Match various robot parts: gears, screws, circuit boards, chips, motors, and screwdrivers (icons representing parts, not the electronic devices themselves). The gameplay features an “assembly progress” mechanic—clearing a pair of parts fills a progress bar. Once full, you can summon a small robot to automatically clear any pair of icons (limited to twice per level).
Controls: Tap two identical parts to connect them with a path (allowing for up to two turns). Later levels introduce “conveyor belts”—icons on these belts shift one space every 5 seconds, altering the board layout.
The 1,220 levels are organized into ten workshop tiers. Each level has a 120-second time limit. Board sizes range from 6×6 to 12×12. In later stages (beyond level 1,100), “short-circuit tiles” appear—paths cannot pass through these tiles, forcing players to route around them.
