About this game

Morse Master turns learning Morse code into a game.

TAP A REAL TELEGRAPH KEY
Key dits and dahs on a beautiful brass straight key — short press for
dit (·), long press for dah (—). Unlock the iambic paddle for
machine-perfect timing, just like real HAM operators use.

EXPLORE THE CODE MAP
Every letter and number lives on an antique treasure map, arranged by
its Morse pattern. Practice words or single letters, watch your mastery
grow letter by letter, and hide the ones you've conquered.

TALK TO REAL PEOPLE IN MORSE
Tune the radio to a shared channel and have a live QSO — every dit and
dah you key is heard by other players in real time, with a proper
channel log in dots and dashes or decoded text.

FEATURES
• Straight key and iambic paddle (one-time purchase)
• Adjustable WPM, dit/dah threshold, and word gap
• Per-letter mastery tracking with progress gauges
• Live multiplayer Morse channels with callsigns
• Multiple sidetone voices, haptic feedback
• Optional Google sign-in to sync progress across devices

Whether you're studying for a HAM license or just love the sound of CW,
Morse Master makes the code stick.
