This puzzle is part of the Monthly Topic Challenge #13: Variety Slitherlinks.
Below is a grid containing multiple small slitherlinks. These can be independently solved to form clues for the large metaslitherlink.
The following standard rules apply to all slitherlinks:
- Connect adjacent dots with vertical or horizontal lines to make a single loop.
- The numbers indicate how many lines surround it, while empty cells may be surrounded by any number of lines.
- The loop never crosses itself and never branches off.
The solved metaslitherlink should reveal a number, which is the final answer to this puzzle.
