About:
This puzzle was created for Scojo's 2nd annual Secret Impostor event.
This was the real Andrewsarchus puzzle.
I successfully defended my identity against my imposter, Laake,
who set this charming puzzle: ┬─┬ノ( º _ ºノ)
which is a fitting sequel to my (╯°□°)╯︵ ┻━┻ puzzle.
Rules:
- Sudoku-ish rules apply:
- Digits may not repeat in a row, column, or 3x3 box in the main grid.
- Disjoint Groups:
- Digits occupying the same relative position within their 3x3 boxes in the main grid must be distinct.
- Doppelganger:
- Every row, column, and 3x3 box in the main grid must contain a 0, and must therefore omit one of the digits from 1-9.
- Each digit from 1-9 is missing from exactly one row, one column, and one box.
- For each 0, the digit missing in its row, column, and box must be three distinct digits.
- Three auxiliary grids are provided for recording the missing digits.
- The 9x1 strip below the main grid records the digit missing in the corresponding column of the main grid.
- The 1x9 strip to the right of the main grid records the digit missing from the corresponding row of the main grid.
- The 3x3 box in the lower right records the digit missing from the corresponding box of the main grid.
- 0-Coordinate Arrows:
- The digits on an arrow read from tail to tip are the row and column respectively of a distinct 0 in the grid.
- Circles:
- The digit in a circle counts the number of digits in the up to 8 surrounding cells which contain a digit from the set of digits missing from the circle's row, column, and box.
- All possible circles are given.
- Squares and Diamonds:
- Let R,C,V be the digits missing from the square's row, column, and box respectively.
- Then there is a diamond located in Row R, Column C, which contains the digit V.
- (Note the digit in the square is not relevant).
- All possible Squares and Diamonds have been given.

Certainly difficult, but it flowed really well once I asked the right questions. And of course I’m always partial to coordinate arrows. Thanks for the puzzle! :D

Doppelgangers are always fun, and this was excellent.
