πŸ“±Coming soon to theApp Store

β–¦ CASEBOOK

Who, with what, where, and why?

Each suspect had one weapon and was in one place. Work through the clues on a classic deduction grid until only one answer is left: whoever was where the body was found.

  • Rookie to Mastermind: 3 to 5 suspects
  • Motives from Inspector up
  • Lie Detector cases, where the murderer is the one who lies
β–š FLOOR PLAN

Who was alone with the victim?

Place everyone in the house, one per row and one per column, sudoku style. Furniture gets in the way, and the clues say who was where. The person alone in a room with the victim did it.

  • Constable 4Γ—4 to Grand Detective 7Γ—7
  • Chairs, beds, rugs, and things you can't stand on
  • Mark tiles off, check your work, undo
