The Angel, Islington
Puzzle by Pallando and 'Fog of War' implementation by Chameleon.Standard sudoku rules apply.
Adjacent digits on golden clock lines differ by 2 or 7.
Equivalent distant digits on red anti-palindrome lines sum to 10.
Equivalent distant digits on violet weak palindrome lines match in Odd (13579) vs Even (2468) and in High (56789) vs Low (1234).
(Dots mark the mid-points of the palindrome lines.)
The grid is covered with fog. There is one initial 💡 light source that illuminates the darkness and clears the fog. Put correct digits into the cells to get more light (it's ok to put a digit into a cell that is covered by fog).
You have 5 lives to solve the puzzle. It takes 1 life to enter a wrong digit.
Note: no guessing is required to finish the puzzle. The extra lives are given only to allow room for possible typos.
To solve this puzzle, you must use (Sorry, due to the nature of the puzzle, no version printable on paper is possible.)Solution code: 18 digits, without spaces - row 9 from left to right, followed by column 9 from top to bottom.

Example of the weak palindrome rule, suggested by Dathan as being worth adding:
A "1" is low and odd, so it can match any digit that is also both low and odd: "1" or "3"
A "2" is low and even, so it can match any digit that is also both low and even: "2" or "4"
A "3" is low and odd, so it can match any digit that is also both low and odd: "1" or "3"
A "4" is low and even, so it can match any digit that is also both low and even: "2" or "4"
A "5" is high and odd, so it can match any digit that is also both high and odd: "5" or "7" or "9"
A "6" is high and even, so it can match any digit that is also both high and even: "6" or "8"
A "7" is high and odd, so it can match any digit that is also both high and odd: "5" or "7" or "9"
An "8" is high and even, so it can match any digit that is also both high and even: "6" or "8"
A "9" is high and odd, so it can match any digit that is also both high and odd: "5" or "7" or "9"

What a fun break-in and puzzle! The rules were a bit mind bending at the beginning but once I understood them the logic was very nice! Thank you

Very fun solve. I think slightly easier than 3 stars. After the break in it flows pretty smoothly

Clever break-in and smooth solve. Good choice of constraints for a "FOW" puzzle.

Changed "Der Engel" to "The Angel", in response to feedback about a translation error I introduced.

Der Name dieses Puzzles bezieht sich auf die Version ohne „Nebel des Krieges“, die „Mornington Crescent“ genannt wurde, nach einem Spiel, das auf BBC Radio 4 gespielt wurde und auf der Karte des Londoner U-Bahn-Systems basiert. Es bezieht sich auch auf das Buch „Neverwhere“ von Neil Gaiman und die Licht- und Dunkelheitsthemen, die es durchziehen.
The name of this puzzle is a reference to the non-'fog of war' version which was named "Mornington Crescent" after a game played on BBC Radio 4 based around the map of London's underground train system. It also refers to the book "Neverwhere" by Neil Gaiman and the light and darkness themes running through it.
