Rules: Normal Sudoku rules apply. Put the digits 1 to 9 once each in each row, column and box.
Doublers: One cell in every row, column and box is a doubler. This cell counts as double its value for the following rules. Each of the digits 1 to 9 appears exactly once in a doubler cell.
Zipper Lines: Values an equal distance from the centre (marked by a circle) of a line sum to the value in the middle of that line. Different lines are different colours.
Fog of War: The grid is partially covered in fog. Placing correct digits will clear the fog from surrounding cells.

Nice ruleset and very good execution.

There's a step in the midsolve that is just delightful. The build up to that step is full of dramatic tension with lots of clever deductions, and afterwards the crescendo of digits fill the grid.
Truly satisfying setting!

For someone like myself, who isn't overly familiar with doublers (and finds them tricky), this was a fabulous puzzle to teach the concept and overall this was a very satisfying and enjoyable solve, where I learned some new things as I did it. Thank you!
