Game
Bigger
Two places, one number showing. Los Angeles County has more people in it than forty-one states, so states, counties and cities go in the same pile and you say which of the pair is larger.
Games
Three games about American geography, all of them built on the same census and boundary files as the reporting. Nothing here is trivia written from memory: every question is a real figure, and the answer is checkable.

City Limits
Every American city has a shape, drawn by a century of annexations and refusals. Here is one of them, with the number of square miles it covers. Name it.
Downhill
You are dealt twelve states and may name one city from each, every one smaller than the last. The hand is different every time, so there is no ladder to memorise.
