2025 Chaotic X-Sums (8x8)
(Published on 15. January 2025, 19:04 by Florian Wortmann)
Chaos Construction
Divide the grid into regions, each consisting of eight orthogonally connected cells. Each row, column and region contains the digits 1-8 once each.
X-Sums
A clue outside the grid is the sum of the first X cells in the corresponding row/column, where X is the digit in the cell nearest to the clue.
In addition, in every row/column with a clue, the first X cells are in the same region, and the X+1th cell is in a different region.
The ?-clue also has this region building property but the sum is unknown.
