What the game is

Built to make Morse code a skill in your hands, not just something memorised.

  • See it as a tree

    Letters branch out from a shared structure, so you can see how dits and dahs combine instead of just memorising them.

  • A guided start

    New learners follow step-by-step lessons that build from the difference between a dit (·) and a dah (—).

  • Letters, numbers, or both

    Practice letters, numbers, or a mix, choosing whichever range fits what you are working on.

  • Tune the speed and timing

    Adjust WPM speed, the timing threshold between a dit and a dah, and the spacing between words to match your level.

  • Straight key and paddle, both

    Practice with a traditional straight key or an iambic paddle — both input styles are supported.

  • Track your progress

    See per-letter mastery, learning progress and your personal record on one screen.

Available in Korean and English. Signing in is optional, and only useful when you want to sync your progress across devices.
