My first Nikoli puzzle book was Pencil Puzzle Yajilin 1, back in 2006 when the Pencil Puzzle series was available. Yajilin has always been a special puzzle type for me. It marks the beginning of that unscratchable itch that I think most puzzlers have, to relentlessly explore new puzzle types and variations and to engage with problems for which no well-trodden inventory of techniques already exists. I’m happy to return from my break with a Yajilin variation on a new tiling [33434; 3262; 3446; 63].
EDIT: Following a suggestion from edderiofer, I have made the clue cells easier to distinguish.
EDIT 2: Puzzle number 3 has been corrected. The far right hexagonal clue should have been a 3.
Rules
Shade some cells and draw a loop in remaining cells such that:
- Every empty cell is either shaded or part of a single loop that does not branch or intersect.
- Numbers in some cells indicate the total number of shaded cells that can be seen in all directions from that cell. Lines of sight run perpendicular to the edges of a cell and terminate on the edge of the grid or at a triangular cell, counting that cell.

Hi, thanks for the great puzzles!
I think that there is a mistake on puzzle 3. My hypothesis is that the rightmost 2 was supposed to be a 3.

I’ve finally tested and corrected this. You are correct, it was originally a 3 in my notebook and somehow I didn’t catch the error during print tests. Thank you.
