2024 con un drum (Sudoku)
(Published on 5. January 2024, 17:19 by glum_hippo)
Normal Sudoku rules apply. Each row, column, and 3x3 outlined box contains the digits 1-9 once each.
Digits separated by a white dot are consecutive.
Digits in cages must add to 42, without repeats. Furthermore, each cage can be divided into 3 sub-cages whose cells are connected orthogonally, i.e., via shared edges. The 3 subcages can be in any configuration and size (one or more cells each), but they must have sums of 8, 11, and 23, respectively. For example, a cage can hold subcages consisting of 8, 245, and 1679; or 125, 47, and 689, etc.
Also, 8x11x23 = 2024, ergo happy new year!)
Solvable in F-puzzles or in SudokuPad.
Solution code: Row 9 (9 digits total).

Great puzzle, interesting pieces of logic, didn't find it too difficult compared to other 4 stars in here

What a beautiful multilayered puzzle. It took me quite a while to get going, with tentative colorings and whittlings down of possibilities --- and then when I realized how the shapes and sums interacted, it started to fall into place. Really fantastic!

Fantastic puzzle! Needed a bit of combinatorial prep work, but after that it was super smooth sailing. Very rewarding!

Very satisfying solve. I, too, broke the puzzle a couple of times, making erroneous "deductions" about the sub-cages. But the joy of solving this ultimately won out. Brilliant construction!

This was a very fun and rewarding solve. Admittedly took me breaking the puzzle a couple of times before it finally clicked, but it was well worth the effort. The sub-cages constraint adds some really interesting logic throughout the entire puzzle.

Toll! Ich hab keine Ahnung, ob ich diese Kannohne- oder Kannmit-Trommel an zu lösen fangen werde, aber ich finde das Rätsel jetzt schon super :) .
