Pipe Flow Empire: Plumber's Tycoon

Build perfect pipe grids! Fill truck cisterns with various liquids flowing through them. Connecting and installing pipes costs metal, and liquids from your storage are consumed when refueling trucks. Plan your moves in this engaging puzzle—and don't be afraid to dismantle old pipelines, as you'll recover part of the metal spent on their construction. Develop your fueling station by increasing storage capacity, unlocking new liquids, and signing contracts for new vehicles and trucks. Earn money and rating stars by completing refueling orders—fill cisterns with water, fuel, or acid. Spend your money on upgrades and modernization. Become the top fueler in the region and build your own empire!
