Connecting is only half of it

Pipeflow is a liquid puzzle game about drawing pipe between matching

wells. Link every color and you are halfway there — the board is only

solved when every last cell is filled with flowing liquid. That one

extra rule turns a simple connection puzzle into a genuine spatial one:

there is exactly one way the plumbing fits.

Every level is proven, not guessed

Each board is machine-verified before it ships. Not merely solvable —

provably impossible to finish while leaving a cell dry, and every pipe

in the solution takes the tightest route its neighbours allow. No filler

detours, no routing that exists only to soak up space. If a pipe winds,

something forces it to.

Glass and liquid

Translucent glass tubing on a near-black board, colored fluid with a real

meniscus, chrome-ringed wells, and a surge of light down the pipe the

moment a flow completes. Built to be read at a glance on a phone in one

hand.

Something to play every day

Seven packs from gentle 5×5 boards up to 10×10 master works, plus The

Mixer — a pack where two colors pour into a hub and a third flows out.

A fresh Daily Puzzle every day with a streak to keep, and a Time Trial

that hands you five more seconds for every board you clear.
