Its nearest twin

Shares 3 of 5 numbers (11, 18, 28) with the draw of 18 April 2017 — its closest relative in 2,039 draws. Chance gave a match this close a 100% likelihood somewhere in that history.

From the draw just before (15 September 2017): nothing carried over. Chance says 50% of draws repeat at least one number.

Sum and shape

The longest wait in this draw

10 had not appeared for 9 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 2.3× 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.
