How to play

Every flag is split into layers – a background, a pattern and sometimes a symbol. Choose the right piece for each layer to recreate the flag.

Choose your continents
Play Europe, Asia, Africa, North America, South America or Oceania – or all of them at once. Countries appear one at a time in random order.
Build the flag
Pick one option per layer. Get it right and the next country appears. Answer every country correctly to win.
Use your lifelines
A wrong layer is marked so you can change your choice. You have three lifelines per game – when they’re gone, the next mistake ends the game.
