50
Number 50, draw by draw
Drawn 31 times in 339 draws · average wait 10.8 draws · longest completed wait 33 · waiting 3 draws now
a completed wait — darker is longer the wait still running — a lower bound, not a finished gap
Where it lands in a sorted draw
Sort a draw and 50 has a favourite seat — chance gives a large number the high positions more often. That is the shape of sorting, not of the machine.
Never drawn alongside 3 of the other 51 numbers; chance expects about 2 such strangers by now. Every pair →
How many people play it
Under the crowd model, 50 is picked about 0.90× as often as an indifferent choice — 32nd most popular of 52. 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: 50 is drawn with probability 6/52 tonight whatever it did last week.
