# Solution to Nik-holey

### by Ricky Liu

Each puzzle has had a number removed from its center square. There is a unique number that can be placed in that square such that the puzzle then has a unique solution. (There are other clues for that square that yield solutions, but those solutions will not be unique given the clue.)

**Nurikabe**

**Slitherlink**

**Hitori**

**Heyawake**

**Fillomino**

**Hashiwokakero**

In order, the removed clues are 6, 1, 3, 1, 4, and 5. Converting into letters gives the answer, FACADE.
