Rules: Normal sudoku rules apply. In each row, a digit N points to column N. Following these pointers decomposes the row into cycles. If a cell contains a horizontal mark, it belongs to a cycle whose length is equal to its digit. Analogously, in each column, a digit N points to row N, decomposing the column into cycles. If a cell contains a vertical mark, it belongs to a cycle whose length is equal to its digit. Not all possible marks are necessarily given.
Example: The row 645213798 consists of four cycles: 6->3->5->1->6, 4->2->4, 7->7, and 9->8->9. The digit 2 could therefore have a horizontal mark, since it belongs to a cycle of length 2 (but it need not have one).
Note: Rows are numbered from top to bottom, and columns from left to right.
Lösungscode: Row 9

Excellent puzzle. It brought back memories of this one by feadoor https://logic-masters.de/Raetselportal/Raetsel/zeigen.php?id=000OJ2 which uses cycle sums rather than cycle counts.
I was surprised at how naturally this solved - it looked as though it might take more work.

Many greetings to SirSchmoopy. He created several 'cycle' sudokus.

Neat solve path, one to try again after brain finally becomes attuned to the logic!

Outstanding puzzle. The ideas here are quite fresh, and the logic is very nice.
