Sudoclue: Mystery Cases

Read the clues. Place the suspects. Solve the crime. Start with 12 free cases, then unlock more mysteries with a one-time purchase. No subscription.

Every room tells a story. Every clue narrows the suspects.

In Sudoclue, a murder mystery unfolds on an illustrated floor plan. Read the witness statements, connect the clues, and work out where everyone belongs. Place one person in each row and column, then discover who was alone in the room with the victim.

The rooms, furniture, and people are part of the puzzle. A detail about a chair, a room, or someone’s position can change how you read the whole scene.

118 cases. 19 chapters. Investigate original stories across varied locations, from a puppet theatre and a rooftop apiary to a cable-car station. Start with compact 5 × 5 scenes and work your way through grids up to 10 × 10, with Rookie, Detective, and Mastermind difficulties.

Make your reasoning visible Keep candidate notes, mark impossible squares with an X, and undo a move when you want to revisit an idea. Your progress is saved, so you can return to an unfinished investigation later.

Hints that show the reasoning Choose a nudge, a step-by-step explanation, or a reveal when you need help. Follow the deductions on a separate demonstration board before deciding whether to apply the next move.
