Netslide Pipe Puzzle Unblocked

Netslide Pipe Puzzle takes a pipe network and scrambles it in the most awkward way possible. No tile is rotated; each one already points exactly where it should. They are simply in the wrong places, and you can only fix that by pushing an entire row or column one step at a time, with the tile that falls off one end reappearing at the other. Richard Boulton wrote it for Simon Tatham’s puzzle collection on top of the same generator as the rotating pipe game. Play it unblocked here on small boards that are deceptively tricky.

Arrows Around the Edge

Grey arrows ring the board, one at each end of every row and column. Click one and that line shifts a square in its direction. Right-click, or press and hold, to shift it the other way.

A black tile marks the network’s source. Everything connected to it is drawn in cyan or with a teal pipe. The status bar shows your moves and a count such as “Active: 6/16”. Bring every tile into the network, with no closed loops, and the board flashes with COMPLETED.

Difficulty works differently from most puzzles here:

• Easy boards draw red barriers where pipes cannot cross, which act as strong hints.
• Medium boards take the barriers away.
• Hard boards also wrap, so pipes can run across the outer edges.

Sizes are 3x3, 4x4 and 5x5. Custom lets you change the size, turn wrapping on or off and set the barrier amount.

Moves That Keep Your Progress

Learn on 3x3 Easy. With barriers drawn, you can often work out where most tiles belong before your first move. Use that time to plan.

Build one line, then protect it. Finish the top row first. Afterwards, try to only slide that row as part of a there-and-back move so it ends up where it started.

Use the three-step swap. To move a single tile without wrecking a row: slide its column to bring the tile into a working row, slide that row to line it up, then slide the column back. Everything except the target returns to place.

Count the dead ends. Each dead-end tile must end up plugged into a pipe that leads to the source. If one is stuck facing a barrier or another dead end, it is in the wrong square.

Undo is unlimited. Try a sequence; if it scrambles more than it fixes, step back.

Compared With the Rotating Version

In Net Pipe Puzzle, each click turns one tile, so mistakes stay local. Here, every click touches a whole line, which makes it closer to a sliding block puzzle than a pipe game. If that style appeals, Fifteen Slide is another good test of move ordering.
