Morse code decoder puzzles for play
Open a shared challenge, decode by ear or by sight, or create your own in the challenge tool. Built for escape rooms, classrooms, and group chats.
When to use
Hosting a quick puzzle; joining a friend’s link; practicing decode without “lesson mode”; classroom races with one shared URL.
Better elsewhere
Serious Koch progression → for/learn. Keep private data out of puzzle URLs. No global leaderboard in v1.
Assumptions
Challenges are short; spoilers in chat defeat the point. This landing deep-links to the working challenge tool.

How it works
- Open the challenge tool to create or solve.
- Share a link or open one you received.
- Agree “ears only” if you don’t want translator cheats.
Create/open challenge → optional translator check → share offline
Gotchas
- Don’t put private data in puzzle URLs.
- If everyone uses the translator cheat, agree on “ears only” rules first.
- Huge secrets make ugly share URLs — keep them short.
