Normal sudoku rules apply.
Identical digits must not touch (i.e. must not appear a chess king's move apart).
Clues outside the grid show the sum of all digits along the indicated diagonal.
Digits separated by a white dot must be consecutive. Not all dots are given.
Solution code: row 1

Puzzle actually looks more intimidating for a 3/5 diff, but I enjoyed the aha moment after discovering the opening secret and then other interesting things :)
