Here's what I found: For each guess, Worldle calculates a proximity score from 0 to 100 -- higher is better. Each row is basically a quantized proximity score meter, from 0 to 100 in increments of 20. If you get at least half-way to the next increment of 20 (i.e. to the next green square), you get a yellow square, too.
Example: If your proximity score for a guess is 63, you'll get 3 green squares and two blank (white or black) squares, i.e. GGGBB. If your score is 71, you'll get three green squares, and since 71 is at least half-way to 80 (i.e. >= 70), you'll also get a yellow square, so GGGYB.
The proximity score is round(100*(MAX_DISTANCE_ON_EARTH - d)/MAX_DISTANCE_ON_EARTH). Though that max distance is defined to be 20,000,000.
This is the important part: https://github.com/teuteuf/worldle/blob/67db30bdf79c0965c19a...
The earth is bulging at the equator (or getting flatened pole to pole) due to rotation. https://en.wikipedia.org/wiki/Equatorial_bulge
This is almost true (in real life). The meter was originally defined as 1/10,000,000 of the distance from the equator to the north pole. Given that the earth is a fairly "nice" sphere, the maximum distance between any two points on earth is very close to 20,000,000 meters.
But because of this original definition the equator will work out to about 40000 km.
You have to add the fact that earth is almost spherical to go, from there, to “the length of the equator is about 40 million meters”.
Reading that Wikipedia page, I think it already was known when the meter was defined that the polar diameter of the Earth is smaller than its equatorial diameter.
There's some difference (~7km, if we believe wikipedia) attributable to the original measurement of Earth's circumference being off, and much much more difference (~67km, ten times as much) attributable to the fact that the earth is slightly oblate. (In other words, meters were defined by reference to the polar circumference, but the equatorial circumference is larger than the polar circumference is.)
One minute of latitude is always 1nm
The equator is more than that because of the oblateness of the spheroid.
And nowadays, the meter is defined in terms of natural units (time and the speed of light) in a way to be compatible with the original definition by the meridian.

That's extremely deceptive and non-obvious unless you read through the documentation. One of the appeals of Wordle is that it is an extremely intuitive game which doesn't require rule reading.
Consider the possible “center” of France. There’s probably some village in France proper with a monument, but unless you eject Guiana and Réunion I think it must be in the Atlantic somewhere.
Also, this is a map game, so for me it's pretty intuitive that it is the center of the hull. Maybe with some error due to projection (not sure how they implemented the map), but should not be a problem for solving the puzzle.
I don't follow. How does this being a map game make it intuitive that the distance outputs are based on hull centers? To me, closest border would seem be the most intuitive reading of the distance...this being a map game.
If you poll 10 random people, I guarantee 10/10 would say that they consider borders to be the intuitive means of measurement of distance between two countries, not their (hull) centers.
First of all; no, not at all. The arrow hint can work if countries are considered a mass, not a point, it simply means that there can be times when there are any number of correct arrow designations.
Second of all, even if countries are considered as single points for the arrow hint, that is not the issue being presently discussed: that of the distance hint, which is a separate hint from the arrow hint. Countries can be considered as single points for the arrow hint, and as masses for the distance hint.
In my opinion, using a different measure for the distance and direction would have been even more confusing. It’s also a lot harder to program for a silly web game.
(This is all news to me. I somehow assumed that French Guiana and British Virgin Islands were independent countries.)
> In 1801, Louverture issued a constitution for Saint-Domingue [now Haiti] that decreed he would be governor-for-life and called for black autonomy and a sovereign black state. In response, Napoleon Bonaparte dispatched a large expeditionary force of French soldiers and warships to the island, led by Bonaparte's brother-in-law Charles Leclerc, to restore French rule. They were under secret instructions to restore slavery, at least in the formerly Spanish-held part of the island.

As for French Guiana, it was actually an extreme penal colony at that time (also, it was briefly held by Portugal). It became a department in 1946.
If you use only the extreme boundaries then it gets a lot more interesting and I would say that the center is closer to the center of the Earth than to its surface.

