Murder mystery logic puzzles

Walk the crime scene like a Sudoku grid: one suspect per row and column, every alibi cross-checked against the floor plan. Read the cards, place each person, and find who was alone with the victim. Every seed is a brand-new case — rooms, furniture, clues, and one solution. Randomize below or share a Seed ID to replay the same mystery.
