How to Play
Goal: Paint cells black or leave them white to match all row and column clues.
- Numbers outside the grid show how many cells should be black in that row/column.
- Click or tap a cell to toggle it between white and black.
- Use deduction: if a row clue is 0, leave it all white.
- Cross-reference rows and columns to solve each puzzle.
- Each puzzle has exactly one unique solution!
Tips: Start with rows/columns that have 0 or maximum clues. Use hints if stuck.
