There are already some walkthroughs for the second examples of Rhombitrihexagonal Yagit (I assume that's what you mean by the fence puzzle) and of Killer Tetrakis Square. For Yagit, most of the trick is to draw walls between different symbols, extend walls to reach black points or the edge, and mark edges that can't be walls. For the Killer... well, I didn't try them either (I didn't progress much for the first puzzle), but most of the tricks are based on Killer Sudoku, with occasional deductions from "no identically oriented triangles have the same number" rule.

Thanks, and don't give up! This selection is somewhat more difficult than the introductions on my blog, which you might find to be a more casual environment.

Thanks for the great contest! I liked the variety, especially the nice strategy in Chocona. For me, though, I thought there was too much of a gap between the smaller (easier) and larger (harder) puzzles. I guessed-and-checked a lot on the easier puzzles (Trapezoids and Snake) and barely got to any of the harder puzzles. Maybe that's just me :P

This was a nicely constructed set, although it in general caused me more probems than I would have hoped. I didn't really prepare so had to make sure of the rules while solving a lot because I had to make sure of the adjusted rules. I skipped the most troublesome grids at first (Yagit and Tree). The Tree turned out to be my favourite type though. It worked really well with the genre.
I thought the Yagit would cause me the most problems and I proved myself right (unfortunately). There were a lot of rules that made it hard for me to know what to really be looking for. I made an error in the small one, but managed to fix that when I saw a bad deduction in the resolve. But it was a struggle to get through. I gave the larger puzzle a go in the last minutes but couldn't really make any progress. I think I'm still missing some logical tools to get those started. I'll get to it at a later time.

I'm not sure if these are too hard or just too different. I still don't even understnad the yagit variant.

Congratulations to Endo Ken, Robert Vollmert, and Tomoya Kimura for your incredible solve times. It took me . and thank you so much to everyone who participated. Thank you especially to Prasanna Seshadri, Tiit Vunk, and Deb Mohanty for all your work testing and administrating.

This is certainly not the end of puzzles on non-rectangular grids! There are a lot more ideas in the works and an entire frontier of unexplored tilings. All of these puzzles were designed in several tiny gridded sketchbooks that I made and brought with me on the long bus rides to and from my internship at an architecture firm this summer. Here are two of the four process pages for Truncated Square Chocona 2:



Anne Tyng was an architect and educator who collaborated with Louis Kahn in several projects that explored non-rectangular tilings, including the Yale University Art Gallery, a prospective City Tower for Philadelphia, and early schemes for the Erdman Hall Dormitory and the Trenton Jewish Community Center (pictured below). Tyng was one of many architects in the early 20th century who referenced D'Arcy Thompson's On Growth and Form, chapters 7 and 8 of which illustrate cell aggregation and packing.



Paramesis is a portmanteau of parametric mimesis, a phrase I started using in 2013 to describe an intersection between parametric modeling, architecture, and biology, before I knew that a widely accepted term, for what I was thinking about already exists. The outer circle of the logo represents a genuine attempt to devise a puzzle that would have been called "meristem" and played on a randomized voronoi grid. The objective would have had something to do with auxin gradients, perhaps as some kind of Bossa Nova variant. This attempt eluded me because at corners where four or more cells meet, it can be very difficult to determine whether two cells share an edge or a vertex. Some kind of order was needed.

Thank you everyone for your feedback.