Median is great for removing outliers.
I think the "right" way to display the distance would be from the closest points in the guessed and target territories. So United States and Canada, sharing a border, would be "0 km", while Canada and Mexico would be whatever the shortest path from border to border would be (like 2,000km?)
I have a feeling that's a bit more difficult than centers, though. But it wouldn't be a problem as far as outlying territories go; the image is of a contiguous landmass, not the entire country.
So in your hypothetical scenario....this hypothetical player would know that the only country Canada has a land border with is the USA, but not know what the USA looks like so as to be able to solve this without first guessing Canada?
This seems improbable to me. Chances are that if someone knows enough about a country that it's a 'single neighbor' country, or that it has a 'single neighbor' country, they will also know what the country looks like.
For example, if someone instantly knows that if they typed in Haiti it must then be the Dominican Republic, chances are very high that they wouldn't have typed Haiti because they also know what the Dominican Republic looks like. Much like chances are high that if someone knows that Canada only borders the USA, they also wouldn't have typed Canada in the first place, but would have guessed USA right away.
This is quite an understatement.
When people talk about how far one country is from another, chances are extremely unlikely they are referring to how far their central points are from one another.
But which country do you pick the extreme edge of, and which country do you pick the nearest point of? For example, if measuring US<->Canada, do you pick the extreme end of Canada or the extreme end of the US?
For every point in both territories, find the closest point in the other territory. From these pairs of points, find the pair with the largest distance. That distance is your Hausdorff distance.
It also stops me from bingeing, which is a big plus.
There's also a version with vector maps, and multiple other decks with varying fields in the cards and amounts of info. In my experience, decks are a matter of personal preference to a large degree—seeing as ideally you're dealing with them closely every day. So you might want to take a look at different ones and choose for yourself: https://ankiweb.net/shared/decks/geography
edit - hid my answer in case it wasn't as obvious to others.
Yes, and you get hints on distance and direction when wrong.
Compare this to drawing from 195 countries to guess 195 countries.
Yeah it’s not as fun as Wordle, kinda interesting for a few plays though.
On the other hand, I got Nepal in one, which I'm unreasonably proud of.
I wish the rotation would be on by default (the distances are enough of a hint), or at least work if I turn it on.
- lots of country guesses raise an error saying it doesn't exist. Such as "brasil".
- if you zoom on the map, there are flashings of the underlying map layer with country names...
- I got to find the exact match of "French Guiana (France)"...
In English it's spelled with a "z", and they're probably using an English dictionary?
Bit problematic, think an auto complete might make life easier for guessing
It also makes Firefox consider all your add-ons invalid when it next does a signature check, removing tracking protection and any custom tab bar you have, practically requiring you to restart the browser to continue using it as a browser. It also messes up "reopen last tab", opening something random instead, sometimes with a mangled URL.
I should just modify the game's code instead but so far it has been easier to write a bash oneliner that changes the date, presses F5 on the page, and changes it back, hoping Firefox doesn't do its ~hourly sig check during that moment. Sometimes it needs an F5 while the time is set correctly because the certificate isn't valid for far-out dates. (No idea why it works other times, it really shouldn't.)
1. Similarity in latitude
2. Similarity in longitude
3. Similarity in size
4. Similarity in population
5. Similarity in GDP

This is something that is unequivocally true, yet I get mildly irritated/frustrated (is there a word for combination of these two?) when people use google or something to "get words".
> There are settings to rotate or hide the map here, so we’re not all playing the same game anyway.
Wordle has hard mode too. But in this case you see the map before given this option. And at least the rotation doesn't work for me.
But I doubt HN could agree on what is good sporting wordling. Some of us like to guess with no sources save our minds; some of us wrote code to generate optimal strategies. And like, it’s super easy to just delete lines from the share button output, if you feel embarrassed. We all had fun with it differently, at different skill levels, which made it a special phenomenon.
If you compare with friends, tell em what tools you use. They can say you cheat, or you’re cheating yourself, but if you’re having fun and being honest, you’re playing it right.

Edit: Removing solution and replacing it with COUNTRY_CODE.
Today's (17 Feb) is easy for me. But gosh, last few days were really tough, mostly countries that I'm not aware of or don't hear a lot.
Got 2 bordering countries then looked at map.
Fun game!
