I tackle LinkedIn Crossclimb #821 in three passes — middles first, ordering second, combo ends last. This 4-letter board runs HARD → … → WARE with combo clue "A compound word for the physical components of a computer.".
Middle phase: I work clues in board order — "Large group of animals like cows or sheep" → HERD; "In this location" → HERE; "Employ for a job" → HIRE; "Extremely serious, like some consequences" → DIRE; "Challenge someone to complete a task" → DARE.
Ordering phase: the valid middle chain is HERD → HERE → HIRE → DIRE → DARE. This permutation is the only valid one-letter chain for these answers.
I verify HARD to HERD — A→E at the second letter (HARD → HERD).
I verify HERD to HERE — D→E at the fourth letter (HERD → HERE).
I verify HERE to HIRE — E→I at the second letter (HERE → HIRE).
I verify HIRE to DIRE — H→D at the first letter (HIRE → DIRE).
I verify DIRE to DARE — I→A at the second letter (DIRE → DARE).
I verify DARE to WARE — D→W at the first letter (DARE → WARE).
Finished chain: HARD → HERD → HERE → HIRE → DIRE → DARE → WARE. Combo ends HARD + WARE clicked once ordering locked. Only one middle permutation forms a valid ladder from top to bottom — if ordering feels stuck, recheck a middle answer.
