Frequently asked questions

It’s a memory game built around flags: you see part of a country’s flag with one color section highlighted, then rebuild that color from memory by dragging around a color wheel and sliding a brightness bar. Your guess is scored on how close it lands to the real color, five rounds at a time, up to 50 points.

Yes. The game is completely free to play: no purchases, no premium tier, and nothing locked behind a paywall.

No. There is no signup and no login. Open the page and the first round is ready to play.

Each of the five rounds is scored from 0 to 10 with two decimals, like 8.13, based on how close your color is to the real flag color. A perfect match earns 10, and all five rounds add up to a maximum score of 50.

Yes. The game runs in any modern mobile browser, and the color wheel and sliders are sized for touch.

The game draws from more than 240 world flags. Each round picks one flag and one part of it, like a top band or a canton, so no two games test quite the same memory. You’ll meet the classics early and the obscure ones when you least expect them.

Scores are stored on your device for now, so there is no global leaderboard to climb. After a game, the Share your score button previews your result image, then you can copy or save it and send it to a friend to see who knows their flags better.

Two colors can sit near each other on the color wheel and still look clearly different, and every screen shifts colors a little. Scoring compares the actual color values of your guess and the target in a perceptual color space, so it judges what is really there. The reveal screen shows both colors side by side, exactly as they were scored.
