The gilt disk never stops turning; you only place two rim taps, and the chord locks the moment it falls—no dragging afterward. Think of it as cutting a moving sample: the short arc outside, upper right, is your reference. Closer echo pays more; a wide miss zeros that chord without ending you. Cross the red inner ban and the sitting freezes cold. Concentric decoy rings look tappable yet never take an endpoint. After enough valid chords the sample reshapes, spin climbs, and another decoy ring joins. The gate is three upright columns—preview, brief, start; cutting totals rest bottom-left while the sample arc itself replaces any top chrome.
Two rim taps drop a chord. Match the sample arc; crossing red ends the run.
