Outside Nurikabe
This is the sibling to today’s Outside Nurikabe on the GMPuzzles blog. It’s harder, but shouldn’t be as bifurcation-heavy as the first one was.
Rules:
- Unlike in regular Nurikabe, the clue numbers have been placed outside the grid.
- A clue will appear in the first unshaded cell in its row/column, counting from the clue’s direction.
- Standard Nurikabe rules then apply:
- Shade some cells to form a continuous wall that contains no 2×2 squares of shaded cells.
- The clue numbers hint at connected groups of unshaded cells.
- Every group has exactly one clue, which tells the group’s size.
That was an awesome puzzle, thank you 🙂
Thanks! I think it’s my favourite of the ones I’ve made so far, too.
