Connect matching colors and fill every cell with pipes
About Pipe Connect
Pipe Connect is a flow-based logic puzzle where you draw color-coded pipes between matching endpoints to fill every cell on the grid — no gaps, no crossings. Inspired by the classic Flow Free format, it scales from gentle 5x5 beginner grids to demanding 10x10+ boards with optional time limits. Play pipe connect online free and discover why millions find it impossible to put down.
How to Play
Click and drag from any colored dot to its matching dot of the same color to draw a pipe. Every single cell on the board must be covered when you are done — leaving even one cell empty is not a valid solution. If two paths conflict, redraw one of them. Solve without hints for a perfect score, and beat the par-move count to earn bonus points.
Tips & Strategies
- Connect the most constrained colors first — dots tucked into corners or close together have very few valid paths, so solving them pins down the grid and guides all other routes.
- Work from the edges inward: border and corner cells have at most two entry/exit directions, making their correct path far easier to deduce than interior cells.
- If a long path must traverse most of the board, lay it down before the shorter paths — it acts as a spine and the remaining routes fill the gaps naturally.
- Whenever you spot an isolated empty cell surrounded on three sides by filled cells, the one open neighbor must route its pipe through it — use this constraint to force correct paths.
- Use the Undo button freely; Pipe Connect rewards methodical backtracking, and un-drawing one wrong pipe often unlocks the entire solution.
