PUZZLE
RULES
Sudoku: Normal Sudoku rules apply; place the digits 1-9 once in every row, column, and 3x3 box.
Copycat Cells: There exist 9 Copycat Cells in the grid such that there is exactly one Copycat Cell in each row, column, and 3x3 box. Digits of Copycat Cells do not repeat. The value of a Copycat Cell is the digit in the cell rotationally opposite itself in the grid (180° rotation about the center of the grid). For example, if r4c3 is a Copycat Cell containing the digit 8, and r6c7 contains the digit 5, the value of r4c3 is the digit in r6c7, which is 5. It is up to the solver to determine the position of each Copycat Cell.
Arrows: Digits along an arrow sum to the digit in the circle.
Killer Cages: Digits in a cage do not repeat, and must sum to the value indicated in the upper leftmost corner.
