About This Game

Welcome to The Unsolved Detective Agency

An AI-driven detective career simulation. Step into the world of The Unsolved, crack an endless stream of unique cases generated in real time by artificial intelligence, and uncover the truth through dynamic verbal duels. Together with your assistant, build an epic of deduction that belongs only to the two of you — one that never truly ends.

Every interrogation is a real conversation with an AI

Suspects aren't NPCs reading lines — they're played live by AI. They lie, they deflect, they test your patience, and they crack under pressure when you corner them with evidence. Ask anything; they answer. No scripted dialogue, no two conversations alike.

Cases generated by AI, in real time

Every case is created on the spot: the killer, the motive, the alibi, the web of clues — all generated live. No repeated cases, no memorized answers. Solving the mystery is a race against the generator itself.

Choose your style

Western classic, Japanese honkaku, or Republican-era Shanghai — a wide range of detective aesthetics to choose from. Whether you're a Christie devotee, a honkaku purist, or a fan of old Shanghai's charm, there's a cold case waiting for you.

Free investigation, clue-board deduction

Search the manor for every piece of evidence, catch contradictions during interrogation, pin your clues on the deduction board, and piece together the shape of the truth — then point your finger at the killer.

Share your case with a seed code

One string of code, one complete case. Send your generated case to a friend and let them solve it from scratch — you set the puzzle, they solve it. Who will catch the culprit first?

Your detective career is just beginning

Aya, your personal AI assistant: she'll guide you through your first case, offer just the right hint when you're stuck, revisit past cases with you — and even play a game of chess. Solve cases to rise in detective rank — your career, witnessed and accompanied by her. More content is on the way around launch.

Note: This game generates case content with AI in real time. You'll need your own AI service API key (entered in the in-game settings), and the game consumes that service's quota.
