Tapa Islands Hard

Tapa Islands Rules:

• Islands and Cells:

  • White cells form separate enclosed areas ("islands") surrounded by black cells.

  • Each island can contain at most one clue cell.

• Clue Cells:

  • If a clue cell is present within an island, at least one of its digits should represent the size (in unit squares) of that island.

  • Clue cells may contain multiple digits separated by commas. Each digit represents the size of a distinct connected area of black cells within the island.

  • The black cell areas corresponding to different digits within a clue cell must be separated by at least one white cell.
