A clear study set
What does “world flags” mean here?
This quiz uses a defined 195-country study set: 193 United Nations member states plus the Holy See and the State of Palestine, the two UN non-member observer states.
Country counts can depend on context. Taiwan and Kosovo are not included in the default scored set for this MVP. The full methodology is stated openly rather than presented as the only possible count.
One set per UTC day
A daily challenge without spoilers.
Every player gets the same ten flags, order, and answer options on the same UTC date. Your first completed result is kept in this browser, so a refresh does not quietly reset the score.
The shared result contains only the date, score, time, and a simple answer pattern. It never lists the countries or shows flag thumbnails.
Questions
About the quiz
How are missed flags reviewed?
A missed flag becomes due immediately. Correct recall gradually schedules it further into the future, while “Again” moves it back into the near-term queue.
Where is my progress stored?
