What it teaches
Around twenty-three flags and the countries they belong to. Flags are the easiest way into world geography because they are already everywhere a child looks — on shirts, on number plates, at the start of a football match.
The capital city is shown once the answer is right, so a second fact arrives attached to the first rather than as a separate thing to learn.
How it works
A flag is shown and the countries are the answers. Three levels change how many questions a round holds and how many countries are offered, from three up to five.
A wrong answer is not accepted and the flag stays. Missed flags come back through the daily review the next day.
What to look for
The confusable pairs are the interesting part: the Netherlands and Luxembourg, Ireland and Italy, Poland and Indonesia — the last two being the same two colours the other way up. Those are worth a sentence out loud when they appear.
Find the flag asks the same thing backwards, which is harder.
