- 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.
- ➍ All black cells must form an orthogonally contiguous area.
- ➎ The black cells must not cover an area of 2x2 cells or larger.
