The longest wait in this draw

35 had not appeared for 13 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 ≈10M lines the counts imply and assume an evenly spread crowd. Furthest from that: Match 3 — 69,054 winners, 11% more than the 62k an even spread gives. The numbers drawn were a little more popular than average — that is the crowd, not the machine.
