This draw, read by every tool
What the site’s explorations say about the numbers drawn on 13 December 2011 — each beside what chance predicted. None of it says anything about the next draw.
Scored 57 of 100 across six shape features — more typical than about 64% of every possible ticket.
Times drawn before — chance expected 24 of each
Every number was expected about that many times after 153 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.
Frequency Explorer →Shares 4 of 7 numbers (18, 21, 42, 45) with the draw of 5 April 2011 — its closest relative in 153 draws. Chance gave a match this close a 65% likelihood somewhere in that history.
From the draw just before (6 December 2011): 29 carried over. Chance says 72% of draws repeat at least one number.
Carry-over / Déjà Vu →The numbers add up to 191 — the 82th percentile of all possible tickets, around a middle of 161. No two numbers side by side. 66% of draws have at least one such pair.
Sum Distribution →42 had not appeared for 10 draws. A number waits about 6 on average, and a wait this long was not a signal — the machine has no memory of it.
Gap & “Overdue” Tracker →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 77% of the jackpot.

The Unpopular Numbers Edge →Where the money went
The rings take the ≈22M lines the counts imply and assume an evenly spread crowd. Furthest from that: match_5_b — 661 winners, 12% fewer than the 754 an even spread gives. The numbers drawn were a little less popular than average — that is the crowd, not the machine.
