Pipe Online Game

Pipe puzzle rules

• Connect each pair of same-colored dots with a line.
• The level is clear once every pair is connected. Empty cells can stay empty.
• Lines cannot cross.

Those three lines are the whole game. A finished color is a path that starts on one of its dots and ends on the other. After that, leave it alone and work on the next pair. Paths may run side by side, even in the next row or column. They may not share a cell, and they may not jump over each other.

You do not have to cover the grid. Empty cells are a normal result, not a miss. Use a cell only when some pair needs it as part of its path. Filling the rest of the board does not change a clear you already have.

If a path goes the wrong way, press a cell on that same path and the open end jumps back to the cell you pressed. Undo steps back one change. Restart clears the board when the knot is not worth untangling. Stars, best time, and best move count stay in this browser.

How to play the pipe online game

1. Press a colored endpoint and drag toward its matching dot.
2. Move only up, down, left, or right. A diagonal is two steps, and both cells have to be free.
3. Release on an empty cell if you want to stop. Pick the open end up again on the next drag.
4. Use Hint to light up to three guide cells, in order, or Undo to step back.

You can also start a drag on a cell that already belongs to a path, which continues that color from the nearer end. A bare press on an endpoint starts that color over. The hint button stops after three uses on that attempt. It marks a route; it does not draw the line for you, and it does not reveal the other colors.

Hide time if the clock is a distraction. The clock still runs, and the star rating still uses it. Share copies your time, your move count, and a link that opens this same level. The skin button switches between round dots and a pipe look with square ends and a thicker line. The rules do not change.

How this pipe online game differs from Pipe Mania and Flow Free

Pipe Mania, and the puzzle many people met as Pipe Dream, is a different game. You rotate tiles so a stream can get from a starting pipe to the other openings before the water catches up. The pressure is a countdown. PipeTrio does not hand you tiles to spin, and nothing floods the grid while you think. The clock here only records how long the level has been open. You can hide the digits. You cannot lose by being slow.

Flow Free made the colored-dot board familiar: pair every color, and the usual aim is one cover that fills every cell. PipeTrio keeps the picture — two ends of a color, a line that cannot cross — and stops at the pairs. When every matching pair is joined, the level is complete even if some cells are still blank. You are not hunting a perfect tiling. A short, direct connection is a valid finish for that color.

That changes the early moves. In a fill-the-board puzzle, a short link can be a mistake because those cells were reserved as a corridor for a longer color. Here a short link is often the right first move. Cells you never touch are simply unused. What still matters is the local problem: do not lay one path across the only route another pair can take.

If you searched for a pipe online game, you can start from the board above without a second rule set. If you came from a pipes-and-water game, expect drawing instead of rotating, and no stream to race.

Board sizes from 5×5 to 13×13

5×5 pipe puzzles are the place to learn. These boards use 3 or 4 colors and 25 cells. You can see every end at once, which is why this page starts here. A few of them on a phone, one hand on the screen, are enough to make the drag feel obvious.

7×7 pipe puzzles use 5 or 6 colors. The board is still one sitting, but a color is no longer solved by a single glance. Open this pack when 5×5 feels short and you want a normal puzzle rather than a lesson.

10×10 pipe puzzles use 12 to 16 colors. You are tracking many pairs. The useful habit is to join a pair that is already close, then look for a pair whose only corridor is about to be cut off.

13×13 pipe puzzles are the largest grid, 169 cells, shared by many pairs. Paths are often short. The work is sorting colors, not drawing one maze across the whole board. It suits a longer session at a desk. On a small phone the dots are smaller, because the grid scales to the screen, so 7×7 is the kinder phone size.

Each pack holds 100 levels. The stars on a card are a difficulty mark inside that size, from one to five. A one-star 13×13 is an easier level of the large size, not a claim that it is the hardest board on the site. A five-star 5×5 can ask for more care than an easy board of the next size.

From the last level of a pack, Next sends you to the first board of the next size and shows a note to try a larger board. The 13×13 pack stays inside itself and returns to its first level.

What to do when a color will not connect

Connect the short pairs first. If two ends of one color are already neighbors, join them before you draw anything else. That path uses few cells and removes a color from the board. Pairs that sit far apart still have room to route around the short ones.

Then look at edges and corners. A corner cell has only two neighbors. If one color needs that corner and another path takes it first, you may have to undo a long stretch. When an end sits in a corner, deal with that color before you park a different line on the corner's only exits.

Do not treat a diagonal as a step. If the matching dot is one row down and one column over, the path needs two orthogonal steps, and both of those cells have to be free. Empty cells may stay empty only when no remaining pair needs them. If they are the only corridor, use them.

When the line will not enter a blank cell, that cell is usually not a side neighbor of the current end, or another color already owns it. Drag through the free cells that do touch the end. You can also press a cell on your own path to retract to that point and leave by a different neighbor.

If you are stuck, use one hint. It marks the next cells of a working route, in order, not a random cell. Follow those marks, then finish the pair yourself. Undo is for the move you regret. Restart is for a board that has become a knot. Once every pair is connected, stop. Covering the leftover cells does not make the clear more complete.

Pipe online game FAQ

Do I need to download an app?

No. PipeTrio is a pipe online game in the browser. Open the page and the first board is ready. The same page works on a phone and on a desktop. There is no store listing to install.

When is a level solved?

When every pair of matching dots is connected by one line. You do not have to fill every cell. Empty cells can remain. A pair counts as connected when the path starts on one of its dots and ends on the other.

Is my progress saved?

Stars, best time, and best move count are stored in this browser. Refresh the page and the solved marks are still there. Clearing site data, or switching browsers, starts that record over. There is no account to sync it.

Can lines cross or share a cell?

No. A cell belongs to one color. Paths may run side by side, including along the next row or column, but they cannot occupy the same cell and they cannot jump over each other. A blocked move flashes so you can see which cell refused the line.

Do I have to fill the whole board?

No. Connecting every pair is the clear. Covering every cell is not required. This is the rule on every size, from the 5×5 boards on this page through the 13×13 pack.

What do the four board sizes change?

The grid gets larger and the number of colors goes up: 3 or 4 colors on 5×5, 5 or 6 on 7×7, and 12 to 16 on 10×10. The 13×13 pack is the 169-cell board, with many short pairs. The rules stay the same. Each size has 100 levels. Start on 5×5 if you are new.

How do hints work?

A hint lights the next cells of one working route, in order, up to three cells. It does not draw the path and it does not reveal every color. Each attempt allows three hints. Restarting the level gives you the hints again.

Can I undo a bad line?

Yes. Undo steps back one change, and Redo puts it back. You can also press a cell that is already on your path to retract the end to that cell. Restart clears the whole board when you want to begin the level again.

Does it work on a phone?

Yes. Drag with one finger. The grid scales to the width of the page, so you do not scroll sideways to see the board. On a small screen, 5×5 and 7×7 keep the dots easier to hit than 13×13.

Is PipeTrio free?

Yes. Every level on the site is free to play in the browser. You do not sign in, and you do not pay to open the next size.
