Is Néon Flow free to play?

Yes. Néon Flow is completely free and runs straight in your browser — no download, no install, no paywall.

How do you play Néon Flow?

Hit “Play” to start Néon Flow. It runs on keyboard on desktop and on touch controls on phones and tablets — no controller needed.

Do I need an account to play?

No — you can play right away as a guest, and your best score is kept on this device. A free account (by email link, no password) syncs your high scores, puts you on the leaderboards and unlocks trophies.

Does Néon Flow work on mobile?

Yes. The game is responsive and fully playable with your fingers on phones and tablets, just like on desktop, with no app to install.

Do I really have to fill every cell, or just link the dots?

Both are required. Linking every colour pair is necessary but not sufficient: while a single cell is still empty, the level does not validate. That double constraint is what makes the solution unique and the puzzle interesting.

How does the timer work in Néon Flow?

You start with 45 seconds, and every level you solve adds 12 seconds back, up to a 90-second ceiling. The grids grow from five cells a side up to eight with more flows to untangle, so a big level eventually costs more time than it returns — which is what keeps the run tense and finite.

What happens if my pipe runs over an existing path?

If it is your own pipe, you retract it by going backwards. If it belongs to another colour, your crossing wipes that pipe from the point you cut it, and you will have to retrace it — so it pays to plan around collisions rather than through them.

Néon Flow

Against the clock: link the colour pairs by drawing neon pipes with a finger, without crossing, until the grid is full. Every level solved buys time. Chain as many as you can before the clock runs out.

About this game

Néon Flow is a connection puzzle played AGAINST THE CLOCK in a polished retro-neon skin, in the line of the great pipe and flow games that won over millions of mobile players, reworked with a bright modern look and a feel built for 60 frames per second. On a square grid, pairs of coloured dots wait to be joined. For each colour, trace a glowing pipe linking its two ends by dragging your finger from cell to cell, horizontally or vertically only. The golden rule: pipes cannot cross, and a level is only solved when EVERY pair is linked AND EVERY cell of the grid is covered by a pipe. That double objective — link it all AND fill it all — turns simple tracing into a real puzzle of order and foresight: you will often have to undo one path to make room for another. Drawing is completely fluid and touch-first: put a finger on a coloured dot and slide along the cells to unroll the pipe; go back over your own path to retract it; cross another colour and you wipe it from the point you cut in, leaving you to rebuild it. With a mouse it works exactly the same. Every pair linked sets off a flash of light and a soft synthesised cue, and completing the grid releases a satisfying neon wave — plus a precious time bonus — before moving AUTOMATICALLY on to the next level. Because everything here is a race against the clock: the run starts with forty-five seconds on the counter, and every level solved hands time back. Chain them quickly and you survive; hesitate and the countdown catches you. The difficulty climbs without let-up: you begin on small grids five cells a side with a few colours, then the grid grows to eight cells a side and the number of flows rises, until a big level ends up costing more time than it returns — the run always stays finite, tense and rewarding. Every generated level is guaranteed solvable by construction. Your score is the number of levels you solve before time runs out: the more you chain, the higher you climb. To stay readable with colour blindness, each colour also carries a distinct shape on its endpoints (circle, square, triangle, diamond and so on). Néon Flow is free and instant in your browser, nothing to install, on desktop and mobile alike. Create an account to sync your high scores, enter the leaderboards and unlock trophies as you flow. How far will you get?

How to play

Link each pair of matching dots with a pipe and fill the whole grid, without letting any two pipes cross — against the clock.

Game rules

The grid holds several pairs of coloured dots: for each colour, trace a pipe joining its two ends.
Drag from cell to cell, horizontally or vertically only — never diagonally — to unroll the pipe from a dot.
Pipes cannot cross: running through a pipe of another colour wipes that one from the point you cut it.
Retrace your own path backwards to retract it if you change your mind, without starting over.
A level is solved when every pair is linked AND every cell of the grid is covered by a pipe: two conditions, not one.
The whole run is a race against the clock: you start with 45 seconds, and every level solved hands some time back before the next one starts automatically.

Controls (keyboard and touch)

Mouse (click and hold, then drag)Trace a pipe from a coloured dot, cell by cell
Finger (continuous drag)Unroll or retract the pipe along the path you want

How a run ends

A level is cleared once every pair is connected and the grid is completely filled, which buys you extra time. The run ends when the clock hits zero — your score is the number of levels you solved before it did.

Tips & strategy

Start from the corners and edges

A dot in a corner has only two ways out, sometimes only one. Beginning with those constrained cells locks in stretches of certain path and cuts the number of combinations to explore enormously.

Never forget to fill everything

Linking the pairs is not enough: every cell has to be covered. If one is left empty, a pipe has to detour to reach it, usually by hugging the edge instead of cutting straight across.

Speed is the score

The clock is what ends the run, so a level solved fast is a level that pays for the next one. On the small early grids, chain them quickly to bank time for the eight-by-eight boards, where a single level can cost more than it gives back.

Did you know?

Linking pairs of dots without crossings while covering the whole surface is an old logic puzzle, sometimes traced to the "Number Link" puzzles published by Japanese houses. It is a cousin of the planar graph problems studied in mathematics.

The genre found massive mobile success with "Flow Free" in 2012, which made finger-drawn connections the norm. Its total-coverage constraint — link AND fill — sets it apart from a simple maze and makes it a genuine exercise in spatial optimisation.
