Vector Field (Stage 19) introduces directional beams: each lock draws a line that points toward the next likely spawn. The line's brightness tells you how confident the prediction is, the underlay glow tells you how hot that quadrant currently is. Most first-time players treat the beams as visual noise and miss the entire mechanic.

How to read a beam
- Direction. Beams point from your last lock toward the predicted spawn. Watch where they end, not where they start.
- Core brightness. A bright sharp core means a high-confidence prediction. A faint core means the field is uncertain — wait for the sweep.
- Underlay glow. The wide soft underlay marks how saturated that quadrant is. A heavy underlay means contacts there will decay faster — prioritize.
Position your eyes, not your fingers
The instinct on Vector Field is to chase contacts with your tap finger. Don't. Move your gaze to the beam endpoint between sweeps so you're already looking at the spawn when it appears. The tap becomes confirmation, not search. Players who do this consistently clear the stage twice as fast.
Streak management on a directional stage
Color streaks still trigger purges in Vector Field, but the field biases the next spawn toward your streak color. Once you're at ×2 on a color, the field genuinely wants to give you the third. Hold the streak — don't take an off-color lock just because it's nearer.
Common mistakes
- Treating beams as decoration. They are the minimap. Ignoring them is playing the stage blind.
- Chasing low-confidence beams. A faint core can mislead. Wait one sweep before committing.
- Tapping in the wrong order. Vector field sometimes spawns priority pairs. Wrong-order locks add a saturation penalty.
A clean run, in five steps
- First lock — anything matched. You're seeding the field.
- Second lock onward — track the brightest beam, look at its endpoint.
- At ×2 streak, hold for the third pair. The field is helping you.
- On purge, the field resets. Treat the next lock as a fresh seed.
- If saturation passes 70%, ignore beams and hunt the nearest streak color.
