Unsealed, by James Sinclair
Normal sudoku rules apply.
Zipper lines: along lavender lines, each pair of digits that are the same distance from the center of the line have a sum equal to the digit in the center cell.
Digits in cells separated by a black dot have a 1:2 ratio.

It took me forever to ask the right question to unlock the puzzle, and yet that question now seems obvious. That's because it's a brilliant puzzle!

Loved this puzzle, not terrible hard to get started and it makes you think you're smart enough to solve the puzzle.
A bit later (after that feeling has faded) the puzzle suddenly solves itself. Thank you for sharing!

I got off to such a great start and then stared for an hour. Almost tempted to solve it again without all the head scratching! Thanks James :)

Amazing! After the somewhat easy break-in I stared at the grid for an hour or so, almost gave up, but then… in the end I was really satisfied. Thank you very much for creating and sharing this wonderful puzzle.
