Its nearest twin

Shares 3 of 5 numbers (8, 13, 17) and 0 of 1 stars with the draw of 28 April 2021 — its closest relative in 1,222 draws. Chance gave a match this close a 100% likelihood somewhere in that history.

From the draw just before (22 December 2021): nothing carried over. Chance says 50% of draws repeat at least one number. Stars: 2 repeated (17% expected).

Sum and shape

The numbers add up to 78 — the 14th percentile of all possible tickets, around a middle of 105. No two numbers side by side. 42% of draws have at least one such pair.

The longest wait in this draw

36 had not appeared for 17 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 0.8× as often as an average ticket — less popular than most. At 30 million tickets sold, a winner on these numbers would keep about 3% of the jackpot.
