Difficulty:The Break-In should be the only thing that is harder than 1 star, but should not be very hard.

Story: As Trekkies might realize from my nickname I am a Deep Space Nine Fan. My favourite episodes are the ones playing in the mirror universe. So why not do a Sudoku with this theme? Trekkies will already know: The mirror universe and our universe are similar but not the same. This is represented by slightly different rules in both in this sudoku. As I also wanted to do something pandemic themed, why not combine them?

Rules:

• Normal Sudokurules: Digits can not repeat within rows, columns and boxes.
• Two Universes:The green diagonal is the border between the normal universe and the mirror universe. Which is which has to be determined by the solver.
• Mirror universe:Digits mirrored at the green line have a sum of 10. (Example: a 2 in R2C2 forces 8 in R8C8, a 3 in R1C6 forces a 7 in R4C9).
  • Infected cells:Cells with a value of 4, 5 or 6 are infected. They and their mirror don't have to sum to 10 (but they can).
• Kropkidots:Not all Kropkidots are given
  Standard white dots:Cells connected by a white dot have to be consecutive in both universes. Nonstandard black dots:
  • Normal universe: Normal rules. Two cells connected by a black dot have a ratio of 1:2.
  • Mirror universe: Two cells connected by a black dot have a ratio of 1:3.
• Sudoku Universe Police (SUP): The SUP started to islate infected cells.
  • Normal universe: In the normal universe all coming togethers (two or more horizontal or vertical connected) of infected cells are encaged. This means in the normal universe in cages you only have 4s, 5s or 6s.
  • Mirror universe: In the mirror universe the SUP is acting overcarefully and also encages noninfected cells. Coming togethers that sum to 9, 10 or 11 are encaged. They can also include other digits than 4, 5 or 6. In the mirror universe not all cages are given.
