Da Copycat Present

(Published on 9. May 2026, 01:40 by ChinStrap)

Rules

  1. Copycat Cells: Place 9 Copycat Cells into the grid so that there is exactly one Copycat Cell in each row, column, and 3x3 box. Each Copycat Cell must contain a different digit. The value of a Copycat Cell is the digit in the cell rotationally opposite itself in the grid, using a 180° rotation about the center of the grid. For example, if r2c3 is a Copycat Cell containing the digit 5, and r8c7 contains the digit 9, the value of r2c3 is the digit in r8c7, which is 9.
  2. Double Arrows: Values on lines sum to the sum of the values of the attached circles on either side of the line.
  3. X-Sums: Clues outside the grid indicate the sum of the first X values from the direction of the clue, where X is the first value in that direction.

Notes

Definitely one of the most approachable copycat puzzles out there, which is something the variant desperately needs more of. I also know from experience that writing words in the grid with lines is very hard to do if you still want control over a good solve path, but you managed it! Thanks!
