Try the art of deduction like Sherlock Holmes.
One photograph of a stranger's space. Read the clues, deduce who lives there.
Every day brings a new stranger's space. A desk, a room, a portrait. Your job is what Holmes did best: read the room for what it gives away, then name the person who lives there. The AI grades how close you got.
The question changes shape through the week: some days you write, some days you tap the photograph, pick the lie or put events in order. Meet all the case types →
The scene · what you see
A stranger's space arrives.
The main question
Who lives here, and what does a normal week look like for them?
Your answer · in the day's format
Write it, mark it, match it, or order it.
"A software developer, probably mid-career. The dual monitors and mechanical keyboard suggest a serious setup, the sticky notes hint at active debugging, and the worn dev hoodie reads casual office or remote work."
Or pin the evidence directly on the photo
Click Add pins bottom-right (or the FAB on mobile), then click anywhere on the photograph and write a short note. Pins are an alternative way to tag evidence; they get bundled with your prose but don't give extra points. Use either method, or both.
The verdict · what comes back

A confident read, Watson. The dual monitors and the worn dev hoodie did most of the work for you, and you saw it. The mug's joke and the sticky-note ritual escaped your eye, though.

MARK

Sharp choices, honest traps.
ORDER
Put time back in its place.

Three things that move the score
- Name specifics. "Nurse in her 30s" beats "a medical worker."
- Connect clues. Saying why turns a guess into a deduction.
- Write in any language. Turkish, English, whatever you think in.
