Its nearest twin

Shares 3 of 5 numbers (35, 36, 37) with the draw of 28 September 2010 — its closest relative in 266 draws. Chance gave a match this close a 93% likelihood somewhere in that history.

From the draw just before (29 December 2010): 29 carried over. Chance says 52% of draws repeat at least one number.

Sum and shape

The numbers add up to 171 — the 100th percentile of all possible tickets, around a middle of 100. Side-by-side numbers: 34–35, 35–36, 36–37. 44% of draws have at least one such pair.

The longest wait in this draw

36 had not appeared for 11 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.
