Classic Sudoku rules are as follow : Each row, column and 3x3 region must contain the digits 1-9 once.
I am certainly not the best at creating classic sudokus, but here is my best try. I'll rate it as 2* but beware that at a certain point you must apply non-trivial logic to finish the puzzle.
You can use Penpa-edit for solving it on your browser.
Solution code: Row 6, followed by column 5.

Not that easy for sure. But nice.

Changed the difficulty to 2 stars due to overall opinion. (Another one will be published at 00:00, it will be easier)
