This puzzle took some time to create, but finally I was able to find a combination of row/column indexers and Renban lines which works really well. Have fun solving it, and I appreciate your ratings and comments.

Rules:

• Normal sudoku rules apply.
• Digits on a purple Renban line must be a set of consecutive, non-repeating digits (in any order).
• Shaded cells are simultaneously column and row indexers, i.e. digit X in a shaded cell in row R, column C indicates that digit C appears in column X in row R, and digit R appears in row X in column C (see example below).
• Digits connected by an X must sum to 10. Not all Xs are given.

Example:

In the following example, the 2 in r4c5 forces a 4 into row 2 and a 5 into column 2. Similarly, the 8 in r6c4 forces a 6 into row 8 and a 4 into column 8.
