We've seen in the past that answer keys have not been consistent across puzzles tests, and sometimes across puzzles in the same test.
Also, some of the answer keys have been error-prone to find / type, while in some cases answer keys have been little guessable.

I'm starting this thread so that we can discuss puzzle types and what the answer key should be.
This thread should work as a reference point for future authors. Or eventually, we can just make a document out of this thread and share with future authors.

With so many puzzles, I was not sure how to list the types.
We can probably start test wise, i.e. starting from Evergreens so we will cover all types that has appeared at LMI earlier.

If someone has other ideas, please share.

Also, we'll not discuss any type for which answer keys are always fixed (e.g. Sudoku like puzzles)

It is difficult to list all puzzle types in single thread. So better to put them in a separate sub forum.
