Strategy note

How this prompt scores — and how to think about future ones.

Krillion rewards obscure-but-valid answers: anything steam powers, heats, cleans, or cooks counts. The 554 Deep Cut answers (85 pts) cover steam-powered ships, machinery and industrial processes — pick household+industrial niches over the obvious train/kettle answers, which everyone else is already typing.
