This is my submission to Scojos secret imposter prompt. I tried to make it as gdc as possible, but ViKingPrime out-gdcd me with S-Duality. Thanks to all the testers. Hope you enjoy!

• Sudoku: Normal Sudoku rules apply.
• Fog Of War: The grid is covered in fog. Placing correct digits reveals clues in the surrounding 3x3 area.
• Spiral Galaxies: Divide the grid into galaxies: orthogonally connected groups of cells that have 180 degree rotational symmetry about their centers (marked with a large circle). All cells must be part of a galaxy; no galaxies overlap.
• No Repeats: Digits may not repeat in a galaxy.
• Zipper Galaxies: A "Z" orbiting a galaxy center marks a zipper galaxy where each digit and the cell rotationally opposite to it sum to the circled digit.
• Galaxy Totals: If given, a digit orbiting a galaxy center shows the sum of all digits in that galaxy.
