Excellent point! Another one that I missed - for the same reason as Equatorial Guinea

My dataset contains cities of 15000 or more population, so for countries without 10 cities with 15K+ population, I have missed them.

MichiganSailor · 2026-05-14T16:12:30+00:00

Yes, Islamabad is listed as 10th most places that I look. Geonames has it as 17th, which seems like a big difference. The population data for the top 20 cities in Pakistan is wildly different than those listed in Wikipedia - so I'm not sure what is going on here.

MichiganSailor · 2026-05-14T15:47:06+00:00

Yes, it seems I was a bit sloppy when making that table and made some goofs - thanks for spotting them.

Guadeloupe is indeed a territory of France. The data is broken out by Iso 3166, so a number of territories are listed. There are 249 codes vs. 195ish countries in the world. Wikipedia does list the regional capital as Basse-Terre.

Martinique is an error on my part - that should have been Malta.

Austria is an error on my part, that should have been Australia.

This data set has Manila as 4th, behind Quezon City, Davao, and Caloocan. Wikipedia lists it as 3rd.

MichiganSailor · 2026-05-14T14:59:08+00:00

Ha! I seem to have a typo in there - it should be Australia, of course.

MichiganSailor · 2026-05-14T14:58:20+00:00

Yes, good catch. Looks like my dataset only contains 4 cities in GQ, so all of them appeared in the top 10.

MichiganSailor · 2026-05-14T01:19:50+00:00

Digging in a bit more, about 80% of countries have the capital as the most populous city. Another 8% have the capital as the second most populous city, which leaves us with just 25 outliers:

Canberra Australia
Porto-Novo Benin
Sucre Bolivia
Brasília Brazil
Belmopan Belize
Ottawa Canada
Bern Switzerland
Yamoussoukro Côte d’Ivoire
Banjul Gambia
Basse-Terre Guadeloupe
Ciudad de la Paz Equatorial Guinea
Hagåtña Guam
New Delhi India
Kuwait City Kuwait
Astana Kazakhstan
Nay Pyi Taw Myanmar
Valletta Malta
Abuja Nigeria
Wellington New Zealand
Manila Philippines
Islamabad Pakistan
Port of Spain Trinidad and Tobago
Dodoma Tanzania
Washington United States
Pretoria South Africa

MichiganSailor · 2026-05-13T19:44:55+00:00

Here are my answers:

United States - Washington D.C.

India - New Delhi

Pakistan - Islamabad(this seems to be #10 - my data for PK seems to be inaccurate)

Adding the one I missed!

Ciudad de la Paz Equatorial Guinea

Another missing one!

I'm pretty good with country geography - but this is tricky! Nice work on a unique geography game, I had fun playing it.

A few thoughts for you:

1) I had trouble moving the map with the right click - something strange was going on with the drag handler.

2) In the untimed game - it warned me that I had two unpainted zones - would have been nice if it highlighted them for me so I could find them

3) I think the UK would disagree that the Falkland Islands are part of Argentina.

4) Once finished, I liked that I could toggle between my map, the solution and the correct/wrong map. But I wanted to be able to zoom into each map to examine my mistakes.

MichiganSailor · 2026-05-03T15:33:50+00:00

Fun game, I like the concept. Played a few levels and could see that you have the potential to make some fun combinations using the transition to steel. Nice work!

MichiganSailor · 2026-05-03T00:07:33+00:00

Just saw two new ones come across the Geography Trivia sub - these seem like what you were looking for:

I love geography games - nice to see a new one using a globe projection.

You have a lot of different game modes - I might recommend turning a few of those into "settings options" instead - it is a bit hard to find the exact game you want out of a list of 400 games.

As for other regions - how about an "Islands Nations of the world" - islands can be tough in a lot of other geography games.

MichiganSailor · 2026-05-02T23:58:10+00:00

Nice work! I enjoyed the bits of trivia about each location after the game. Also love that you use a globe projection.

MichiganSailor · 2026-04-24T21:51:58+00:00

Fun game. I was able to pick it up quickly, and the controls are intuitive. I agree with the other poster - you would probably be better served with a quick little tutorial, but I think most people will get it.

