Fill all 9 cells with countries that satisfy both the row and column categories for each intersection.
You have 12 guesses total. A country can only be used once per board.
Score = sum of points from each filled cell. Higher is better! Empty cells score 0.
How scoring works
Each cell scores 5 to 100 points based on how unexpected your answer is. Countries are ranked by population among all valid options for that cell:
80–100 pts
Rare pick — small or obscure country few would guess
30–79 pts
Mid-range — a solid but not obvious choice
5–29 pts
Common — large, well-known country most people guess first
Example: For "In Europe" + "Island Nation", picking Iceland (common) scores low, but Malta (less obvious) scores higher.

How is my score calculated?
Each filled cell scores 5–100 points based on your country's population rank among all valid answers for that cell. The smaller/less obvious the country, the more points.
Why do famous countries score less?
Most players think of large countries first, so picking them is considered "common" and earns the minimum. Rare picks demonstrate deeper knowledge and are rewarded.
How many guesses do I get?
12 total for 9 cells — you can afford up to 3 wrong answers. Both correct and incorrect guesses consume one from the counter.
Can I use the same country twice?
No. Each country can fill only one cell per board, even if it satisfies multiple intersections.
What happens when I run out of guesses?
The board ends. Any unfilled cells score 0 points, but you keep what you've earned.
Why was my correct-looking answer rejected?
The country must satisfy both the row and column categories. Matching only one is not enough.
Is the daily puzzle the same for everyone?
Yes. The daily board is seeded by the date, so all players worldwide get the same categories. It resets at local midnight.
Does practice mode affect my daily stats?
No. Daily and practice statistics are tracked separately.
What is the "Best" button?
After the board ends, it reveals a high-scoring reference board so you can see which rare picks you missed.
How are a flag's colors determined?
Only the colors of the flag's background fields (stripes, bands, quadrants) count. Colors that appear only inside a coat of arms, emblem or seal are not counted — for example, Spain's flag is red + yellow, even though its coat of arms contains blue and purple. This keeps categories like "Flag with only 2 colors" consistent with how people usually describe flags.
What is HDI based on?
HDI is the Human Development Index published by the UN Development Programme. It's a 0–1 score combining life expectancy, education (years of schooling) and gross national income per capita. GeoRiddle uses the most recent published values; categories like "HDI above 0.90" and "HDI below 0.55" reflect the standard "very high" and "low" tiers.
1Start with the hardest cell. Solve the intersection with the fewest valid countries first — it narrows what's left for everyone else.
2Think beyond the obvious. The first country that jumps to mind is usually the lowest-scoring one. Pause and look for a less famous match.
3Check both axes carefully. A wrong guess still costs a guess. Verify the country matches the row and column before committing.
4Use search aliases. Typing "UK", "USA", "Holland", "Burma" or similar shortcuts will find the official country.
5Save your rare picks. If a tiny country fits several cells, place it where the competition is thinnest — the rarity bonus will be highest there.
6Practice mode is your lab. Use it to learn which countries fit which categories — mistakes there don't touch your daily streak.
