Anti-Knight Anti-King Quadruples
(Published on 12. July 2025, 17:43 by snoswal)
Normal sudoku rules apply. Each row, column and 3x3 box contains the digits 1 to 9.
Anti-Knight. Cells a knights move (in chess; a 2x1 "L") apart cannot contain the same digit.
Anti-King. Cells a kings move (in chess; immediately adjacent including diagonal) apart cannot contain the same digit.
Quadruples. Digits in circles must appear in the four surrounding cells.
