A birthday present for Scojo, one of the best guys in the community. Had to use his modifier invention of course.

Rules:

• Normal 6x6 sudoku rules apply.
• Copycat Cells: Place 6 copycat cells into the grid so that there is exactly one in each row, column, and 2x3 box, and each contains a different digit. A copycat cell has the value of the digit in the cell rotationally opposite itself in the grid (180° rotation about the center of the grid). For example, if r2c3 is a Copycat Cell containing the digit 5, and r5c4 contains the digit 3, the value of r2c3 is the digit in r5c4, which is 3.
• Index Lines: The value in the Nth cell along a thicker cyan line (starting from the diamond) indicates the position along the line where the value N appears. For example, if a diamond cell has a value 3, the third cell along that line must have a value 1.
• Renban Lines: Values on the thinner pink lines must form a consecutive sequence when sorted.
• X-Sums: Digits outside the grid indicate the sum of the first N values, where N is the value in the closest cell to the clue.
