How to play Neon Circuit
Neon Circuit is a pipe-rotation puzzle bathed in neon. Each level hands you a grid of scrambled conduits with one humming generator on the left edge and one or more dark power cores on the right. Your mission is to twist the pipes, one quarter-turn at a time, until a continuous glowing path carries current from the generator to every single core.
Only two pipe shapes exist, and learning to read them is the whole game. Straight pipes carry current through opposite ends; elbow pipes bend it around a corner. Tap any pipe to spin it clockwise and watch the grid react — pipes that connect back to the generator ignite in brilliant cyan, while dead ends stay dim. That glow is your compass: chase it outward from the generator and let the bright network pull you toward the cores.
Every twist costs one unit of energy, and the meter is generous but not infinite — roughly three twists per pipe on the grid. Random spinning will drain the tank and kill the run, so think before you twist. Trace the route in your head first, then commit. Clear all four grids, growing from 5×5 to 8×8, to light the whole circuit and bank your score.
Controls
- Rotate a pipe: tap or click it (spins 90° clockwise)
- Keyboard: arrow keys move the cursor, Space or R rotates the selected pipe
- Touch: tap pipes directly — fully playable on mobile
Reading the grid
Bright cyan pipes are live — connected to the generator right now. Dim pipes are dead. The fastest strategy is to grow the live region: find where the glow ends, twist the dim neighbor until it lights, and repeat. Elbows are the usual culprits at corners — a single elbow facing the wrong way is often all that separates you from a finished level.
Energy and scoring
You spend one energy per twist. Finish a level with 500 points per level number plus 10 points for every energy unit you have left — efficient wiring scores far higher than lucky spinning. Your best total across all four grids is saved in your browser.
