Alien amp stacks are descending. Each one wears a Roman numeral on its grille, and only one thing can destroy it: the chord that numeral names in the key you are in. Chord Destroyer takes the part of music theory everyone skips, diatonic harmony, and turns it into an arcade game you can actually finish. Fly the guitar, read the numeral, fire the right notes. HOW IT PLAYS A stack descends wearing a numeral: IV, vi, ii. Work out which chord that is in the current key and fire it before the stack crosses the danger line. The right chord blows it apart. The wrong one is absorbed, and the stack lurches closer. In the key of D, vi is B minor. In the key of A, it's F# minor. The numeral means the same thing in every key, and once that clicks, it never stops being useful. THREE WAYS TO ANSWER • Multiple choice. Four chords, one right. Start here. • Name the notes. Spell the chord out: root, third, fifth. • Fretboard. Build it on the neck, on six real strings. Pick your input every time you launch a level, so the same key can be a warm-up or a proper test. 41 LEVELS Twelve major keys, then twelve minor keys, then seventh chords. A key-shifting boss waits after every third key. THE OSCILLATOR swaps the key underneath you every few seconds, and THE MODULATOR is the one at the end. 24 keys, 168 chords, one guitar. Clear it once and the campaign resets for a second pass while every level you have beaten stays unlocked, so you can keep running it without losing what you earned. PRACTICE Any key, any chord type, no progress saved and nothing on the line. Good for the ten minutes before a lesson. A chord chart sits beside it: every chord in every key, with the shapes to play it, open and barred. WHAT'S NOT IN IT • No ads • No subscription. One optional purchase opens the whole game, once, forever • No accounts and no sign-in • No analytics, no tracking, and no data collection of any kind • No servers of ours. Your app store handles the purchase, and nothing else ever goes out It runs entirely on your device. Your progress is yours and it stays there. Built for guitarists, students and teachers, and for anyone who has ever nodded along to "just play the four chord" without being sure which one that was.
