 103. No two numbers side by side. 43% of draws have at least one such pair.

The longest wait in this draw

34 had not appeared for 5 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 0.9× as often as an average ticket — about as popular as most. At 30 million tickets sold, a winner on these numbers would keep about 2% of the jackpot.
