Despite being the second puzzle I’ve posted, this is the first 9x9 puzzle I’ve ever set and I’m pretty proud of it. Made for my girlfriend’s birthday this weekend.
Rules:
Normal Sudoku Rules Apply: Place the digits 1-9 in every row, column and box once each.
Echo Line: The blue line is filled with a repeating sequence of one or more different digits. The full sequence must appear at least twice along the line and must always repeat in its entirety.
Renban Lines: Digits along a pink line form a non-repeating consecutive sequence, arranged in some order.
Killer Cages: Digits in cages must sum to the given total. Digits may not repeat within a cage.
For our colorblind friends: The echo line starts in r1c1 and ends in r8c8. Any bits that seem to branch off of this line are renbans.
Lösungscode: All the digits along the echo line starting from r1c1 (12 digits)

I suggest you clarify the rules a bit, for our color blind friends, it might be difficult to understand if the line stops at r8c8 or continues till r7c6 (it might look like the pink and blue lines are just one single line for them). Although you mentioned "12 digits", it's better to clarify the rule I suppose
