Morse Desk

How to play

Start: Open the game. Read the welcome, then choose Start at the desk.

The desk

The chart on the left is the Morse alphabet and numbers. Hide or show it with the small tab.
The top sheet is the incoming message.
The telegram card is where your answer is written. A short line on the card tells you what to do.
Enter Code is the telegraph key. Tap it for a short signal. Hold it for a long one. The spacebar does the same thing.
Hear it is the sounder. Tap it to play the message again.

Type the message you see. Read the Morse on the incoming sheet. Type the letters on the keyboard.
Tap the key to send this message. The incoming sheet shows letters. Send each one with short and long taps.
Type the message you hear. The incoming sheet is blank. Listen, then type the letters. Tap Hear it if you missed it.
Hold the key to match each mark. Timing practice. Fill each short or long mark by holding the key.

Backspace erases. A wrong letter or a wrong tap shakes the card. Get the whole message right to finish the word.

You start with Read. Other items unlock as you finish words. Once a skill is open, you can check or uncheck it.

If no skill is checked, the desk still gives you a Read round.

You earn rank from words you finish and from percent correct.

New Clerk → Junior Clerk → Telegraph Clerk → Operator → Senior Operator → Station Chief → Morse Code Master.

Progress is saved in this browser on this device. Clearing site data resets the rank.

Students begin with Read. Send, Hear, longer words, sentences, and numbers unlock as they finish words.
One device per student is best. Headphones help for Hear.
Click once on the page if sound does not start. Then tap Hear it.
The ? button has the same play notes, plus a short history of telegraphs and where Morse still shows up.
Timing practice is inside ? if a student needs help with short vs long.
No account. No internet after the file is on the device.
