Sample:
Rules: Shade some empty cells black so that the grid is divided into white areas, each containing exactly one number and with the same area in cells as that number. Two white areas may only touch diagonally. All black cells must be connected with each other, but no 2×2 group of cells can be entirely shaded black.
Lösungscode: The length of the longest continuous black cell in each row starting from top to bottom.

I would love to try this with SudokuPad software, or Penpa. Colors are very useful, I can't solve it without.
