A focused, no-frills geography quiz covering countries, capitals, and flags. It does exactly what the name says, which is both its strength and the reason it is here rather than in the main list. Carmen Sandiego teaches geography through narrative and deduction. Capitals Quizzer teaches it through repetition and recall. Both approaches have value, and for a child who is specifically trying to memorise world capitals for school or personal curiosity, this is the more direct tool. The engagement score is honest: it is not a game you play for fun first and learn from second.
