Morse code is a way to send letters using short and long signals. A short signal is a dot. A long signal is a dash. Each letter has its own pattern of dots and dashes.
The letter E is one short signal. The letter T is one long signal. The Morse chart shows the rest of the alphabet.
You will try three short examples: reading Morse, sending Morse with the key, and listening for Morse. Then you will choose what to practice from the Practice list.
The Morse chart shows each letter as a pattern of short and long marks. Numbers show on the chart when Numbers is checked. You can hide or show the chart with the tab. On the last level it starts hidden.
The big sheet is the incoming message. Sometimes it shows Morse. Sometimes it shows letters for you to send. Sometimes it is blank because you need to listen.
The telegram card is where your answer is written. Type on a keyboard, or on a phone use the letter keys under the card. Backspace erases.
The telegraph key sits under the card. Tap it for a short signal. Hold it for a long one. The spacebar does the same thing. The key lights up while you are sending.
The wooden sounder also sits under the card. It plays Morse out loud. Tap it if you want to hear the message again.
The game starts with a short tutorial: one Read, one Send, and one Hear. After that it points you to the Practice list on the left. Check the modes you want. Longer words, Sentences, and Numbers stay off until you turn them on.
Messages start as single letters and short words. They get longer as your rank grows. Speed also rises with rank. The last rank is Morse Code Master.
Timing practice helps you get used to how long to hold the key. You can start it here any time.
A telegraph sent messages over a wire using electricity. Morse code turns letters into short and long signals so they can travel that way.
One office tapped the message on a key. Another office heard those signals and wrote the letters down. That is how people sent news, train orders, and personal messages before phones were common in every building.
Later, the telephone, radio, and the internet took over most of that work.
SOS is a Morse distress signal that a lot of people still recognize.
Amateur radio operators still use Morse. Some ships and aircraft keep it as a backup way to send a short message.
You can also tap Morse on a pipe or flash it with a light if you cannot talk or send a text.
