Rules

• Normal sudoku rules apply. Fill the grid such that the digits 1-9 appear once in every row, column, and 3×3 box.
• Negator Cells: In each row, column, and box there is one Negator cell to be found. Each Negator cell contains a different digit. The value of a Negator cell is the negative of its digit, e.g. an 8 in a Negator cell has a value of -8.
• Killer Cages: Values in cages cannot repeat, and sum to the magnitude shown in the top left corner.
• German Whispers: Adjacent cells on a green striped line must differ in value by at least 5.
• Region Sum Lines: Box borders split blue lines into sections. All of the sections on a line must have the same sum value.
• Kropki dots: In cells connected by a white dot, values must be consecutive. In cells connected by a black dot, one value must be exactly double the other. Not all dots are given.
