Sunday update with solutions

Later today we’ll be adding Yajilin-Battleships by Serkan Yürekli to our e-store and we’ll have another title next weekend as we begin publishing more books on our site.

Our most recent week of Cave puzzles can be found in this PDF and the solutions are all grouped in this PDF and have also been linked to the individual posts.

We have a solving video for three of this past week’s puzzles. First is a solving video focused on an important heuristic for Cave puzzles, which was quite useful for the Tuesday Cave by Serkan Yürekli:

We also have a video for the Friday “Singularity” Cave by William Hu:

and a video for my “Antisymmetry” Cave:

This upcoming week will feature Balance Loop puzzles including a couple variations.
