Signal Relay

Signal Relay is a cable-rotation puzzle drawn like a blueprint. Every grid hides one network. Tap a tile to turn it a quarter turn clockwise. Cables glow orange once they connect back to the tower. The grid is solved when every tile carries the signal and no cable end points into empty space. Signal strength From the Ridge region on, the signal loses 1 with every tile it passes. Diamond boosters restore full strength, so the line has to pass through them to reach far receivers. The small number on a receiver shows the strength that arrives. Features • 100 grids in five regions: Valley, Hills, Ridge, Highlands and Summit, from 4×4 to 7×7. • Move counter and par — the fewest turns needed. • Undo and three hints per grid; a hint sets one wrong tile right. • Optional tint for tiles already in their final position. Blueprint blue with orange current. Offline, no ads, no purchases.
