Three Cubes (3D-Sudoku)
(Published on 2. October 2022, 16:04 by Raumplaner)
Rules
- Normal sudoku rules apply.
- Kropki Pairs: Digits connected by a black dot have a 2:1 ratio. Digits connected by a white dot are consecutive. Not all possible dots are given.
- Cube Construction: Three 3x3x3 cubes are formed by stacking sudoku boxes on top of each other without rotation. When viewed from each of the three directions, the three layers of a cube each contain a full set of the digits 1-9. The three boxes that make a cube must not share the same rows/columns of the 9x9 grid. No box is part of more than one cube.
Examples: The digit in R1C1 must not appear in the top row or left column of its cube's other boxes. The digit in R5C5 must not appear in the center row or center column of its cube's other boxes. Introductory puzzle.
Solution code: Row 5 (from left) and column 6 (from top - 18 digits in total):

I really loved the Würfel concept! I first did not get that every level of one cube has to be from a different row/column but once I realised that is was a nice solve. Would a sudoku without this restriction also be possible?

A very nice sudoku! The introductory puzzle is a must IMO if you are not familliar with the concept.
I enjoyed the way the cubes revealed themselves and even after that the puzzle had more secrets within. 5/5 for fun! :D (3/5 for difficulty)
