Classic Waterworks is a fast-paced card game where players race to build a leak-free pipeline from valve to spout using pipe cards. Each turn, players add copper (leak-proof) or lead (leak-prone) pipe cards to their line, while sabotaging opponents with leaky pipes. Leaks must be repaired using matching pipes or metal wrench tokens. Players manage a hand of five cards, drawing new ones after each turn unless using a wrench. The first to complete a continuous, leak-free pipeline of the required length wins. With simple rules and fun sabotage mechanics, its great for 25 players ages 8 and up.
