Neon Circuit

Neon Circuit is a tile-rotation puzzle built around a clear objective: connect the power source to every terminal by rotating pipe segments into a continuous glowing circuit. Each tap turns a tile 90 degrees, so progress depends less on speed than on reading how each segment will fit into the larger route. The premise is simple enough to understand immediately, but the boards expand from 4x4 grids to 8x8 networks with as many as five terminals that must be powered at the same time. Its structure gives the challenge a steady sense of escalation: 40 handcrafted levels are spread across 8 zones of increasing complexity. Completing a circuit is only the first layer, because earning three stars requires solving a level in fewer moves than par. That move economy makes every rotation matter, especially when a short-term connection can leave another terminal awkwardly isolated. The most reliable approach is to plan from the whole board rather than fix one pipe segment at a time. Looking ahead to distant terminals helps reduce wasted taps, and the best solutions often come from arranging several future connections before closing the circuit.
