As said before, the following puzzle is the second part of a two-part entry of my new mini-series with pencil puzzle hybrids. For the first part with specific examples, check out this link.

This second part is a lot more consistent in terms of difficulty but should also offer a lot more fascinating stuff overall. I hope you enjoy this main serve!



Rules:

1) ABC-Box rules apply:
In the 12x12 grid, fill each cell with one letter from A, B or C. For some particular row/column, a series of clues is provided for them respectively and the series implies a few things below:

- The number of clues corresponds to how many blocks of the same letter are within that row/column. No two orthogonally adjacent such blocks will contain the same letter to each other.
- The order of the clues is from left to right for rows and from top to bottom for columns.
- A letter clue indicates the letter to be filled in its respective block, and the length of that block is non-zero but actual value is unknown.
- A number clue indicates the length of its respective block that contains the same letter, but that letter is unknown (>X means that the length is greater than X).
- A question mark (?) implies that its respective block contains an unknown single letter and the length of that block is non-zero but actual value is also unknown as well.

2) In addition, the puzzle also functions as a cave puzzle for the letter C: All cells containing letter C will form a single orthogonally connected area, and each orthogonally connected area of the cells not containing letter C will connect to the 12x12 grid border.
