Dark Panel Puzzle is a portrait logic puzzle built around a cross-linked breaker panel. Tap one ceramic lamp to toggle it and its orthogonal neighbors, read how each move changes the circuit, and switch every light off.
Twelve handcrafted panels grow from compact four-by-four boards into denser six-by-six service grids. Every panel is free to open and reset, even with zero coins. Optional coins buy one solver-backed breaker hint, while efficient no-hint blackouts earn the strongest three-star inspection rating. Progress, best ratings, and the coin wallet stay saved locally on your device.
Toggle cross-linked lamps and power every midnight circuit down.
