This puzzle is part of the Monthly Topic Challenge #13: Variety Slitherlinks.
This is a Slitherlink-Yajilin hybrid. Shade some cells in the grid and draw one non-crossing, non-branching line connecting centres of cells horizontally and vertically, so that the final configuration satisfies the rules of both puzzle types.
Rules of Slitherlink:
- Blue numbers are Slitherlink clues. Each clue indicates how many of the four possible line segments surrounding the number are used for the loop.
Rules of Yajilin:
- Black numbers with grey background are Yajilin clues. The clue indicates how many shaded cells are in the direction of the arrow.
- Two shaded cells cannot share an edge, but they can touch at a corner. Shaded cells can touch clue cells.
- The loop must visit every empty cell in the grid (i.e. every cell that's not shaded and not a clue).
