The rules
How to Play
Identify each country from four progressively easier clues. The fewer clues you need, the more Mercator Points you earn.
Three countries a day
Every player worldwide gets the same three mystery countries, refreshed at 00:00 Finnish time.
One guess per clue
Pick a country from the search bar. A wrong guess unlocks the next, easier clue.
Country Wars
Sign in and choose the country you represent. Points from your daily challenges go directly to your nation, not the country you guessed. Guests can play all three challenges, but their scores stay personal and cannot be claimed later.
Weekly crown
Every Monday at 00:00 Finnish time, the leader becomes Smartest Nation of the Week and scores reset.

No timers, no speed bonus — only how many clues you needed. Each challenge can be scored once.
Fact-checked clues
Clues are written by AI each day, checked against reputable sources such as UNESCO, the UN, the World Bank, Britannica and official government sites, and never repeated for the same country. After each round you can read the underlying facts and their sources.
Mercator Points are a fictional game score — not a measure of any country's real-world intelligence.
