About this game

🎨 THE FLAG IS NOT SHOWN. IT IS DISTILLED.

You never see the flag. You see its colours with the share of area each one takes, or a small piece of it, or a sentence that describes it. From that, you work out the country.

It is a flag quiz for people who already know the flags.

🎨 PALETTE
The colours as bars, each one as long as the area it covers, with its percentage beside it. Nothing else: no shapes, no stripes, no emblem. The percentage is part of the question, not decoration — without it, Austria and Denmark would be the same question.

🇷🇴 NEAR-IDENTICAL
Four flags that really do look alike, each drawn at its true ratio. Chad or Romania. Indonesia or Monaco. The groups are not a hand-written list: they come from measuring the colour distance between every pair of flags.

🔍 CROP
A small piece of the flag, at full size. Sometimes it is obvious. Sometimes it is a rectangle of one colour and you are on your own.

🎭 FALSE FLAG
Four versions of the same flag. One is the real one and three have been altered: mirrored, with two of its colours swapped, or with one colour in another shade. You point at the real one. Every alteration is derived from the flag itself and checked twice — that it can be seen, and that it is not the flag of another country. Afterwards the card tells you what each fake had.

💬 QUESTIONS
A sentence instead of an image: which flag has 27 stars? And the other way round too — you get the country and pick the fact.

🗂️ DOSSIER
Three true clues about one flag — three stripes, no white anywhere, a canton in the corner — and only one flag fits all three. No clue is padding: take any one away and a second flag would fit. Every clue is derived from the flag itself. And the other way round too: you get the country and pick its dossier.

🔢 2715 IN TOTAL
That is how many questions there are, and it is not one per flag: the same flag comes back as a palette, as a crop, inside a group of near-identical ones and inside a sentence. Every one of them has exactly one right answer.

📇 THE COUNTRY CARD
After each answer: the name, the exact hex of each colour with its share, the official ratio and the date the design was adopted — with the source it comes from. What is not documented is left blank, and the game never asks about it.

📅 DAILY CHALLENGE
The same mode and the same questions for everybody, every day. One round. Keep the streak going.

🏆 MARKS, ACHIEVEMENTS AND YOUR WORST COUNTRIES
Best score, best streak and best time are kept per mode. The game also counts which countries you get wrong most often, and tells you.

🌍 195 FLAGS · ✈️ OFFLINE
Everything travels inside the app. No connection, no accounts, no sign-up, and nothing is downloaded while you play.

The flags are the same ones you already know. The question is whether you know them without looking.

What’s new

🎭 TWO NEW MODES

🕵️ DOSSIER
Three true clues, and only one flag matches all three. "It has blue. It has no stars. It is a tricolour." Work out the country without ever seeing it.

🎭 FALSE FLAG
Four versions of the same flag: one real, three altered — mirrored, two colours swapped, stripes reordered or the whole flag turned. Point at the real one.
