Machine Room

Every machine, every set of balls, tested on its own

A lottery does not draw with one set of balls. The UK rotates four machines across a dozen numbered sets and publishes which pair drew each result. That matters, because a physical fault belongs to one set — a ball a fraction heavier than its siblings — and any test that pools a whole era averages it away with the sets that are fine.

This game does not publish a machine or a ball set.
