3191 is a resonance collector built around a rule that arcade catchers almost never use: the tray is tuned to one gem frequency at a time. Falling amethyst, garnet, smoky quartz, and moonstone share the same shaft, but only the active tone scores, fills the meter, and keeps the dish intact. Wrong catches detune the plate. When the meter peaks, the vein shifts and the target changes without a pause. Some crystals split mid-air into two diverging shards. A limited harmonic pulse briefly draws matching stones toward the tray. Prismatic legendary splinters fall slowly and count in any resonance, then lock into a relic vault. Eight chambers escalate sway, density, split chance, and shift speed. A crystal codex mixes Brazilian gem localities with the invented craft of vein resonance, so every run is a lapidary decision, not a reflex scoop.
