Mini-Colossal Octoquadri III: Sukoro
Part of a greater collaboration with MaizeGator, in which we are setting pencil puzzle octoquadri hybrids in the "colossal sudoku" format.
Puzzles in our series so far:
Mini-Colossal Octoquadri I: Loop 12 (MaizeGator).
Mini-Colossal Octoquadri II: U-Bahn (sfushidahardy).
Mini-Colossal Octoquadri III: Sukoro (sfushidahardy).
- Mega-Sukoro: Place a digit from 1 through 4 into some of the cells of the 12x12 grid. Some digits are given. Each digit is equal to the number of (up to four) orthogonally adjacent cells that also contain a digit. Identical digits cannot be orthogonally adjacent. All digits form an orthogonally contiguous area.
- Octoquadri + Mini-Sukoro: Place 8 of the digits from 1 through 9 in the 4x4 grid, so that every digit occurs twice, and there are no repeats in any row, column, or box. Place the remaining digit in the "Leftover" cell. Additionally, any digits from 1 through 4 are equal to the number of (up to four) orthogonally adjacent cells that also contain a digit from 1 through 4, and all such digits form an orthogonally contiguous area.
- Interaction: Each cell in the Octoquadri grid corresponds to a 3x3 box in the 12x12 Sukoro grid. A digit N in an Octoquadri cell indicates that there are N digits in the corresponding 3x3 box.
I hope you enjoy the puzzle!
A partially resolved example grid to demonstrate the rules.
Solution code: The cells in row five (from left to right) with an X for empty cells.

Great puzzle. Some fun global deductions, some fun interaction logic, a good amount of time spent between two grids... very well designed! A more approachable puzzle than some of your recent entries but no less dazzling. Very fun. Thank you!

At first it seemed way too underconstrained. Toward the end it was a rush of forced moves that would surely break it unless by some miracle everything fit together just right. I assigned a difficulty of 5. Maybe it’s not that hard, but it was just so unfamiliar and mind-expanding.

I mean...goddamn, that was amazing. More people need to try this puzzle. Simple rules for this sort of thing, yet felt completely fresh and original. And I yelled out loud at realizing a few things along the way. Thank you for somehow making this!

How ??! Honestly, how doesn't this break ? Cool concept and amazing that a valid grid exists at all. Thanks :)

Amazing that this exists at all, and more amazing still how smoothly and gorgeously it unfolds. Thank you for this brilliancy!
