Nurisho

      Nurisho is a variant of nurikabe that uses center symmetry to define regions. IT IS NOT NURI-UZU. Here are the rules :

    Shade some cells on the board to create unshaded regions.

- No 2x2 square can be entirely shaded.

- All shaded cells form an orthogonally contiguous area.

- A region is defined by its center of symmetry, located at a white dot. All white dots are given and all reginos must contain a dot.
