The longest wait in this draw

18 had not appeared for 12 draws. A number waits about 9 on average, and a wait this long was not a signal — the machine has no memory of it.

  • Where chance put the count

The rings take the ≈3.4M lines the counts imply and assume an evenly spread crowd. Furthest from that: Match 4 — 690 winners, 30% more than the 529 an even spread gives. The numbers drawn were noticeably more 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.
