Identische Hinweise - Höhle und Inseln
(Published on 23. February 2018, 18:00 by pirx)
The puzzle grids contain the same clues for two different puzzle types. Some clues have been replaced by question marks; a pair of question marks represents the same clue number in both puzzles.
Cave
A cave system must be found in the grid, that is, some cells must be shaded black such that the following conditions are satisfied.
A cave system must be found in the grid, that is, some cells must be shaded black such that the following conditions are satisfied.
- The interior of the cave (the white cells) is horizontally and vertically connected,
- The walls (all the shaded cells) are connected with the boundary of the grid,
- All cells containing a number are inside the cave; the number indicates how many cave cells can be seen horizontally and vertically from that position, including the cell with the number itself,
- No 2x2-area is completely inside the cave.
Nurikabe
Shade some empty cells black so that the grid is divided into white areas, each containing exactly one number and with the same area in cells as that number. All black cells must be connected with each other, but no 2x2 group of cells can be entirely shaded black.
Shade some empty cells black so that the grid is divided into white areas, each containing exactly one number and with the same area in cells as that number. All black cells must be connected with each other, but no 2x2 group of cells can be entirely shaded black.
One shaded cell is already given.
Solution code: The main diagonals from top left to bottom right: at first the cave, then the Nurikabe ("W" for cave and island, respectively, "S" for black cell).
