LinkedIn Crossclimb #850 is a 4-letter Crossclimb ladder from JACK to POTS. Phase one is crossword solving: 5 middle clues yield BACK, BACH, BATH, PATH, PATS. Phase two is ordering; phase three unlocks the combo ends tied by "A compound word for what is paid out by slot machines (also known as fruit machines or poker machines).".
Middle phase answers: "Returned from a trip abroad" = BACK; "Johann Sebastian ___ (German composer)" = BACH; "Alternative to a shower" = BATH; "Route from one place to another" = PATH; "Gently touches, as a pet dog" = PATS.
Ordering phase: the valid middle chain is BACK → BACH → BATH → PATH → PATS. This permutation is the only valid one-letter chain for these answers.
Link JACK → BACK: J→B at the first letter (JACK → BACK) (combo-adjacent).
Link BACK → BACH: K→H at the fourth letter (BACK → BACH).
Link BACH → BATH: C→T at the third letter (BACH → BATH).
Link BATH → PATH: B→P at the first letter (BATH → PATH).
Link PATH → PATS: H→S at the fourth letter (PATH → PATS).
Link PATS → POTS: A→O at the second letter (PATS → POTS) (combo-adjacent).
Complete ladder: JACK → BACK → BACH → BATH → PATH → PATS → POTS. The combo clue "A compound word for what is paid out by slot machines (also known as fruit machines or poker machines)." describes both end words together — "JACK" and "POTS" 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.
