Ring Reactor
Hold the charge. Synchronize the release.
Each row is one circular ring. Sector 6 touches sector 1. Gold ghosts show the next arc.
How to play
First discharge at least one ring. Then hold TWO completed rings and discharge them together. Recycling only one during the second calibration recovers coolant but does not complete the objective.
Choose a starting sector and flip the incoming arc's +/− polarity if needed. Arc lengths cycle 2, 3, 2, 1, 3, 1. An arc wraps from sector 6 to 1 and seats in the innermost groove where its entire footprint fits. Existing rings do not fall when others discharge.
A ring is ready only when all six cells are filled and every neighboring pair has opposite polarity, including the seam. Full rings with wrong polarity stay locked in place; they do not disappear automatically. Discharge clears ALL ready rings.
Twist rotates the chosen ring clockwise one sector, costing one coolant. This shifts partial gaps; it cannot repair same-sign neighbors in a full ring. Each discharged ring restores one coolant, cap three. Empty-ring twists and blocked insertions are free rejections.
24 arcs. After the last arc you may still discharge ready rings. No coolant, no fitting arc and no ready ring means a stall. Undo reverses insertion, twist or discharge even after completion or stall. Selection and polarity changes are free. Untimed; touch or Tab/Enter.
