CHORD
DESTROYER
A MUSIC THEORY BLASTER
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.
THE GAME
A KEY-BY-KEY CAMPAIGN
Clear all 12 major keys, then all 12 minors, then 7th chords in the first 6 majors. Fight mini-bosses along the way and a final boss at the end that tests your tonal recall. 41 levels, 24 keys, 168 chords.
SHIFTING BOSSES
Amp stack bosses that swap keys mid-fight, drawing from the keys you just cleared. Their health is the cabs in the stack, and every hit knocks them back. THE OSCILLATOR waits after every third key. THE MODULATOR, at the end, draws from every major and minor key you have learned.
THREE WAYS TO FIRE
Multiple choice, name the notes, or build the chord on a real six-string fretboard. Pick your input every time you launch a level. Practice mode drills any key and chord type with nothing on the line, and its chord chart shows every chord in every key with the shapes to play it.

FAQ
Where can I get it?
Android is available on Google Play. And iOS is available on the App Store
What does it cost?
The first four levels are free, on both stores. One purchase opens the rest of the campaign and every key in Practice and the chord chart, once, with no subscription.
Do I need to know how to play guitar?
No. Multiple choice and name-the-notes need no instrument. The fretboard input is there if you play and want the real thing.
Does it collect any data?
None at all. There is no sign-in, no analytics and no tracking, and no server of ours for anything to be sent to. The only thing the app talks to is your app store, and only to ask whether you have bought the unlock. Your progress is a file on your own device. See the privacy policy.
