Top Right Boi
(Published on 21. June 2025, 12:00 by DubiousMobius)
Chaos Construction Sudoku: Create 9 orthogonally connected 9-cell regions. Digits may not repeat in any row, column, or region. The cell edges with thicker black lines are provided region borders, and the cells they separate belong to different regions.
TRB Arrows: Long blue Total-Regions-to-Boi Arrows count the number of regions between themselves and the the boi in row 1 column 9 by looking in a straight line in the direction indicated by the arrow. Arrows count both the arrow cell and the boi cell. Each region seen is only counted once, even if it is seen multiple times.
TRB arrows are individual, so If a cell contains 2 arrows, then each arrow will see as many regions as the digit in their cell.
Sightline Arrows: Short red Sightline Arrows count the number of cells they see within their own region in the indicated direction, including the arrow cell. Region borders block vision.
Sightline arrows are cumulative, so if a cell contains more than one arrow, it will contain a digit equal to to the number of cells seen by all the arrows.
Fractal-wrapped grid: The left edge of the grid wraps around to the top third of the right edge of the grid, and the bottom edge of the grid wraps around to the rightmost third of the top edge of the grid. So in column 1, rows 1, 2 and 3 are all adjacent to row 1 column 9. The coloring reflects this. For example, an arrow looking west from 8c1 will look into r3c9 from its eastern edge, still looking west.
Sightline arrows that wrap around the grid traveling east or north will look along ALL the rows and columns that are adjacent to the cell they look from.
Regions may wrap around the grid between cells considered adjacent.

Solution code: Column 8 from top to bottom, with a / separating cells belonging to different regions. E.g.: 123/4567/89

Awesome puzzle, quite mind-bending, impressively set!

wowow. I must've restarted this 3 or 4 times before finally having things click into place for me, over the space of several sessions. Left the tab open to come back to this a while back and I'm really glad I did - and that I stuck with it enough to figure it out~

I was delighted just reading such a bizarre wraparound ruleset. The puzzle itself was even more delightful and satisfying. It felt like a healthy, challenging workout that left me proud and wanting more (rather than some death march that left me relieved to be done with it).

My head is absolutely swimming after that.

This puzzle is awesome and definitely one of the most approachable 5* puzzles I’ve tried

This is definitely a masterpiece! Very fresh and innovative ideas and logics behind! I found it not as hard if you internalize with the ruleset, but solving several arrow puzzles from setters like KNT, gdc and Gliperal are definitely of help here. Very smooth solve path, but it’s quite easy to commit an error, although it becomes promptly obvious and you can’t walk a mile with it, and you counterintuitively adapt the picture on the go. Definitely a brilliant puzzle and it’s quite bizarre how it was compiled in such a fascinating way. Had a smile with the classic form of one of the last regions. Keep it up, DubiousMobius, I’d fancy solving more puzzles from you!

What a puzzle! Very difficult, but feels so rewarding to finish it. For me, while the fractal-wrapped grid was difficult, it was really the amount of arrows that tripped me up (not in a bad way!). Hard to figure out the right place to look, and in several instances I had something obvious staring at me for a while before noticing it. Thanks for setting it!

Seconding what GoodMorningCallum said

What an outrageous puzzle! I genuinely have no idea how you came up with it, but it’s a masterpiece with some truly astonishing logic. It’s brutally hard, and I’d give it 6/5 stars for difficulty if I could. Thanks so much for creating it, I loved it!

This is THE best puzzle I have ever solved.

Rule clarification

The term "moving" is never defined, and I don't know what it means in this puzzle, especially considering the crazy wraparounds.

Sorry for the confusion! I've updated the language to use a metaphor of looking rather than moving. Hopefully that makes more sense. Thanks for asking for clarification, and let me know if I need to clarify further.

Now I have solved all the Top Right Bois, and what a finale this was. Fantastic puzzle DubiousMobius.
