Today's GAPP is a Shape Loop (シェイプループ)! I hope the very long 101 spoiler doesn't scare you. I recommend trying it out without the 101, and only checking it if you're stuck.

Rules: Draw either a right triangle or a square in some cells, such that when connected they form a single loop where each shape must connect to exactly two others. Some cells are already given. The loop must not turn at square cells.

GAPP 101
Here's an alternate ruleset that may be easier to reason about:

Draw a non-intersecting loop that travels orthogonally through all cells with clues. Cells with a square clue (fully shaded) must be passed straight through, while cells with triangle clues must be passed by the loop through the two sides that touch the edge of the cell. There must not be two orthogonally adjacent cells with disconnected, parallel straight line segments.

Mind the GAPP vol. 55

We have a very special announcement this month: There is now an official GAPP website!

The website contains the entire backlog of GAPP. It is intended for people who want to solve GAPP but don't want to create a Discord account or join a new server. We've tried to make the experience as close as possible to the Discord server. You can visit the website here: https://gapp-puzzles.com

This server still remains the main platform of GAPP. It is where puzzles go up first, and where discussions happen. There is a one-week delay from when puzzles are posted in the server to when they go live on the website.

Finally, we have six bonus puzzles this time, and for some reason four of them are Nurimisaki. Enjoy!
