LinkedIn Crossclimb #860 is a 4-letter Crossclimb ladder from HIDE to SEEK. Phase one is crossword solving: 5 middle clues yield SIDE, SITE, SITS, SETS, SEES. Phase two is ordering; phase three unlocks the combo ends tied by "Two antonyms that form the name of the children’s game “___-and-___” where one person is “it” and looks for the other players.".
Middle phase answers: "One of eight in an octagon" = SIDE; "Page to visit on the internet" = SITE; "Uses a chair" = SITS; "Drops below the horizon, like the sun at the end of the day" = SETS; "Lays eyes upon" = SEES.
Ordering phase: the valid middle chain is SIDE → SITE → SITS → SETS → SEES. This permutation is the only valid one-letter chain for these answers.
Link HIDE → SIDE: H→S at the first letter (HIDE → SIDE) (combo-adjacent).
Link SIDE → SITE: D→T at the third letter (SIDE → SITE).
Link SITE → SITS: E→S at the fourth letter (SITE → SITS).
Link SITS → SETS: I→E at the second letter (SITS → SETS).
Link SETS → SEES: T→E at the third letter (SETS → SEES).
Link SEES → SEEK: S→K at the fourth letter (SEES → SEEK) (combo-adjacent).
Complete ladder: HIDE → SIDE → SITE → SITS → SETS → SEES → SEEK. The combo clue "Two antonyms that form the name of the children’s game “___-and-___” where one person is “it” and looks for the other players." describes both end words together — "HIDE" and "SEEK" 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.
