Match mechanical city elements: gears, pistons, pipes, bolts, nuts, and wrenches. The gameplay features an “Electric Pulse” mechanic—every 10 seconds, an electric current travels along a path; if the current crosses the path you are about to connect, that path is temporarily blocked for 1 second. Gameplay: Connect identical cards using a path with a maximum of two turns. Later stages introduce “overpasses”—special grid spaces that allow connections to cross over other spaces (creating a multi-layered effect).
The 1,640 levels are divided across ten city districts. Each level has a 105-second time limit. Later stages (beyond level 1,500) introduce “steam valves”—activating a valve clears an entire row of obstacles, though it can only be used once per level.
