Place a digit from 1-9 into every cell of the grid so that each digit appears exactly once in every row, column and outlined 3x3 box.
Cells that are a king's move apart must not contain the same digit - in other words, cells that are diagonally adjacent cannot contain the same digit.
Solution code: Row 1, Row 9

So it is equal to a „No Touch Sudoku“. In Sudoku GP 2017 round 5, we had also a variant with Chess Kings, where two numbers represented the two kings.
