Make a murder mystery with your own class in it

Pick who was there, draw the rooms they know, and the clues write themselves. Print it as a worksheet, drop it into your slides, or share a link.

Play one first

Three finished cases. Open one, share the link with your class, and see what comes out before you make your own.

All ready-made cases

Why make your own

  • Your people

    Paste your class list and everyone gets a face you can still adjust: hair, glasses, cap, hijab.

  • Your building

    Describe where the rooms are and the floor plan gets drawn, or drag the walls yourself until it matches your corridor.

  • Your pace

    From gentle to devious. Every case has exactly one answer, and that is checked before you print it.

What you get out

A case is not finished while it only exists on this screen. Everything below comes out of the same case.

  • An A4 worksheet, ready for the copier
  • An A3 poster for the wall
  • A PowerPoint with real text, not a screenshot
  • A booklet of ten cases, ramping up in difficulty
  • The floor plan as its own image
  • A card per suspect, to cut out
  • A QR code for the whiteboard
  • A link that carries the whole case inside it

In three steps

  1. 1

    Who was there

    Paste the names. Adjust the faces until they look right.

  2. 2

    Where it happened

    Describe the place or draw it yourself, then put the furniture in.

  3. 3

    Lay the body down

    The clues follow on their own. Print it or share it.

What is a murdoku?

A murder puzzle on a grid. Everyone stands in their own row and their own column, each suspect has their own card saying what they saw, and the murderer is whoever was alone with the victim in the same area.
