I tackle Crossclimb Level 16 in three passes — middles first, ordering second, combo ends last. This 4-letter board runs REST → … → FEED with combo clue "Evening meal after a break".
Middle phase: I work clues in board order — "Opinion when something is great" → BEST; "Hold up your pants" → BELT; "Defeat in a race" → BEAT; "Red root vegetable" → BEET; "They end at your ankles" → FEET.
Ordering phase: the valid middle chain is BEST → BELT → BEAT → BEET → FEET. Note: reverse order also steps one letter at a time, but only this orientation matches the stored top and bottom slots.
I verify REST to BEST — R→B at the first letter (REST → BEST).
I verify BEST to BELT — S→L at the third letter (BEST → BELT).
I verify BELT to BEAT — L→A at the third letter (BELT → BEAT).
I verify BEAT to BEET — A→E at the third letter (BEAT → BEET).
I verify BEET to FEET — B→F at the first letter (BEET → FEET).
I verify FEET to FEED — T→D at the fourth letter (FEET → FEED).
Finished chain: REST → BEST → BELT → BEAT → BEET → FEET → FEED. Combo ends REST + FEED clicked once ordering locked. The middle chain works in forward or reverse order — both orientations step one letter at a time, but only one matches the stored top and bottom slots.
