- Normal Standard Sudoku rules apply.
- Outlined regions are cages. The sum of digits in a cage is given in the top-left and digits cannot repeat.
- Clues outside the grid show the Sum of all the digits along their respective diagonals. Digits can repeat along these diagonals if allowed by other rules.
- R4C5 is higher than R4C6.

Joseph, a colleague and longtime friend from our university days, challenged me to solve the hardest Sudoku puzzle he’s ever created—and gave me a whole year to crack it. Guess what? I managed to solve it in just 5 months! It was insanely tough, but major props to him for crafting such a brilliant challenge!
@Hadi A2wa Dj bel 3alam. Khayye. Thank you bro for solving it and am extremely impressed and proud of you for doing so.

It was pretty easy at least to get one digit in the grid. Then it became pretty much harder :-) Ended up with a very pretty and colourful grid until I could use the little killers. Very nice! Thanks a lot for a fun killer :-)
@Godrick Thank you :)

Wow, super intricate, great construction! 5/5 difficulty imo.
@Vebby Thank you my friend:)

Holy moly. This one had a fun start and became increasingly difficult. The use of the last two clues was mind-bending. Thanks!
Meine Güte. Es ging ganz nett los, wurde aber zunehmend schwieriger. Die Nutzung der beiden letzten Hinweise hat mich fast um den Verstand gebracht. Aber nur fast. Danke!
@Tilberg Thank you :)

Good grief, what a stunning construction with consistent difficulty throughout!
I had to divide the solve into multiple mini stages, but each of them unfolded its magics wonderfully and I had a great smile when LKs came into play ;)
@Playmaker6174 Thank you my friend :)
