From Wikipedia, the free encyclopedia

An eight-by-eight Shakashaka puzzle grid. Some of the spaces are pre-filled with black squares (some of which contain numbers); others are blank spaces to be filled with triangles.

Shakashaka (シャカシャカ) is a logic puzzle developed by publisher Nikoli.[1]

Rules

Shakashaka is played on a rectangular grid of white and black squares. Some black cells may contain a number.

The objective of the puzzle is to place triangles in some of the white cells. There are four kinds of triangles which can be put in squares:

In the resulting grid,

  • The white parts of the grid (uncovered by black triangles) must form a rectangle or a square.
  • Black cells with a number must be orthogonally adjacent to the specified number of black triangles.[2]

Computational complexity

It is NP-complete to decide whether a given Shakashaka puzzle has a solution.[3] Furthermore, counting the number of solutions to a given Shakashaka puzzle is #P-complete.[3]
