Rules
Standard Sudoku: Place a digit from 1 to 9 in each cell so that each row, column, and outlined box contains exactly one of each digit.
159 Column Indexing: If digit X appears in row N of column 1, then 1 appears in row N, column X. Similarly for columns 5 and 9.
Index Lines: On a blue index line, if digit X appears in the Nth cell counting from the diamond, then digit N appears in the Xth cell from the diamond.
Lösungscode: Digits of column 7, top to bottom.

Lovely and actually quite approachable if you know the secrets of index lines and 159s

My first time solving this variant (not sure if it is unique). Greatly enjoyed unwrapping it. Thanks!
