Draws in Binary
Each of the five white balls fits in seven bits. Stack them side by side and you get a 35-bit fingerprint for every draw. The question: do any of those 35 bit positions look biased?

How it works
Each number is rendered in 7-bit binary (big-endian). Rows are draws, columns are bit positions — 5 groups of 7 bits. A filled cell means the bit is 1, an empty cell is 0.
The bar at the bottom shows, for each of the 35 positions, what fraction of draws have that bit set. The target is the expected rate assuming a uniform draw from 1–69 — so positions far from that line would be suspicious. They're not.
A useful sanity check is the bit-flip rate: if draws were truly independent, about half the 35 bits should flip between any two consecutive draws. The observed rate is almost exactly 50%.
