Antiknights, Antipalindromes, and Antisandwiches
(Published on 28. October 2020, 01:28 by UnnamedSorcerer)
Normal Sudoku rules apply. A digit cannot be placed in a cell that is within a Knight's move (in chess) of that same digit. Digits along gray lines do
not form palindromes. Numbers in the upper left of cages indicate the sum of the digits contained within the cage. Digits may not repeat within cages. Clues outside the grid show the sum of the digits
outside the X and the Y in that row/column, where X and Y are consistent for the whole puzzle.
Example: if X = 1 and Y = 9, then the antisandwich is 20, the sum of the green cells.
In f-puzzles, please note that two separate antipalindromes meet in r6c5; they are not one continuous antipalindrome.
