Feedback:

  - It'd be great to be able to move the map around, zoom in / out - staying in one place feels a bit restricting.
  - For some smaller countries you can't actually see where they were once the ring is put over them
  - Once a country has been identified it'd be handy to see their neighbouring countries to add some more context to where a country is.
  - It'd also be nice to learn a bit more about a country (e.g. unique things about it) that may help further cement the idea of a country so that it's more than just a name on a map.

Great application of spaced repetition beyond cards.

A few observations & thoughts:

- With remote islands somewhere in the oceans, the last zoom level isn't very effective since the map will essentially only show the island you're supposed to identify.

- The map's resolution could be higher.

- The challenge (top right) doesn't work for me in Firefox for Android. It always tells me I have guessed wrong (as if I had accidentally tapped somewhere on the map) when in reality I haven't even made a guess in the first place and was waiting for the game to tell me which country to identify.

Last summer I put together a flag quizzing game with my niece, who's a geography nerd: https://flagsaroundthe.world/

I think minimally contrastive examples work well for learning, i.e. you want to first learn to distinguish between broadly different categories, and focus on more and more similar examples over time. This little app doesn't have scheduling at all, it just samples examples based on previous responses, so sampling examples you got right exponentially less often as you keep answering correctly. I think sampling has some interesting advantages to SRS scheduling actually. Add new "items" becomes a straight sampling problem, where you can set a constant probability for each item that hasn't been seen yet.

Not to scope creep, but it would be great if users could pick from 1 or 2 themes. Or maybe just refactor it so that changing a global var from the javascript would let you change the colors.

edit: also the collective north and south poles take up about 60% of the zoomed out map. I bet you could crop most of antarctica and a significant portion of the upper northern hemisphere without degrading the experience.

Front of card: country name, plus possibly: recognizably large segment of world map containing that country, without highlighting.

Back of card: same graphic, with that country colored.

Determining whether you got it right is self-evaluation in Anki; if you thought of the correct map shown in by the back of the card, you hit the good button, otherwise bad.

This clever paradigm in Anki means that deck authors don't have to develop UI for the user to specify correct answers.

Say you want to go from dog breed names like "Yorkshire terrier" to photographs (rather than photo to name). How would you develop a UI by which the machine could test you and confirm that you know? Probably multiple choice is all we have. Multiple choice with too few choices gives the answer away to some extent. Too many choices will overwhelm your mobile device screen. You could ask the use to draw the animal. That would be time consuming and require talent not directly related to memorizing dogs.

With self evaluation, you don't need it. You just imagine a Yorkshire terrier as best as you can. Then if you think the back of the card is close to what you were thinking off, you hit Good. If you imagined a Westie, or German Shepherd, so that you are surprised and dismayed by the unexpected Yorkie image, then you hit Bad.

- After someone selects the right country, you should add country labels to the map for a second or two before transitioning so that context can reinforce the learning ("oh it's right next to Chile!") - Maybe show sattelite view for the same reason? So people can learn to ID countries by mountain ranges, lakes, etc?

Also, I absolutely love that it's so easy to start playing (no signup, no popups, etc)

Question: For the countries I know and select first time, I get them multiple times between countries. It's a bit odd to have to select England a couple of times, but the countries I don't know, I seem to get less often, or no repeats at all. Is this intended?

(edit) Question 2: Is there any scenario where you'd actually guess wrong more than once? After the first miss click, the country is highlighted. I don't see I'd ever get "You found country in 3 clicks".

* I like how the map moves around. It helps nail down relationships to neighbors * I don't mind a few extra "Where's canada", even though it's not that useful * I'd like the pause between answers be shorter. * Small countries are impossible to see when zoomed out on the first exposure, even when selected right. I find myself knowing the area it's in (ie, central america) but not which exact country. So selecting it right when zoomed out doesn't get me the correct answer.

Edit: OK I suspect there's a clear bug, because over the first 15 country or so, the only one I didn't know how to place (East Timor) hasn't been asked to me again after like 20 times asking me stupid thing like Greece and Algeria in a loop.

I can identify all mainland countries but have really hard time with the island nations in Oceania and the Caribbean. Would love to have an option to select which specific area I want to practice with.

Also for countries that I can identify with first click, I have to keep clicking until the cycle is complete. It make sense to zoom and ask to identify the countries again, but maybe stop after getting it right continuously ~3 times?

The data is also a bit more up to date w.r.t. the problems pointed out by sibling comments like changed names, different claims, distinguishing territories from countries.

Also commented in the original post.

But that's minor. Really fun project!

I suppose I'm slightly more geographically aware than average, but certainly by no means that good at geoguesser type games in the past. Even so, it felt way too easy for me. I got the first 40-50 correct before I closed it because it wasn't challenging enough for me.

I know where these countries are. I still had to select all of them at least 5 times each before I got another country.

Spaced repetition != immediate repetition.

Please fix this. If you have something correct, it should move it to the back of the stack.

Other than that, great.

Also, why is Antarctica on there?

I did a lot of sporcle grinding back in the day to learn all the countries of the world. Memories unlocked!

only slight thing is that i wish the map had more contrast, apart from that this is great

  Known: 87%

I am your classic american who would embarrass themselves if publicly tested on this. Never done spaced repetition outside of index card analogs, and I like the idea

I'll have to click more to experience the `spaced repetition` bit, just getting an early comment in to cheers you

I was wrong!

But the fact I get credit for knowing roughly where a country is, and then it zooms in, is a great idea. And well implemented.

I am going to try this for a bit and, if it works well, I'll ask my son (8yo) to consider adding it to his daily habits.
