Play on SudokuPad
Normal sudoku rules apply.
A cell is 'friendly' if it contains its row, column, or 3x3 box number. Boxes are numbered in normal reading order. I.e. the R5C1 cell is friendly if its digit is 1, 4 or 5.
Friendly cells must see at least one cell a knight's move away that contains the same digit.
Digits on an arrow sum to the digit in its circle.
Friendly cells on an arrow or circle count as 0 for the sum of that arrow.
Solution code: row 2
