Negative Space [Meta-Renban Sudoku]
(Published on 12. April 2023, 10:41 by wisty)
This puzzle is dedicated to dumediat - thank you for being my most valuable tester, and setting puzzles that are fun and inspiring, and for being my friend! :)
Rules:
• Normal sudoku rules apply.
• Digits in circles must appear in at least one of the surrounding four cells.
• Marked diagonals must sum to the indicated totals.
• No line may form a set of four consecutive digits, however, all lines combine to form a Super Ultra Hyper Mega Meta Renban which can be divided evenly into sets of exactly four consecutive digits.
For clarity:
• Digits may repeat along marked diagonals.
• Line colors differentiate intersecting lines.
• In row 4, columns 3 and 7 are part of two different lines and thus counted twice.
• On individual lines, 1375, 4556, and 1239 are examples of valid fills. 2435 would not be allowed.
• An example of a valid complete set would be 45667789. An example of an invalid complete set would be 12345677.
• The "???" clue is purely there for symmetrical aesthetics and does not provide any information.
Solution code: column 1 followed by column 9

Wisty often makes puzzles that I feel like I might have made, but mine would have been far less subtle. This is one of those <3

bumped up the estimated difficulty due to the unusual break-in

You need one or better two good ideas for the break in.
