Sudoku: Normal Sudoku rules apply.
Dynamic Fog: The grid is partially covered in fog. No Peeking: Digits must be placed in visible cells only. Placing a digit in the last visible cell will reveal the next set of cells.
Digits in this puzzle must be placed in the correct order (And this requires thinking ahead). Each digit you place must be a factor or multiple of the previously placed digit. E.g. since the first placed (given) digit is 4, the next placed digit must be selected from 1,2,4,8.
Digits may be placed in any order once ALL fog is revealed.
German Whispers: Adjacent digits along a green line have a difference of at least 5.
Killer: Digits do not repeat in cages, and sum to the small clue in the top left corner.
Tip: You may want to colour or mark the (currently) last placed digit, to help keep track.
Lösungscode: Row 8

This was amazing! It's my first time I've encountered the "fill digits in a specific order" rule and I had a blast solving it, and I solved it in around 50 minutes. My biggest time loss was keeping track which cells got revealed, at one point, I only spotted 4 out of the 5 revealed cells ^_^'

At one point during the puzzle I forgot to update my marker for the last placed digit.
Surprisingly the next set of digits still had a unique order even with a wrong starting digit. From the rules I would not have expected this to reveal fog, but somehow it did.
That meant that because of the incorrect order I started yet another set with an incorrect starting digit. And this set did not quite work.
Because the fog reveal had reaffirmed that the placed digits were correct it took me quite a while to figure out where this mistake was.

Really fun, and I for one found the rules clear and easy to follow! :)

The rules were hard to wrap my head around at first but this is an excellent new ruleset. I think it has a lot of potential. Looking forward to more.

AFTER I understood the rules, which took me a good ten minutes, it flowed wonderfully and it was a very enjoyable solve! Great original idea!

A beautiful use of fog to create mini puzzles along the way!

Lovely puzzle with avery interesting concept, it took a while to fully understand the rules but after that it flowed nicely. Quite the unique and creative idea, though probably harder than a 2* (3.5* for me). Thank you for setting, this one goes on my favourites!
