Murdox: Murder Mystery Puzzle

Someone has been murdered. Every suspect was somewhere in the building — and only one of them was alone with the victim. Read the dossier, put everyone in their place and name the killer.

Murdox is a detective logic puzzle: part sudoku, part murder mystery. Each case is a floor plan split into rooms, full of furniture. Place one suspect in every row and every column, follow the clues from their dossiers, and the truth falls into place.

HOW IT WORKS • One person per row, one per column • Walls divide the plan into rooms; some furniture can be sat on, some blocks the cell • Every suspect has a clue: "Violet stood next to the bed", "Luke was alone in the room" • Tap an underlined word to light up the cells it points to • The killer is the only person who ended up in the same room as the victim
