Turn any message into dots and dashes, just like old-school telegraph operators.
Turn this message into a real game: create a virtual lock your players must crack open.
Morse code turns every letter into a sequence of dots (short signals) and dashes (long signals). Letters are separated by a space, words by a forward slash (/) — a system built to be transmitted by sound, light, or vibration, not just read on paper.
It's named after Samuel Morse, who developed it in the 1830s for the electric telegraph, revolutionizing how fast a message could cross an entire country. For over a century it was the universal language of sailors, radio operators, and armed forces around the world.
For a treasure hunt, Morse has a great twist: you can send it without writing a single word, by tapping on a table, flashing a flashlight, or whistling. That turns a simple coded message into a full-blown performance for your players.

Start with the shortest, most common letters: E (one dot), T (one dash), then A, I, N, S. With a reference grid in front of them, most kids can decode a short word within a few minutes.
American Morse (used on 19th-century telegraph lines) relied on variable spacing between signals, which made it hard to automate. International Morse (ITU), simpler and fully standardized, largely replaced it — and it's the version used today, including in this tool.
Yes — on CrackAndReveal you create a lock whose answer is the word decoded from Morse. Players translate the code and type their answer online, and the lock opens automatically, with no adult needed to check every solution by hand.
Yes, mainly in amateur radio and aviation, where some beacons still transmit it. It's also widely used in education and games, since it's quick to learn and can be sent in creative ways — light, sound, even vibration.
With CrackAndReveal, your coded message becomes a virtual lock to crack: players decipher your code, enter the solution and reveal your surprise.
