Sudoku: Fill every row, column and 3x3 box with the digits 1-9.
Killer: In cages marked with a dashed line digits must not repeat. The cell values (see modifier rule) must add up to the total given in the top left corner of a cage.
Modifier Entropy: Each cell in the grid belongs to one of the following three groups:
1. Normals: The cell value equals the digit in the cell.
2. Doublers: The cell value is twice the digit in the cell.
3. Negators: The cell value is the negative of the digit in the cell.
The grid must fulfill the following properties:
1. Each row, column and marked 3x3 box contains 3 cells of each group.
2. Each 2x2 area in the grid contains at least one cell of each group.
Attention!: In this entropy variant there is no grouping according to digits. All 9 digits can appear in all three groups.
Have fun solving!
Solution code: Row 9 followed by column 9 (18 digits)
