Logic Masters Deutschland e.V.

There was a Setting Saturday prompt to do a remix of our first puzzle, and doing something like that for "Slapdash" had been on my mind for a while anyway, so I took the opportunity.

There may seem to be some extra clues here, but you know me, I like my symmetry! Besides which, the diagonals, Kropkis and thermos are the same configuration as the original, just without the given digits.

Rules:

- Normal Sudoku rules apply, and each full diagonal also contains the digits 1 to 9.

- Thermometers - digits along a gray thermometer must increase in value from the bulb to the tip.

- Palindromes - the string of digits along a thin gray palindrome must read the same backwards and forwards.

- Kropki dots - digits separated by a white Kropki dot are consecutive; digits separated by a black Kropki dot have a 2:1 value ratio. No negative constraint.

- Dutch Whispers - neighboring digits on an orange Dutch Whisper line must differ in value by at least 4.

- Modular lines - any set of three adjacent digits on a teal modular line must come from each of the three following sets: [1,4,7], [2,5,8], and [3,6,9].
