This question is part of the best-puzzle award series.

What are your nominations for the best puzzles, here on Puzzling.SE, of the fourth quarter ( October / November / December) 2020?

Suggested guidelines for nomination:

  • Nominate each individual puzzle in a separate answer, so they can be upvoted/downvoted separately.

  • No more than 3 nominations per person.

  • Don't nominate your own puzzles.

  • Before you nominate a puzzle, check to see if someone else has already nominated it. If they have, then add to that nomination as a comment (or edit it) instead of nominating the same puzzle again.

  • In your nomination, explain what it is that (in your opinion) makes the nominated puzzle such a good one.

Some lists to help jog your memory (your nomination doesn't have to be from these lists):

Algorithmically selected "best of":

Best by votes/views:

Meta-meta issues:

  • Is this kind of thing allowed on SE?

  • What's the point?

  • To highlight and encourage good practice in a way that goes beyond upvotes.

  • To work towards building a 'hall of fame' of some of the best puzzles on the site (perhaps to reside on a future puzzling.SE blog) - think of it as our 'greatest hits album'.

  • To prompt members to put forward their own reflections on what makes a high-quality puzzle.

Another Straightforward 4-letters Crossword? by athin

Everyone knows what a crossword is, yes? I mean, you just solve the clues and put the answers in the grid, right?

WRONG! For me, this puzzle has been one of the highlights of the Fortnightly Topic Challenge so far. This crossword was so unsolvable it took 2 whole days before it fell - and once it did fall (to Deusovi) reading the solution was a real facepalm moment for anybody who usually prides themselves on being an 'outside the box' thinker!

A cunning twist on possibly the best known puzzle type across the globe - a twist I had not seen before, and did not spot this time. Well conceived, cleverly concealed - just very impressive altogether!


Chain Puzzle: Tabletop Games #10 – Risky Finale by Jafe

How much more need I say? This puzzle was amazing, the perfect finish to the first Chain Puzzle series. It somehow managed to incorporate every previous puzzle's answer in an interesting way. Add in a smooth execution and presentation, and this wonder is most definitely worthy of nomination.


Connect Wall - Grid Puzzles Edition! by athin

I really, really enjoyed this puzzle. It included 16 different logic grid puzzles in a Connect Wall...peak PSE! It didn't get as much love as I felt it should have during the FTC, so hopefully this will bring it some more attention.


Graylocke's Rotting Marble Box by Graylocke

This one is a giant contraption full of interesting mechanics. I appreciate the work involved to design one that looks very complicated at first glance but hides a nice property (and also to produce the graphic).
