This puzzle is my take on the cover of Dark Side of the Moon by Pink Floyd. The puzzle can be viewed with Sudokupad's dark mode enabled for the full effect, but that is not required for the solve.

Normal sudoku rules apply. Place the digits 1-9 once each in every row, column and 3x3 box.

• Digits along a thick grey line must be strictly between the values in the circles at either end.
• Digits along a thin grey arrow must sum to the number in the attached circle.
• Digits separated by a X must sum to 10, while digits separated by a V must sum to 5. Not all Xs or Vs are given.
• Adjacent digits along a red line must alternate in parity (odd/even).
• Adjacent digits along an orange line must have a difference of at least 4.
• Adjacent digits along a green line must have a difference of at least 5.
• Digits on a blue line must have the same total for each region the line enters. Different lines may have different totals.
• Digits along a purple line can be arranged into a consecutive sequence of non-repeating digits, but may appear in any order.

The puzzle is available online via Sudokupad
