Endless US State Flag Quiz

State flags on a loop, shuffled so you meet all fifty.

Endless deals from all 50 US states, and a full pass meets every one of them. The traps are measurable: 24 of those flags have at least one near-duplicate elsewhere in the set, the closest pair being Maine and Vermont. Proportions help more than people expect, 22 of the flags fly at 2:3, but there are 14 distinct ratios in play, so an unusually long or unusually square flag has already narrowed itself down before you look at the colours.

One state flag, no caption. Name the state that flies it. A dozen states put a blue field behind their seal and dare you to tell them apart, the distance and compass hints are how you narrow it down. You get 6 guesses. Every wrong one returns the great-circle distance to the target, a compass direction pointing at it and a proximity percentage, so a cold start is recoverable, two well-spaced wrong guesses will usually bracket the answer.

Endless draws from a shuffled bag, so you meet every one of the 50 answers before any repeats. At one a day the daily would take 50 days to cover the same ground, roughly 1.6 months. Endless does it in a sitting, which makes it the mode to drill in and the fastest way to turn the half of the pool you are guessing at into the half you know.

Endless has no schedule and no streak, so you can spend guesses testing a hunch. Nothing is recorded against a date, so a bad run costs nothing. The board reshuffles as soon as you finish one, and the bag carries on from where it was, so a long session keeps covering new US state flags. Full rules, including how the distance and compass hints are calculated, are on the how-to-play page, and today's single scheduled puzzle is on the daily board.
