Complete instructions

You start with a rectangular board with some numbers in their boxes. One has to get the number of contiguous free boxes horizontal and vertical of each number (including its own box) is equal to the number of the number. To do this, we can paint black boxes to delimit the boxes accessible from each number. The adjacent boxes are counted until we find a covered box or until we reach the end of the board. The numbered boxes are also counted as free. There are these limitations when solving the game:
  • It is not possible to paint the numbered boxes in black.
  • There cannot be two black boxes horizontally or vertically.
  • All unpainted boxes are linked in a single region, this means that there cannot be a group of black boxes that divide the board into two or more parts. That is, from any unpainted box, we can move horizontally or vertically and we can reach any other unpainted box
  • For any numbered box, the value indicates the number of unpainted boxes that we can reach horizontally or vertical until reaching a black painted box at the end of the board. The numbered box is included in the account (only once)
