I tackle LinkedIn Crossclimb #781 in three passes — middles first, ordering second, combo ends last. This 4-letter board runs MASK → … → PUCK with combo clue "Something an ice hockey goalie wears, and something an ice hockey goalie tries to block.".
Middle phase: I work clues in board order — "Element of a project that must be completed" → TASK; "Affix to the wall with a small pin" → TACK; "Complete absence, as of a quality" → LACK; "Small taste of an ice cream cone" → LICK; "Choose among options" → PICK.
Ordering phase: the valid middle chain is TASK → TACK → LACK → LICK → PICK. This permutation is the only valid one-letter chain for these answers.
I verify MASK to TASK — M→T at the first letter (MASK → TASK).
I verify TASK to TACK — S→C at the third letter (TASK → TACK).
I verify TACK to LACK — T→L at the first letter (TACK → LACK).
I verify LACK to LICK — A→I at the second letter (LACK → LICK).
I verify LICK to PICK — L→P at the first letter (LICK → PICK).
I verify PICK to PUCK — I→U at the second letter (PICK → PUCK).
Finished chain: MASK → TASK → TACK → LACK → LICK → PICK → PUCK. Combo ends MASK + PUCK clicked once ordering locked. Only one middle permutation forms a valid ladder from top to bottom — if ordering feels stuck, recheck a middle answer.
