Rules: Variation of Nurikabe. Shade some empty cells black so that the grid is divided into white areas, each containing at most one number. A white area with a number must have the same area in cells as that number. White areas may only touch diagonally. All shaded cells must be connected with each other, but no 2×2 group of cells can be entirely shaded. Also, all shaded cells must be divisible into snakes with the heads and tails given in the grid. Snakes cannot cross each other.

Author/Opus: This is the 79th puzzle from our contributing puzzlemaster Prasanna Seshadri.

Rules: Find a path from one dot to the other by moving horizontally or vertically between adjacent squares. The path cannot touch itself, even diagonally. All highlighted regions must be visited by the path, and may be re-entered. If two or more highlighted regions have the same shape and orientation, then how the path passes through those shapes must be identical. Or see here.

Answer String: Enter the length in cells of the horizontal path segments from left to right in the marked rows, starting at the top. If the path only has vertical segments in the marked row, enter 0. Separate each row’s entry with a comma.
