A question about the city. Answered in the camera.
Within Mastercard’s “Okut, Geç & Eğlen” campaign, we built one clearly bounded piece: the Istanbul knowledge quiz. The participant stays in the camera view while a question about the city appears above them.

Make the city the content.
“Okut, Geç & Eğlen” brought Mastercard into Istanbul’s transit stops and invited passengers onto their phones. The campaign idea, media and other mobile experiences came from its agency and production partners.
Our brief was the knowledge quiz. Its idea is simple: a passenger is already somewhere in Istanbul, so the questions are about Istanbul. The person stays visible in the camera, the question sits above them, and a familiar place becomes the subject of a personal answer.
One question, one answer, one response.
The campaign brings the participant to the phone; the quiz takes over from there.
Arrive from the campaign
The campaign’s entry point opens the quiz on the participant’s phone.
Stay in the frame
The camera view keeps the person at the centre of the screen.
Read the question
An Istanbul-themed question appears above the participant.
Answer and see the result
The response and feedback appear inside the same camera view.
The person in the frame. The city in the question.
A frame from the campaign film shows the quiz in use; the second image places it in its campaign setting.
Istanbul knowledge quiz
The participant stays in the camera view while the city-themed question appears above. Question, person and answer share one screen, so the moment reads clearly at a glance.
Inside a wider campaign
The quiz is one of the experiences a passenger could reach from the campaign’s transit placements. It follows the campaign’s brand language rather than introducing its own.
Where the quiz sits.
The original campaign montage shows the transit placements and mobile experiences around the quiz. Everything beyond the Istanbul quiz belongs to the campaign’s other credited partners.

Keep the moment simple.
The person stays visible
The camera view keeps the participant in frame; the quiz is layered around them rather than replacing them.
The city as the subject
Questions draw on Istanbul, linking the activity on the phone with the place the passenger is standing in.
Campaign language first
The quiz carries the campaign’s visual identity so it reads as part of the same story.
Interaction logic, in four steps.
User action → system response → branded payoff. The campaign supplies the entry; the quiz handles everything inside the camera.
