Invaders are falling. Your only weapon is Morse code. Morse Invaders is a Space-Invaders-style arcade game that teaches you real Morse code as you play. Every falling invader carries a letter or a word — key in its dot-dash pattern before it reaches the bottom, and it explodes. Miss it, and you take the hit. There's one control: a single telegraph-style key. Tap it for a dot, hold it for a dash — just like a real operator. No menus of buttons, no busywork. Just you, the key, and the code. HOW TO PLAY • Tap the key for a dot, hold it for a dash • Match an invader's full Morse pattern to destroy it • Tap a falling invader anytime to reveal its code if you get stuck • Survive as many waves as you can and chase your high score THREE WAYS TO PLAY • Learning Mode — letters are introduced gradually using the Koch method (the standard order for training your ear to recognize Morse code), with periodic quiz waves that hide the hints to test what you've actually learned • Normal Mode — all letters in play, hints available on tap • Words Mode — full common English words fall instead of single letters, and you key in the entire word as one continuous stream of dots and dashes Fall speed adjusts to difficulty automatically — longer patterns with more dashes fall slower, giving you time to think through trickier code. NO CATCH Morse Invaders is completely free, with nothing locked behind a purchase. No ads, no accounts, no data collection of any kind. If you enjoy it and want to help keep it on the App Store, there's an optional one-time note with a link to buy the developer a coffee — entirely optional, never required. Whether you're a ham radio operator brushing up, a student learning Morse code from scratch, or just want an arcade game with a real skill behind it, Morse Invaders turns practice into something you'll actually want to play.
