Who Did It? — Mystery Party Game

Who Did It? is a multiplayer mystery party game where players receive secret roles, investigate AI-generated crime stories, analyze clues, discuss their theories, and vote to discover the criminals hiding among them.

The game supports 4 to 10 players in two different modes: Classic pass-and-play on a single device and Room mode where each player uses their own device online. It is available in Arabic and English and works on Web browsers and Android devices through cross-platform play.

1. Setup

Enter 4-10 player names, choose a crime category or leave it random, and pick your language. The game generates a unique mystery with characters connected to the case.

2. Secret Roles

Each player receives a secret character with a name, profession, and relationship to the crime. Criminals know each other and must hide; investigators must uncover the truth.

3. Story & Clues

A crime story is revealed followed by clues in each round — material evidence, witness observations, documents, and relationship traces. Every clue has two interpretations.

4. Discussion & Voting

Players discuss theories using the built-in timer, then vote to eliminate a suspect. Tie votes trigger a tie-breaker round.

5. Reveal & Win

Eliminated players reveal their role. Investigators win by catching all criminals; criminals win by surviving or reaching equal numbers.

Classic Mode

Pass one device around. Each player views their role privately, then the group discusses. Perfect for local gatherings, families, and classrooms.

Room Mode

Create a room and share a 6-digit code. Each player joins from their own device. Supports cross-play between web and Android.

Investigation Unit Mode

A cooperative 2-4 player mode with specialized roles — Detective, Doctor, Evidence Technician, or Tech Analyst. Each role has unique information, and the team must combine findings to make a final accusation.
