Theme: Logical

Author/Opus: This is the 6th puzzle from guest contributor Roger Barkan.

Rules: Combination of Star Battle and Cave. Place digits into two cells in every row, column, and region of the left grid (one cell in the example). Digits cannot touch, not even diagonally. The numbers in the upper-left of each region indicate the identity of the digit to be entered in that region. The digits must form a valid cave puzzle (which can be solved on the bottom grid).

The shaded cells in the bottom grid must be part of a pentomino in one of the two top grids; the unshaded cells cannot be part of a pentomino in either grid.

Answer String: Enter the length in cells of each of the shaded pentomino segments from left to right for the marked rows, starting with the two marked rows in the left grid and then with the two marked rows in the right grid. Separate each row’s entry from the next with a comma.
