Rotate the pipes to route water source-to-drain — plug the leaks, beat the timer.
Tap or click a pipe to rotate it a quarter turn clockwise; right-click or long-press turns it the other way. Connect every bolted inlet to its matching outlet with an unbroken run of pipe and leave no open end — an open end is a leak, and a leaking line never seals. Later blueprints add a second hot line with crossover cells that carry two utilities through one square, plus an electrical cable that shorts out if it shares a square with water outside an insulated conduit. Campaign works through twelve fixed blueprints, Daily gives everyone the same board each day, and Endless keeps growing the grid until the clock beats you.
