Rules of Pipelink:

  1. Draw a loop through the centers of all cells.
  2. Two perpendicular line segments may intersect (cross) each other, but not turn at their intersection or otherwise overlap.
  3. Clues show how the loop crosses through the cell it’s in.

This is the first time I set a Pipelink. I tried to draw a cat, a tribute to the person who introduced and guided me about the genre, jkittykitkat, :3

The standard Pipelink rules apply.

  • $\begingroup$ @Stevo There is only 1 long pipe that can cross. The second rule states that if the pipe is crossing, both segments must be straight. $\endgroup$

This is a very nice puzzle made by:

athin solution

This is the solve process:

First draw some necessary connections and impossibilities:

step 1

Fill in the top left corner, and some necessary connections:

step 2

Take some free corner areas:

step 3

Fill in some more necessary connections and corner areas:

step 4

Fill in the top-right corner and flesh out the top and top-right areas:

step 5

Realize that covering the bottom left leaves a square underneath the up-heading line uncovered:

step 6

So cross over it and continue:

step 7

See that going up on the right side will either loop prematurely or block the incoming top-loop on the bottom center:

step 8

So go left instead and create a corner that you fill in:

step 9

Finish off the bottom right:

step 10

Fill in some more required connections:

step 11

Fill in some more required connections and deal with corners:

step 12

Prevent looping too early on the top right:

step 13

Use the only out to create a corner:

step 14

Realize the line below the highlighted square can't go down without leaving the line above the highlighted square hanging:

step 15

Fill in some impossibilities:

step 16

Use the created corner and fill in another corner:

step 17

Complete the cross:

step 18

We can try going left at the boxed space, but it forces two separate closed loops to form:

step 19

So, we instead go right and fill in a corner:

step 20

We continue extending on the left side:

step 21

Repeat until we are nearly finished, with only one line remaining:

step 22

Which we promptly fill in:

step 23

The next step is to:

Go celebrate a puzzle well solved :)
