4 Choose 2

Rules:

Normal sudoku rules apply. Digits separated by an X sum to 10. Grey lines must each follow exactly two of the following four rules:

-German Whisper: adjacent digits on the line must have a difference of at least 5.

-Ten Line: the line consists of one or more contiguous groups of cells, each of which sums to 10. These groups of cells cannot overlap.

-Palindrome: the sequence of digits along the line reads the same in either direction.

-Region sum: the sum of the digits along the line must be the same within each 3x3 box the line passes through.

Every grey line must follow a different pairing of two rules e.g: if one line is a Palindrome and a German Whisper, another line cannot be both a Palindrome and a German Whisper.

CTC

Solution code: Row 7 followed by row 9.

Very nice! The more challenging part for me was the sudoku at the end and not figuring out and using the lines oops
