Najpierw mechanizm
We start with the relationship between the facts and one possible solution. The plot is supposed to reinforce them, not mask the lack of logic.
How a good puzzle is made
Climate is important, but it cannot replace honest construction. A good case is satisfying because the answer can be derived from the facts - not because the author withheld key information.
Wszystko jest w sprawie
No knowledge outside the material should be needed to make a correct conclusion. What matters is careful reading, comparing accounts and the sequence of events.
Editorial before publication
We remove repetitions, random clues and sentences that reveal the solution. Each tip is intended to have a specific function.
Test without knowing the answer
The puzzle must be solved by a person who does not know its structure. If he has to guess or sees two equally good answers, it comes back to improvement.
