Loopy: Unique/Non-unique Solutions in How to Play #561

Open nathanb01 opened 1 year ago

Could you include a statement in Loopy's How to Play section about whether solutions are always unique or not? This would help make decisions in some cases.

Example setup: 20220816_002241

Possible outcomes: 1 (Below): 20220816_002452 2 (Below): 20220816_002611 3 (Below): 20220816_002751

If solutions are unique, I can rule out outcomes 1 and 2 because they can be interchanged without affecting the rest of the puzzle. This would leave me with one possible outcome and I can use this outcome continue solving the rest of the puzzle.

^+1 This is especially tough when expecting unique solution per all other versions I have seen
