Translate the puzzle into facts
Separate what is given from what you assume. Words such as all, some, only, before and exactly change the rule and should be treated precisely.
For visual logic, describe the relationship in plain language. A short sentence such as “the filled shape moves one place clockwise” is easier to test than a vague impression.
Test constraints one at a time
Start with the strongest constraint: a fixed position, an impossible pair or an exact count. It usually removes the most options with the least work.
Keep temporary possibilities separate from proven facts. A choice that works with one clue can still fail another, so do not promote it to an answer too early.
Finish with a contradiction check
Before confirming, apply every clue to the remaining answer. One contradiction is enough to reject it, even if the rest looks plausible.
When time is limited, elimination is often efficient: prove why three options cannot work rather than building a complete proof for all four.
