Rules:
Normal Sudoku rules apply. Cells separated by a Chess knight's move must contain different digits. Cells surrounded by a white circle must contain the digits in the circle exactly once. The grey square contains an even digit.
If I could, I would give this puzzle 6/5 for difficulty.

Brutal puzzle and I think it deserves a 6/5 for difficulty !

A continuous process of scanning and testing. Extremely difficult but after making the right decisions, the puzzle becomes much easier.
