Standard sudoku rules apply: each row, column, and 3x3 box must contain all the digits from 1 to 9.
Cages: digits in a cage must not repeat, and sum to the total in the upper left corner of the cage, if given. Together, the cages without totals sum to 157.
Renban: a magenta line denotes a non-repeating set of consecutive digits, in any order.
Whisper-5: adjacent digits along a green line must have a difference of at least 5.
Solution code: Enter, in ascending order without spaces, the digits which appear in all four cages without totals. E.g. 12478

@Snookerfan My estimate for the difficulty was 4. A tester thought it was 2. So I called it 3. I am very interested to see how it gets rated here.

I feel pride plus for solving this very hard puzzle, including the solution code. Apparantly this is a 3 star puzzle, so I solved it without noticing some obvious things. Thanks!
