This puzzle was produced for one of Scojo's Setting Saturday weekly puzzle prompts. The randomly selected constraints required were palindromes, german whispers and deconstruction.

Deconstruction sudoku: Place 9 non-overlapping 3x3 regions in the grid. Each containing the digits 1-9. Digits may not repeat in any row or column.

German Whispers: The value of adjacent cells along a green line must differ by 5 or more.

Palindromes: The sequence of values of cells along a grey line must be the same when read from either end.

Yellow lines are either German Whisper Lines or Palindromes, to be determined.

For the purposes of whispers and palindromes, if a line passes through a cell not in a region, the value of that cell is considered to be zero. (zeroes/empty cells may repeat in rows and columns).
