Squished Doughnut

(Published on 24. September 2024, 11:00 by ThePedallingPianist)

My cruel, cruel brain decided that, despite being the father of a baby in a sleep regression, it was worth staying up an extra hour to explore the ludicrous concept of Toroidal Squishdoku. You'll be glad to know that it doesn't work on squished "9x9" or "6x6" grids, but when I found that a squished "8x8" grid worked, I had to pass on my brain's cruelty by inflicting this utter nonsense on the sudoku community. My apologies.

Play on SudokuPad



Toroidal Squishdoku: Fill every cell with a digit from 1-8 such that digits do not repeat in a row, column or 4x2 box. There are eight boxes, which overlap at dashed lines, and some boxes wrap around the grid, which is a torus. For example, r1c6 and r4c2 share a box.

Dutch Whispers: Adjacent digits on an orange line must differ by at least 4.

V: Digits separated by a V must sum to 5.

Solution code: The sum of all digits on the orange line

Started off utterly, utterly perplexing, but then once you figure out the trick it all falls into place and almost solves itself.

Incredible puzzle, you can't help but grin as you finish it.

Very intimidating, but then it all falls into place as soon as you figure out how to get started. Lovely puzzle!

The truly mind-bending part of this puzzle is how utterly approachable it turned out to be. Incredible!

That is unbelievably good, really enjoyed that. Could arguably be a 1 star difficulty, but not with that ruleset haha.

This is exactly what I've come to expect and adore about a ThePedallingPianist puzzle!

This was amazing! Such a simple idea, executed in the most elegant way possible. The shape of the Dutch Whisper line could not have been a more perfect choice for resolving the digits in a slick, clean, but non-trivial way. Standing ovation for this one
