Can you build the flags of the world? START GAME Choose one or more continents you want to include in your game. The countries are presented one at a time in random order. THE GAME Each flag consists of two layers and any symbol as a third layer. You choose one option per layer to recreate the flag correctly. When you guess right, the next country is presented until you have gone through all the countries. You win when you respond correctly to everyone. RULES OF THE GAME If you respond incorrectly to a layer, it is highlighted with red. You then have the opportunity to change your choice for that layer. You get this opportunity up to three times per game. If you answer errors and have used all lifelines, you lose.
