This is my take on a Scojo prompt, in call to arms for more approachable Doppelgänger puzzles in the world.

If you have any questions feel free to DM me on Discord.

Happy solving!

Rules:

• Doppelgänger Sudoku:

  • Fill each cell of the main grid such that every row, column and box contains a 0 and five different digits from 1-6.

  • No two rows, no two columns and no two boxes may be missing the same digit.
  • For each 0 in the grid, the digits missing in its row, column and region must be three different digits.
  • Fill each outer cell with the digit missing from the corresponding row, column, or box.

• Fivetropy Lines: Every set of 3 adjacent digits on a peach line must contain a digit from each of the V-pair (five-pair) subsets of 05/14/23. Digits on a line may repeat if allowed by other rules.

• Kropki Dots: Digits separated by a white dot are consecutive. Digits separated by a black dot have a 1:2 ratio. Not all dots are necessarily given.
