RULES:
Cave: Shade some cells such that all orthogonally connected groups of shaded cells (the wall) touch the edge of the grid, and all unshaded cells (the cave) are orthogonally connected.
Suguru: Each orthogonally connected group of shaded (wall) cells contains the digits 1-N (where N is the size of the group). Suguru digits may not repeat in a row, column, or shaded group.
Fillomino: Divide unshaded cells (the cave) into polyominoes and fill each cell with a digit equal to the size of its polyomino. Polyominoes of the same size may not share an edge.
(Clarification: The use of the word “digit” in all contexts above indicates all numbers in the puzzle are 1-9)
Fillomino/Suguru Borders: A Fillomino Polyomino may not border a Suguru digit with the same value.
Circle Clues: An unshaded circled clue indicates the total number of unshaded cells seen in the four orthogonal directions, including the clue cell (shaded cells block vision). A shaded circle clue indicates the size of the shaded region.
Solution code: The shaded (wall) cells in Column 9 (3rd from last), then the unshaded (cave) cells in Row 2

Clarified rules to include that shaded cells indeed block vision of cave clues

Thanks for the puzzle, I enjoyed it. However, I struggled initially with the following rule: "An unshaded circled clue indicates the total number of unshaded cells seen in the four orthogonal directions, including the clue cell." It's unclear if shaded cells "block the view". I think it's a good idea to clarify that in the rules.

Question for clarity: A cave cell with a circle stops counting once it sees a wall, correct? Thanks.
- Yes, wall cells block vision of circled cave cells
