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 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. All numbers in the puzzle are 1-9. A Fillomino Polyomino may not border a Suguru digit with the same value. An unshaded circled clue indicates the total number of unshaded cells seen in the four orthogonal directions, including the clue cell. A shaded circle clue indicates the size of the shaded region.
