RULES

Sudoku: Normal sudoku rules apply.

Indexing: Digits in column 1 indicate the column in which the digit 1 appears in its row (e.g. if r5c1 is a 3, r5c3 is a 1). Digits in column 9 do the same for the digit 9.

Digits in row 1 indicate the row in which the digit 1 appears in its column (e.g. if r1c5 is a 3, r3c5 is a 1). Digits in row 9 do the same for the digit 9.

Quadruples: Digits in a circle must appear at least once in the surrounding four cells.

Anti-King:Identical digits may not be a chess-king's-move apart.
