Brazilian States, one flag a day. Name it from a zoomed-in close-up; every wrong guess zooms out. For supporters. Every day's close-up is one of the 27 flags in the Brazilian States set, the same set as the Brazilian State Flags quiz.
A flag puzzle that starts with a close-up of one small corner, a star, a stripe or a bit of an emblem, and pulls back with every wrong guess. It rewards knowing flags in detail, not just at a glance. There are dailies for the world and the US states, plus sets of regional and expert flags. If you've played Flagle, it's the same idea, six guesses to name a flag from a piece of it, except the flag zooms out instead of uncovering tiles, and there are US state and regional sets as well as the world.
