Number 18

In Lotto under the 5/90 · since Oct 2025 rules — 113 draws, 5 from 1–90.

18 looks unusual on its own — and unremarkable among 90 numbers

Drawn 14 times in 113 draws against 6.3 expected, +3.17σ. Testing all 90 numbers at once means about 0.9 should look this way by luck alone, so the threshold tightens to 1.1e-4 and this does not pass it.

What this cannot tell you

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: 18 is drawn with probability 5/90 tonight whatever it did last week.
