The brief
Normal sudoku rules apply.
Along thermometers, digits must increase from the bulb end. Digits in cages must sum to the small clue in the top left corner. Adjacent digits along an orange line must differ by at least 4. Digits in a quadruple clue must appear at least once in the four surrounding cells.
The following lines all go straight where they cross.
Digits along a blue line sum to the same value in each 3x3 box the line passes through. Adjacent digits along a green line must differ by at least 5. Digits along a purple line are a set of consecutive, non-repeating digits in any order. No two digits on a golden line can be consecutive, regardless of their order along the line.
