Perplexible

This is already the fourth one of these I’ve made, which I consider a feat given how many of my puzzles tend to be one-shot variations.

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.

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.

This one took a bit of wrangling to make it work, because I insisted on having the diagonal read 1-2-3-4-5 whle keeping it litsable. Anyways,  I like how it turned out.

Rules: It’s a Nurikabe. It’s also a borderless LITS; or equivalently, the filled area must be tileable with tetrominoes such that no two of the same shape share an edge. Lastly, the numbers outside the grid tell how many tetrominoes are in that row/column.
