LinkedIn Crossclimb #910 is a 4-letter Crossclimb ladder from HAIR to BALD. Phase one is crossword solving: 5 middle clues yield HAIL, SAIL, SAID, SAND, BAND. Phase two is ordering; phase three unlocks the combo ends tied by "Something often found on top of the head, and a word for someone who lacks it.".
Middle phase answers: "Solid precipitation" = HAIL; "Travel using wind power" = SAIL; "Spoke aloud" = SAID; "Beach surface" = SAND; "Word that can follow "rubber" or "marching"" = BAND.
Ordering phase: the valid middle chain is HAIL → SAIL → SAID → SAND → BAND. This permutation is the only valid one-letter chain for these answers.
Link HAIR → HAIL: R→L at the fourth letter (HAIR → HAIL) (combo-adjacent).
Link HAIL → SAIL: H→S at the first letter (HAIL → SAIL).
Link SAIL → SAID: L→D at the fourth letter (SAIL → SAID).
Link SAID → SAND: I→N at the third letter (SAID → SAND).
Link SAND → BAND: S→B at the first letter (SAND → BAND).
Link BAND → BALD: N→L at the third letter (BAND → BALD) (combo-adjacent).
Complete ladder: HAIR → HAIL → SAIL → SAID → SAND → BAND → BALD. The combo clue "Something often found on top of the head, and a word for someone who lacks it." describes both end words together — "HAIR" and "BALD" each differ by one letter from their adjacent middle rungs and satisfy the shared top+bottom prompt. Pattern: unique middle order — Only one middle permutation forms a valid ladder from top to bottom — if ordering feels stuck, recheck a middle answer.
