Guide the flow from IN to OUT before the chamber pressure gets out of control. Rotate each brass pipe to build a connected route. Once the water starts moving, wet pipes lock in place and every bad connection risks a leak. Think ahead, react quickly, and reach the drain before the next surge. FEATURES - 140 handcrafted pipe puzzles - Continuous animated water flow - Pressure, leaks, and escalating urgency - Three-star scoring based on efficient moves - Local achievements and progress tracking - Optional music, sound effects, and haptics - No ads and no account required Early levels teach the basics with generous setup time. Later chambers introduce larger networks, faster flow, and tighter move targets. Every level is solvable, but earning all three stars takes a clean route and a steady hand. Guide the flow. Fill the sea.
