Design a readable Morse puzzle

Start with an answer a player can verify

The audio example uses OPEN BOX with normal letter and word gaps. Its setup sheet provides the message, playback settings, answer and staged hints. Test the recording on the intended device before placing the clue in a room.

Make the reference and reading direction discoverable. Difficulty should come from the planned deduction, not a missing letter boundary, an inaudible speaker or an arbitrary alphabet change. A printed transcript can provide an equivalent route when audio is unavailable.

Add a second encoding only after the first works

The layered example decodes Morse into binary bytes, reads those as ASCII coordinate digits, then looks them up in a C/K tap-code grid. Each intermediate result is shown so a designer can reproduce the puzzle in reverse.

More transformations are not automatically more engaging. Observe a new tester, note where they lose the convention and offer a hint for that stage. A short clear puzzle can be better than three unexplained layers. We provide examples and a test checklist, not guaranteed solving times.
