Every number was expected about that many times after 212 draws, and they scatter around it. Warm means more than expected, cool means fewer — and a cold number arriving is exactly what cold numbers do.

Sum and shape

215

The longest wait in this draw

3 had not appeared for 35 draws. A number waits about 10 on average, and a wait this long was not a signal — the machine has no memory of it.

Gap & “Overdue” Tracker →

How many people held it

A line like this is played about 0.6× as often as an average ticket — less popular than most. At 30 million tickets sold, a winner on these numbers would keep about 82% of the jackpot.

    • Where chance put the count

    The rings take the ≈10M lines the counts imply and assume an evenly spread crowd. Furthest from that: Match 2 — 0 winners, 100% fewer than the 984k an even spread gives. The numbers drawn were noticeably less popular than average — a draw full of birthdays makes more small winners, a draw of high numbers fewer. That is the crowd, not the machine.
