Arcade questions

Can I play these games without knowing Morse code?

Yes — four cartridges are marked 'no code needed': Repeater is pure rhythm memory, Cipher Files gives you the code chart, Morse Pairs is a matching game, and Echo Runner is a cave-flier. They teach the shapes of the code while you play.

Are the Morse code games free?

All nine games are free, with no accounts, downloads or in-app purchases. Scores and streaks save locally on your device — nothing is uploaded anywhere.

What kinds of Morse code games are there?

A daily word puzzle by ear (Daily Signal), a Koch-method listening trainer (Echo), a 60-second keying test (Key Master), a decode-under-pressure arcade (Signal Rush), rhythm memory (Repeater), codebreaking (Cipher Files), card matching (Morse Pairs), and two ultrasonic games you control by waving your hand — Echo Runner and Wave Surfer.
