I tackle Crossclimb Level 1 in three passes — middles first, ordering second, combo ends last. This 4-letter board runs WARM → … → WORK with combo clue "A hot day on the job".
Middle phase: I work clues in board order — "Bug in the garden" → WORM; "Unit of a sentence" → WORD; "Part of a hospital" → WARD; "Give a caution" → WARN; "Second form of WEAR" → WORN.
Ordering phase: the valid middle chain is WORM → WORD → WARD → WARN → WORN. Note: reverse order also steps one letter at a time, but only this orientation matches the stored top and bottom slots.
I verify WARM to WORM — A→O at the second letter (WARM → WORM).
I verify WORM to WORD — M→D at the fourth letter (WORM → WORD).
I verify WORD to WARD — O→A at the second letter (WORD → WARD).
I verify WARD to WARN — D→N at the fourth letter (WARD → WARN).
I verify WARN to WORN — A→O at the second letter (WARN → WORN).
I verify WORN to WORK — N→K at the fourth letter (WORN → WORK).
Finished chain: WARM → WORM → WORD → WARD → WARN → WORN → WORK. Combo ends WARM + WORK 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.
