福嶋啓之 composed the ruleset and first puzzles of Pipelink (1993), shared at Puzzle Communication Nikoli, 45, alongside many other original paper puzzles. This ruleset is also known as Hyperlink.

In 2024 Pedro released the Pipelink interactive app, leveraging the Kudamono Editor system. Pedro derived the programming logic, decided on colours & input modes and created all graphic assets, by tracing SVG paths. Rule panels by PinkHoodie on 12/06/2024.

All puzzles listed on this page have a single, unique solution. Brand-new puzzles are proudly submitted by their authors regularly, while historic puzzles gain a new life in the interactive Kudamono format: here transcribed for the first time, with permission from each author, on a unit-, genre- or general basis.

Start with a blank page (new Pipelink puzzle).

Detailed editing instructions and shortcuts can be found at the manual.

The following variants are suggested: ice and hex.

For more information about global variants, and how to combine multiple variants in a single puzzle, please see the variants page.

The following custom insertion shortcuts apply to Pipelink:

Keyboard shortcuts for Pipelink (S = solving, E = editing, S/E = both solving and editing )
Glyph When Submode Shortcut Description
www.w3.org/2000/svg'> S—-A → Uauto mode: auto-choose submode based on gesture type and location
www.w3.org/2000/svg'> SlineL → Iline (solve): drag or click to draw definitive line (solve)
www.w3.org/2000/svg'> EsymbolXAbsent tile: click or drag to place definitive symbol Absent tile
www.w3.org/2000/svg'> EsymbolP → Ipipe(s): click or drag to place definitive symbol pipe(s)
www.w3.org/2000/svg'> S/Eaux markXcross: click or drag to place auxiliary cross
www.w3.org/2000/svg'> S/Eaux lineS → Ksketch line: drag or click to sketch auxiliary line

Pressing an exclusive editing shortcut while solving, or vice-versa, causes a switch into that context. In contrast, shared shortcuts cause no switch, but are instead chosen to match the current context.

Please with any issues and suggestions.

There are specific instructions for live conflict highlighting and input issues, for improving the rule panels or reporting non-uniquenesses.

For any other bugs, please:

  • describe what you were trying to do,
  • what happened instead, and
  • send the current url (plus any visible error logs and possibly, supplementary screenshots).

You may check whether your bug is already covered by the unit tests (it may take a few seconds before the page loads fully). Any yellow boxes indicate a failed test. "Performance issues" currently indicate all passed tests, slow or not.

If you find a situation where the live conflict highlighter is not working as you'd expect (e.g. too aggressive, incorrect), please send a small test case url plus a brief explanation of what should be happening instead.

A good test case includes the smallest possible board, with the fewest possible elements, that is still able to unambiguously reproduce the issue.

For interface issues related input modes, or more generally to clicking/touching/dragging, keyboard shortcuts, etc… please submit an input test case, as detailed in the Inputs Initiative.

For simple typos/rewordings, a short email suffices. For more substantial changes, please refer to the rule panels guidelines.

If you find a non-uniqueness in one of the puzzles, please first check whether you are able to contact the puzzle author directly to request a fix.

If that seems impractical, please submit either:

  • a corrected, unique puzzle url (with solution), if you are able to suggest a fix (preferred); or
  • a puzzle url solved up to the point where the puzzle stops being unique; or
  • multiple urls (one per solution)
