E_ca_ation 3: The Battlefield
(Published on 8. August 2021, 07:04 by SSG)
Normal sudoku rules apply.
Antiknight: Cells separated by a chess knight's move may not contain the same digit.
Battlefield (based on Big Tiger's rules): The digits in the cells at either end of each row or column represent the distance an army advanced into the row or column from that direction. The clues outside the grid are the sums of the cells within the corresponding row or column that are traversed by either both armies or neither army, whichever applies.
XV: Pairs of cells connected by an X must sum to 10. Pairs connected by a V must sum to 5. If all XV clues were given, they would form a single linked group of cells (i.e. each cell in the group connects to every other cell by some chain of Xs and Vs), representing the location of the archive.

Took me quite a while to grasp the full extend of the XV chain's implications.

Scanned the battlefield for the archives on my own but luckily remembered in time to ask the anti-knight-movement to assist in the search.
nice puzzle. thanks.

Tip: unless familiar with this ruleset do look at the linked puzzle first

Does "linked group" have to be linked orthogonally or can it be diagonally as well?
-What links the group of cells together are the XVs. So, diagonally adjacent cells can be part of the group only if linked by way of other cells. -SSG
