Reading the draws and working out what chance predicts.
In 2by2 under the 3/26 · Oct 2022 – Nov 2022 rules — 48 draws, 3 from 1–26 (an earlier era).
Drawn 4 times in 48 draws against 5.5 expected, −0.70σ. Each draw is independent: after 25 draws away it is exactly as likely tonight as a number drawn yesterday.
Drawn 4 times in 48 draws · average wait 5.3 draws · longest completed wait 13 · waiting 25 draws now
a completed wait — darker is longer the wait still running — a lower bound, not a finished gap
Too few completed waits to plot a distribution for this number alone.
Sort a draw and 7 has a favourite seat — chance gives a small number the low positions more often. That is the shape of sorting, not of the machine.
Seen most often with these — chance gives every partner about 0.3 shared draws, and the leaders are simply the ones that came out ahead this time.
Never drawn alongside 18 of the other 25 numbers; chance expects about 18 such strangers by now. Every pair →
Under the crowd model, 7 is picked about 1.54× as often as an indifferent choice — 1st most popular of 26. That changes nothing about whether it comes up, and everything about how many ways a jackpot on it would be shared.

Nothing here predicts the next draw. A number’s history is a record of a fair machine’s past, and the machine keeps none of it: 7 is drawn with probability 3/26 tonight whatever it did last week.
