The structural clue

How the ladder gives itself away

FOSTER → POSTER starts the chain with a change in position 1. From there, the changed positions run 1, 2, 1, 2, 3, 4, which is a quick way to verify the order without relying on meaning alone.

  1. StepSolve the middle clues, then anchor POSTER beside FOSTER because they differ at exactly one position.
  2. StepContinue through POSTER → PESTER → FESTER → FASTER → FATTER, checking spelling position by position rather than grouping words by topic.
  3. StepPlace FATHER at the other endpoint and use the shared endpoint clue to connect FOSTER with FATHER.

AI-assisted guide · How it is produced

Welcome to our strategy guide for LinkedIn’s Pinpoint. This daily puzzle gives you five clues and challenges you to find the single category that unites them all. Unlike grouping games, your goal is not to divide a board into several sets. The entire puzzle is five clues, one hidden connection. Success requires logic, lateral thinking, and a willingness to reconsider an early idea. The clue board on our homepage shows all five clues at once, allowing you to see the full picture as you apply these techniques.

The complete guide includes worked examples, alternative meanings, and checks for connections that do not fit all five clues.
