The first clue, "The Sun", opens the board with intentional ambiguity. In Pinpoint, a single clue rarely proves the category — it is a starting hypothesis, not a verdict.
"Dominoes" narrows the field. A valid category must explain both "The Sun" and "Dominoes" with the same rule — not two separate stories.
By "Leopards", the category "Things that have spots" should start to feel inevitable. Three clues with one rule beats three clues with three excuses.
"Dalmations" adds another member of the same set. Each new row should strengthen "Things that have spots", not send you hunting for a new theme.
"Ladybirds / ladybugs (🐞)" is the stress test. If "Things that have spots" still fits naturally here, the puzzle is solved; if not, your category is too narrow or too broad.
Read together, "The Sun", "Dominoes", "Leopards", "Dalmations", and "Ladybirds / ladybugs (🐞)" converge on "Things that have spots". That convergence — one precise category, five varied clues — is the structure Pinpoint rewards.
