Water Flow
Rotate copper pipes to link the tap to the drain, then open the valve before the timer ends. Every leak costs a drop, and the boards keep growing.
Water Flow is a plumbing puzzle set on a sandy workshop bench. A tap feeds water in from the left side of a grid of copper pipe pieces, and a drain waits somewhere on the right. Tap any pipe to turn it a quarter turn, build one continuous channel between the two, then press FLOW and watch the water run through your work, tile by tile.
The first board is a compact 4x4 grid with a hint to get you started, and each completed drain moves you to a slightly larger board, up to 8 columns by 9 rows. Every level has a countdown bar, and when it empties the water is released automatically, ready or not. If the route has a gap, water sprays out of the broken joint, you lose one of three drops, and you get a moment to fix the leak and try again. Connecting quickly earns a time bonus on top of the level reward, so a fast, clean solve pays best.
This pipe connecting puzzle is a good pick for players who like spatial reasoning with a dash of pressure. Tip: trace the route from the drain backward before you rotate anything, and leave the straight filler pieces alone, since they are often decoys that do not need to move.
How to play
Tap pipes to rotate them and build a connected path from the IN tap on the left to the OUT drain on the right. Press FLOW or Space to release the water; it also flows by itself when the timer runs out. A complete path scores points plus a time bonus and opens the next level. A broken path leaks and costs one of your three drops.
