🕹️ GT Arcade
Theory as the game, not the quiz. Short, replayable arcade runs where the only way to score is to know — and every miss teaches you exactly why.
Prefer a structured challenge?
GT Game is the 25-level theory ladder with tiers, a daily challenge, and the leaderboard.
Circle Runner
Race around the real Circle of Fifths — hop to the dominant, the relative, the next chord in the progression. One wrong key costs a life.
Trains: Key relationships
Fretboard Frenzy
Notes rain down a string — tap the fret where each one lives before it falls off the neck. Naturals first, then accidentals and scale degrees.
Trains: Fretboard recall
Chord Invaders
Shoot only the chord tones. Friendly-fire on the 3rd ends badly.
Trains: Chord tones
Scale Dash
Endless runner — collect in-scale notes, one wrong note ends the run.
Trains: Scale membership
Interval Hopper
Jump exactly the interval called — distance is semitones.
Trains: Intervals
Rhythm Smash
Whack the mole on the right subdivision, locked to the click.
Trains: Rhythm & timing
