Pipe Flow
Rotate copper pipes to link the pump to every drain before the countdown opens the valve. Clear growing boards, bank time bonuses and keep your three spare drops.
Pipe Flow is a pipe rotation puzzle with a ticking clock. Each board is a grid of copper pipe pieces on bright bathroom tiles: straights, elbows and junctions, plus a brass pump and a few drain grates. Tap a pipe to turn it a quarter turn and watch the connected network glow blue as you link pieces back to the pump. When the timer runs out the valve opens on its own and water rushes through, so every drain had better be on the line.
Levels keep coming for as long as you last. The board starts as a small 4x4 grid with a generous timer and grows a row or column every couple of levels, while the time allowed per tile shrinks and the number of drains rises. Clearing a level scores 100 points per level number plus 25 per drain and 10 for every second left on the clock, so opening the valve early with the Open valve button pays off. A leak that misses a drain costs one of your three drops, and you earn a drop back every fourth level. Lose all three and the run ends with your score on the board.
It is a quick-thinking plumbing puzzle for players who like logic under light pressure. Tip: start at each drain and trace backwards, since a drain grate only has one opening and that fixes the neighbouring pipe.
How to play
Tap or click pipes to rotate them so that an unbroken path runs from the pump to every drain. When the timer reaches zero, or when you press Open valve, water flows through the network. If every drain fills you clear the level and earn points plus a time bonus. If any drain stays dry you lose one of three drops and can retry the level; losing all three drops ends the run.
