• Fill in the empty squares with numbers, so that the grid gets divided into blocks (squares one next to the other horizontally or vertically) formed by the same number of squares as the number written in each square.
For example a block of 2 will have 2 squares with the number 2 written in them, a block of 3 will have 3 squares with the number 3 written in them, and so on.
• A block of a certain amount can’t be adjacent to another one of the same amount horizontally or vertically, but diagonally this is possible.
• You may mark the different blocks with your pencil.
• All the squares belong to a block.
• It is possible that no clue is given for a block or that more than one clue is given for the same block.