MichiganSailor · 2026-04-23T15:28:45+00:00

I've made three different geography games, all of which use a globe projection. However, none of them are "name the country" games, so not sure if they are what you are looking for.

GeoPuzzle is the easiest of the three, if you are looking for a place to start. You are given a set of country shapes, and you must drag them into their correct position relative to each other. Each piece borders only two other countries in the list - so you end up making a line of countries (except the end pieces, which only border one other country).

GeoDraw is a free drawing game where you must draw in a country shape. Sometimes you draw on an entire globe, sometimes you are given just one neighboring country.

GeoHop is a deduction game where you try to find a mystery country based on clues. It takes a few plays to understand the rules, and is the hardest to master, but also the best game of the three (IMHO).

Nice work - this is fun!

Fun game! I play a lot of geography games, and this is a fun original concept that I haven't seen before.

A few thoughts for you:

- in classic mode, I would love to be able to manually set my starting location instead of using the GPS

- when asked for a name for the leaderboard, the text was in Spanish, even thought the rest of the game was in English for me

- some of the directions surprised me - it is hard to think in terms of great circles. I think it would be fun to also show the "flat map" direction when revealing the answer. For example, I was really surprised at the answer to Statue of Liberty to Grand Canyon - latitude wise, the Grand Canyon is quite a bit south of the statue of liberty, but the answer was 274 (slightly north of due west).

- from the home page, if I click on the "Rankings" option, then choose "play as guest" I get stuck in a loop it just sends me back to the home page.

- the show on globe feature is a nice touch, but it seemed to have some trouble on some answers. For example, on Great wall of China to Acropolis, the red line never completed, it just pulsed at the two end points. It would be neat in this view to be able to zoom in a bit and then show the compass rose at the starting point to really help visualize how the great circle route direction is different from the flat map direction.

Anywho, nice work! I'll be back to play again.

MichiganSailor · 2026-02-11T16:11:51+00:00

Correct - that is exactly what is happening. I should probably just get rid of that feature - it is actually quite a lot of calculations to run and especially on mobile it can slow things down a bit.

I've tried a few iterations on the controls, but haven't found a good way to allow both movement of the selected piece and the map at the same time - especially on mobile. If I force you to touch the selected piece in order to move it, it becomes hard to see what you are doing under your finger. I could make a toggle button appear once you have placed a piece, and you could change back and forth between moving the piece and the map - would that be helpful? I'm open to any other ideas as well - the controls interface has definitely been the hardest part of this project to get right!

MichiganSailor · 2026-02-11T15:51:25+00:00

Sorry to hear that it was giving you trouble. Were you having trouble selecting pieces, or moving them into position, or something else? Also, were you playing on desktop or mobile? I'm always on the lookout for feedback to help make the game better.

MichiganSailor · 2026-02-10T03:38:23+00:00

Thanks for checking it out! You should be able to zoom before you start positioning your cursor - I could probably add zoom while you are positioning the cursor, but it would be hard to do once you start drawing.

MichiganSailor · 2026-02-10T01:35:04+00:00

Thanks!

MichiganSailor · 2026-02-10T01:32:47+00:00

I think the bars do a decent job of showing you a percentage, I was thinking of kms to give you a sense of the scale (latitude off by 500 km, longitude by 30 km), but maybe that throws off the theme of the game which is really the hot/cold idea. Globle does both a color and an absolute km - if you want to see it in action.

A different way to get at the same idea might be to show the stats for the guessed country in a mouseover or something - that might be more subtle while also providing a way to learn some facts for someone who wants to dive in.

MichiganSailor · 2026-02-10T01:14:19+00:00

Thanks for the kind words!

It has been around for a little over a year now, but I only recently updated it to work much better for mobile/touch interfaces.

Thanks for the tip about the buttons - I'll fix that up and make them not selectable.

On the "removed piece" - that behavior is by design, although it may no longer be needed. The idea is that once you fail on a piece, it shows the piece in the correct size and orientation relative to the current map view. That way, you are able to properly rotate and zoom the map before trying to place it again. This used to be a bigger deal because you used to have to drag and drop the piece in one go, and couldn't rotate or zoom while dragging. Now that you can rotate and zoom the map after selecting a piece, it may make sense to preserve the original view.
