Drag pipes between matching coloured dots on a five-by-five grid. Lines cannot cross — link every pair to clear the puzzle.
Keyboard works too Everything runs inside your browser. Nothing is installed on your phone.
Controls
Drag from a dot to its twin. Lines cannot cross or overlap. Connect all four pairs.
How to play
- Start with the pair that looks most blocked — it has the fewest route options.
- Drag from a dot, tracing one cell at a time.
- Pull back along your own line to shorten or erase it.
- Run colours along the outer edges before filling the middle.
- Connect all four pairs without any crossing to win.
About this game
Color Flow takes the flow-puzzle formula and keeps it at the perfect snack size: a five-by-five grid, four pairs of coloured dots, and one rule that does all the heavy lifting — pipes cannot cross each other. Drag from one dot to its twin, watch the line follow your finger cell by cell, and fill the board without tangling any two colours together.
The drag controls are built for thumbs: start on a dot or anywhere along an existing pipe to redraw it, trace a path one cell at a time, and pull backwards along your own line to erase it. Releasing the finger keeps the pipe in place, so you can plan one colour at a time. The moment all four pairs connect, the board lights up and your move count is compared with your personal best.
Several hand-designed layouts rotate at random, each solvable in multiple ways, so repeated boards never feel repeated. The strategy that separates beginners from fast solvers is edge discipline: the border cells are the most contested real estate on the board, so running two colours along opposite edges first leaves the chaotic middle free for the last pair.
It is a genuinely calming game — no timer, no fail state, just you, four colours and a grid that always has an answer. Perfect for a lift ride or the last five minutes before sleep.
Frequently asked questions
Do I have to fill every cell?
No. Only connecting each pair matters, so elegant solutions that use fewer cells count just as much.
How many layouts are there?
Five hand-designed five-by-five layouts rotate randomly, each with multiple valid solutions.
What does the Best counter track?
It records the fewest total cells you have placed across a completed board — a tidiness score.
Can two pipes share a cell briefly?
No. Overlaps are rejected as you drag, which is what makes the routing puzzle interesting.
