PA Treasure Hunt Number Heatmap

All 30 numbers, shaded by how often each has been drawn across 99 draws. If they fell perfectly evenly every number would sit at 17; in practice they range from 11 to 28.

That spread is not a pattern. Over 99 draws a gap of this size between the most and least drawn number is exactly what chance produces — the darker cells are not warmer, and the pale ones are not due.

Each cell: the number, how many times it has been drawn, and its difference from the even share.
