Crossclimb is LinkedIn's word ladder puzzle: you transform a start word into an end word by changing exactly one letter at each step, and every rung of the ladder must be a valid word. Crossword-style clues accompany the rungs to keep you oriented. Word ladders are one of the oldest puzzle forms in existence — Lewis Carroll invented them in the 1870s — and the techniques that work today are the ones that have survived a century and a half.
The rules
- Start word and end word are the same length.
- Each step changes exactly one letter — no adding, removing, or rearranging.
- Every intermediate word must be a valid English word.
- Crossword-style clues describe the rungs and help you confirm each step.
A real example ladder: SAID → LAID → LAND → LANE → CANE → CONE → DONE. Notice how each rung changes a single letter, and how the ladder "pivots" — it holds some letters stable while others rotate.
Technique 1: Work from both ends
The biggest speed win. Beginners climb forward from the start word and get lost in branching possibilities. Instead:
- From the start word, note which letters need to become which letters in the end word.
- From the end word, work backwards one or two steps.
- Meet in the middle, where the two halves have far fewer cells of distance to bridge.
A ladder of six or seven rungs usually splits cleanly into two three-step halves.
Technique 2: Change the rarest-constraint letter first
Look at the letters that differ between start and end. If one position must change from S to D, and very few words fit _AID patterns, resolve that position first. Positions with many candidate words can wait; positions with few candidates decide the shape of the ladder.
Technique 3: Use pivot words
A pivot word shares letters with both halves of the journey. In SAID → DONE, words like LAID and LAND act as pivots: they keep most letters stable while unlocking the next change. When stuck, ask: what common word differs from my current rung by exactly one letter and also sits closer to the target's letter profile?
Technique 4: Let the clues verify, not lead
The crossword clues describe the rung words, not the route. Use them as confirmation: if your candidate rung does not match its clue, the rung is wrong — do not bend the clue to fit. Matching rungs to clues is also a great way to unstuck: a clue like "Opposite of hot" instantly identifies a rung even when you have not found the ladder path to it.
Technique 5: Common letter-swap families
Some letter families appear constantly in ladders and are worth memorizing:
- Vowel swaps: CANE → CONE
- Endings: LAND → LANE (D→E), CONE → DONE (C→D)
- Common prefixes/heads: SAID → LAID (S→L)
Recognizing a family tells you the one-letter move without searching.
When you hit a dead end
A dead end means one of your rungs locked in a letter that the rest of the ladder cannot use. Retrace to the last rung where you had a genuine alternative and try the other branch. Because the clues pin down each rung's meaning, retracing is cheap: you always know which rungs are already correct.
Practice
Crossclimb publishes one ladder per day, and ladders vary between gentle (five rungs, common words) and sharp (long pivots, unusual vocabulary). Reviewing solved ladders is genuinely instructive — each one shows a route through word-space you can reuse. Our daily Crossclimb answer page shows the full ladder with its clues, and the archives keep every past puzzle for drilling.
From both ends, rarest letter first — the ladder solves itself.
