This is my favorite puzzle so far. Please enjoy.Rules
Normal Sudoku rules apply. Place the digits 1–9 exactly once in every row, column, and 3×3 box.COPY CATS: Find nine Copy Cat cells in the grid, one in each row, column, and 3×3 box, each containing a different digit. The value of a Copy Cat equals the digit in the cell that is 180° rotationally opposite it in the grid.
Example: If r8c6 contains the digit 5 and r2c4 is a Copy Cat cell, then r2c4 has the value 5, regardless of the digit it contains.
DOG BONES: There are two dog bones in the grid. These cells are not copy cat cells and they both contain the same digit.
PALINDROME: Values along the gray line read the same forwards and backwards.
V CLUES: Cells joined by a V have values that sum to 5.
GERMAN WHISPERS: If two cells are joined by a green line, the values must differ by at least 5.
KILLER CAGES: Values in a cage sum to the total given in its top-left cell.
Solution code: Center (5th) column read top to bottom.

Could you clarify, can the same *value* appear twice in a cage?
