Spot the fake flag before the glass breaks.

Two flags, one real and one doctored — the stripes in the wrong order, a band the wrong width, a star missing, a shade very slightly off. Tap the real one to cross the bridge. Tap the fake and it shatters underneath you. An endless run: no checkpoints, no pauses, just further.

Two German flags side by side: the left one has its stripes in the order yellow, red, black; the right one is the real black, red, yellow — Germany, with the stripes the wrong way up

How it plays

Pick a region — World, Europe, Americas, Africa, Asia, Oceania, or Regions (the home nations, states and unions) — then start crossing. Each shows its real pool size, and a narrow region widens out rather than running dry.
Tap the real flag of the pair shown. The fake is a genuine mutation of the real one: a stripe reordered, a band resized, a shade shifted, a charge moved — never a random unrelated image.
One wrong tap and the glass breaks. A single rewarded-ad revive per run gets you back on your feet; otherwise the run ends and your score banks to the leaderboard.
Difficulty ramps continuously — panes get harder to tell apart and flags get less familiar the further you go. Every fall tells you exactly what was wrong, so a loss is a lesson.

Differences that are real

The fakes are the differences actual flags have from each other. Ireland runs green-white-orange and Côte d'Ivoire runs orange-white-green. Poland is white over red; Indonesia is red over white. Chad and Romania differ only in a shade of blue. Nothing is a random distortion.

No accounts, ever

Progress and scores live on your device only. There's no sign-in, no server-side profile, nothing to lose if you switch phones without backing up. Every flag is real artwork from flag-icons under the MIT licence — nothing scraped, and a national flag carries no trademark.
