Guess the Capital is a free online geography quiz that tests your knowledge of world capital cities. You are shown 30 countries with their flag emojis and must pick the correct capital from 4 plausible options within 10 seconds. The quiz progresses through three difficulty tiers — Easy, Medium, and Hard — with wrong options drawn from real cities in the same country or region, not random world cities. Every answer reveals a fun fact about the capital. There are 195 sovereign nations in the world — how many of their capitals can you name?
Each round displays a country name and its flag emoji alongside four possible capital cities. Click the capital you think is correct before the 10-second timer runs out. Correct answers earn a point and show a green highlight; wrong answers or timeouts show the correct answer highlighted in green. After each question, a fun fact card appears with interesting trivia about the capital. After 30 rounds you see your total score, difficulty breakdown, fastest answer time, and a shareable rating.
Guess the Capital is a free 30-round quiz that shows you a country name and flag emoji, then gives you 10 seconds to pick the correct capital from 4 plausible options. Questions progress through Easy (rounds 1-10), Medium (11-20), and Hard (21-30) tiers, with a fun fact revealed after every answer.
The capital of Australia is Canberra, not Sydney or Melbourne. Canberra was purpose-built as the capital because Sydney and Melbourne could not agree on which city should hold the title. It became the capital in 1927.
Some of the hardest capitals include Sri Jayawardenepura Kotte (Sri Lanka), Ngerulmud (Palau — with only ~400 residents), Naypyidaw (Myanmar — built in secret with 20-lane highways), and Belmopan (Belize — moved from Belize City after a 1970 hurricane). Many people incorrectly guess Colombo, Koror, Yangon, and Belize City instead.
