The game plays through a trimmed-down version of the story in the episode. Screenshots from the episode and speech bubbles are presented in a panel format. Near the end, the player can do an interactive email chat with Adil by choosing one of three pre-made questions, which Adil will respond to.
Arthur: I usually wear jeans, a shirt, and sneakers. What do you wear?
Adil: That sounds like what I wear. When it's warm, I wear tee-shirts, shorts, and sandals. When it's colder, long pants, a long-sleeve shirt, and maybe a sweater vest.
Arthur: What is your school like? Or are you taught at home?
Adil: My school is pretty big, and a little crowded. We have our elementary and middle schools together in one building. One good thing is that I get to learn a lot from older kids!
Arthur: Do you take your turban off before you shower?
Adil: That's a weird question. I am a Muslim, but only some Muslims wear turbans. I don't wear one. And of course people who wear them take them off before showering. It would get all wet.
Arthur: Do you have any pets, like a monkey?
Adil: What? Who has a pet monkey? They're wild animals.
Arthur: I really like to read. I go to the library all the time. Do you like reading?
Adil: I LOVE to read! My favorite books are books about Turkish history. It's so interesting.
Arthur: I love to ride my bike. Do you have a bike? If so, where do you ride?
Adil: I live in Istanbul, a really big city. It's crowded, and there is a lot of traffic, so we can't ride bikes that often. My apartment building has a small park, and sometimes I ride my bike there.
Arthur: How did you learn to speak Turkish?
Adil: Uh... everyone I know speaks Turkish, so I just learned it.
Arthur: Do you play video games? Which ones do you like?
Adil: I do play video games! Usually I play on a computer or a tablet. I like games where I can build things — like zoos and houses.
Arthur: Do you have a certain bedtime? I'm supposed to go to sleep at 9:00.
Adil: Yes, usually I go to bed at about 9:30. Right before bed my family has tea and a snack together. We eat walnuts, oranges, and apples.
Arthur: What kind of money do you use in Turkey?
Adil: Our money is called the Turkish lira. You can buy a delicious ice cream for just one lira!
Arthur: I love a TV show called "Bionic Bunny." Do you like TV or movies?
Adil: I don't watch them that often, but I do like TV and I loooove movies! Sometimes my friends and I even act out our favorite TV shows.
Arthur: What kinds of games do you play with your friends?
Adil: The best game is called celik comak. There are two teams, and a stick on the ground between them. The goal is to get the stick to your side!
Arthur: What's your family like? I live with my mom, dad, and two little sisters.
Adil: I live with my mother and father, and my little sister Ayse, who is VERY annoying!
Arthur: Do you have a favorite food? If so, what is it?
Adil: My favorite food it called manti. It's sooooo delicious. It's dough folded around a super tiny ball of meat (like a mini ravioli!).
Arthur: Is it hot living in the desert?
Adil: I assume it could be hot... but why are you asking me? I live in a big city!
Arthur: Do you have man-eating newts where you live?
Adil: You mean like tiny lizards that eat people? That's not even a real thing!
Arthur: Have you ever seen someone make a carpet fly?
Adil: Seems like a weird question. You mean like a magic show?
Arthur: What are your friends like? My best friend Buster is really funny!
Adil: My best friend is named Onder. He is so funny! But sometimes he gets in trouble for not doing his homework.
Arthur: What kind of weird foods do Turkish people eat?
Adil: What do you mean weird? I eat lots of good food.
Arthur: Do you listen to regular music, or just snake charmer music?
Adil: Uh, you DO know I live in Turkey, right? I THINK you're thinking about India. And I don't think THEY even have snake charmers anymore.
Arthur: So, you live in Turkey. Do you EAT turkey on Thanksgiving?
Adil: Arthur, I don't know what "turkey" is. Are you making a joke of some sort?

The line "maybe he was just being polite" is removed.

Alberto doesn't specify that he watched the show as a little kid.

In the episode, he lists first surfing, then skyscrapers, then ketchup.

Adil says "his sister" instead of Ayse's actual name.
There exists an unused question and a corresponding voice line in the game, in which Adil asks "What would YOU tell me or ask me in a letter?" It was intended for use between Arthur asking "Has anyone ever made an assumption about you? How did you feel?" and the ending slide of the game.
As of 2022, the Turkish government has changed the official spelling of the country's English name from "Turkey" to "Türkiye" (the Turkish spelling). This game, like the episode on which it is based, uses the country's former spelling.
