Fill in the grid so that every row, every column, and every 3x3 box contains the digits 1 through 8 and a chess bishop. All bishop defend at least one other.

Divide the grid into areas and write a number in every field. The numbers in the same area have to be the same and have to tell the number of fields in that area. Areas of same size my not touch horizontally or vertically, but diagonally. Given numbers may belong to the same area, and it's possible that there are areas, where no number is given, even with larger numbers as the once shown.

Example:

Puzzle:

Fill in the grid so that every row, every column, and every 3x3 box contains the digits 2 through 4. Each row, column, and 3x3 box contains two 2's, three 3's and four 4's.

Fill in the grid so that every row, every column, every 4 x 2 box and both main diagonals contain the digits 1 through 8. The sum of the digits within each sub-region is equal to the specified number. No digits can be repeated in any cage.
