Practice flow
Replay the same mode whenever you want
This page keeps the region, mode, and modifiers fixed so you can compare runs, build repeatable geography practice, and learn how a modern 3D map of the United States behaves over time.
On repeat runs you can measure whether the back half of the map is getting easier, not just the countries you already know well. Flag prompts add another layer of repetition, so each replay ties visual identity back to a precise place on the map instead of leaving it as isolated trivia.
No-skip rules make this an especially clear benchmark: if your later runs feel calmer and cleaner, your recall is improving rather than being carried by skips.
