Morse code puzzle and shareable decode challenge
Encode a short secret, get a link, send it to a friend (or your future self). They hear or see the Morse, type the plaintext, and get a pass/fail. Built for escape-room energy and classroom dares — not for graded exams. Payload stays client-side in the URL; nothing is stored on a server for scoring.
When to use
Party / classroom puzzles; sharing a CW tease in chat; practicing decode under a soft timer; silent on-screen Morse play when audio isn’t allowed.
When not
Don’t put sensitive passwords in a share URL. Don’t expect accounts, leaderboards, or anti-cheat. Don’t use this as a graded exam.
Assumptions
Challenge payload rides in the URL (`?c=`) and is decodable client-side; optional timer; audio and/or on-screen Morse. Keep messages short.

How it works
- Author a short phrase and copy the share link.
- Friend opens the link, hits Play (or reads on-screen Morse), types a guess.
- Check scores locally — no upload, no account.
plaintext → pack into shareable ?c= → player loads → play/reveal → score typed guess locally
Gotchas
- Huge messages make ugly URLs — keep challenges short.
- If someone forwards the link with the answer in the chat, the puzzle is over.
- Browser autoplay may block sound until they tap Play.
- Anyone with the link can see the Morse — treat it as a game, not a vault.

How sharing works
Author a short phrase → we pack it into ?c= (base64url) → anyone with the link can Play and guess. Nothing is stored on our servers for the secret. Keep messages short; ugly URLs and spilled answers in chat both kill the fun.
House rules worth agreeing on
- Ears only vs “translator allowed” — say it before you share.
- No passwords or personal data in puzzle links.
- Silent play: on-screen Morse is enough; flashlight for blink style.
Audience hub
Puzzle landing: for/puzzle. Casual decode without sharing: translator. Ear warmups: listen.
