➊ Blacken some cells of the diagram [paper] resp. color the
gray cells of the diagram black or white [interactively].
➋ Cells with numbers are always white. The numbers indicate
how many of the
orthogonally and diagonally adjacent cells are black: Each number
indicates a group of orthogonally adjacent black cells; different groups are
separated by at least one white cell. Position and sequence of the clue
numbers is irrelevant.
➌ A question mark indicates "any number" greater than zero.
➎ The black cells must not cover an area of 2x2 cells or
larger.
