Looking at this image, right off the bat you can tell that this is somewhere in Spain, Latin America, or maybe a neighboring country. This is because most of the text on the image is in Spanish, like what’s on this sign. However, there’s something very unique in this image that distinguishes it from other countries. That is the Aeropuertos Argentina 2000 logo.

Here’s a side by side comparison:

As you might tell from the name, this image is from Argentina.

Examining this image, there’s a very unique characteristic: the shape of the land bordering the water. Doing a reverse image search using this image, you find that this is a view of the Alexandria Corniche, a famous place in Egypt. Looking up images of this place, these are some of the results:

The landscape of the challenge image is very similar to these search results, with the sand, the color of the pavement, and some of the rocks. The building styles and lamp posts also match. That was enough to confirm that this is Egypt.

Immediately opening the image, it is obvious that this image is from India, or a neighboring country like Pakistan, Bangladesh, Nepal, or Sri Lanka. This is because of the Devanagari script used on the sign. This is the script that many Indian languages like Hindi use. More hints suggesting this is a village (gaon) in India are the landscape, the motorbikes, the fact that the people have cows in their homes, and the condition of the road.

However, the real nail in the coffin is this:

This doorway has the Shubh Labh, a traditional Hindu auspicious symbol. This was enough for me to determine this was in India.

This image has something very unique that can be used to determine its country. No, it’s not the landscape or the side of the road. Rather, it’s this:

Doing a simple reverse image search using this reveals that this is the Hebel Hotel. However, one should always be cautious with image searches as they can generate false positives. So, looking up this actual hotel, this is one of the image search results. This is unmistakably the same as the building in the challenge image. Looking into this hotel more, we find that it is in Australia.

This was one of the harder images (I had initially approached this from trying to find the exact gas station). However, once again, this country can be determined from just one thing: the script. Inspecting the gas station, we see it has a very unique script on it. The script is rounded and has many loops. This matches with the Burmese language’s script. This is also enough to determine that this is in Myanmar, although the right-hand side driving also helps support that conclusion.

This was another hard image. The landscape (Banana trees and a lot of greenery) suggests this is in a subtropical or tropical country (shocker that the country is exactly on the equator!). However, there’s one niche factor that distinguishes its country: the bollard. This bollard with the distinctive color scheme is unique to Ecuador.

There’s one feature of this image that nails down its country. That is the speed sign.

The yellow sign narrows it down to a few countries: Finland, Sweden, and Iceland. Looking up each country’s speed limit signs, we see the following:

A sign in Iceland	A sign in Finland	A sign in Sweden

While there are slight differences, the sign in the challenge image resembles the Iceland sign most.

This was a hard image (this is actually the only image we got wrong on our first attempt, and our 2nd attempt was correct!). The landscape is very unique with rugged terrain, a lot of erosion, and rocky mountains. Additionally, the road sign is similar to Russian road signs. After some trial and guessing, we figured out it was Kyrgyzstan.

The way we found this image was similar to Image 4. This has a very unique building, the church:

Doing a reverse image search with this part of the image, we find that this is the Jesus Is The Answer Church (shocker!). Looking more into this, we find that it is in Ghana.

This image seems daunting at first, but it’s just like Image 5. We can find it using the language. Specifically, inspecting this part of the image, we see that it is in Russian. However, Russian is used in a few countries, so we tried finding this exact store. We couldn’t do that, but we found that this is a Euroset store. Here’s a little information about Euroset: Euroset (Russian: Евросеть ) was Russia’s largest mobile phone retailer. For us, this was enough to know this image is from Russia.
