Guess the Flag is a free online geography game that challenges players to identify national flags from around the world. The quiz covers all 193 UN member states across eight increasingly difficult levels. Each round displays a flag and country name choices, increasing from three options in the first level to ten in the final level. Players receive instant feedback, can make up to two mistakes per level, and restart the current level if they do not pass. With colorful visuals, music, sound effects, and no signup or download required, it is an enjoyable way to test and improve your knowledge of world flags.
