Word Ladder tips and strategy
In a Word Ladder you turn a start word into a target word, changing one letter at a time, and every step must be a real word. You have six moves. Most ladders are solved by planning, not by trying words at random. This guide describes the habits that make a ladder easy to read.
1. Count the letters that differ
Compare the start and target letter by letter. If three of the four letters are different, you need at least three moves, because each move can only change one letter. That number is your starting estimate. With six moves available, you can afford a few detours, but not many.
2. Fix a letter that is already right for the target
When a move turns a letter into the one the target has in that position, you have made real progress. Prefer those moves when they are available. When none is available, you need a detour: a move that does not match the target yet, but opens up a better word next.
3. Work from both ends
Do not only think forwards. Look at the target and list the words one move away from it: change each letter in turn and see which results are real words. Then look for a word that is close to both your start word and one of those neighbours. Many ladders that look impossible from the front become short when you approach from the back.
4. Change the vowel to change direction
In four-letter words, the vowel is usually the most flexible letter. Switching it, for example CAMP → CAME, often unlocks a whole new family of words. If you are stuck, try each vowel in each position.
5. Avoid dead-end words
Some words have very few neighbours, which means few ways to leave them. A word like OXEN has only two one-letter neighbours in our dictionary, while a word like MAKE has many. Before you commit to a step, ask whether you could keep going from it. A step into a word with many neighbours keeps your options open.
6. Remember you cannot repeat a word
Going back to a word you have already used is not allowed, so you cannot simply undo a move that did not work out. Think one or two steps ahead before you type.
A worked example
Take LOVE to HATE.
- Compare the words:
LandH,OandA, andVandTdiffer; the finalEalready matches. That is three differences, so you might hope for three moves. - Try the direct route: fix each of the three letters in turn. Every order passes through a word our dictionary does not accept (such as
HOVE,LAVEorLOTE), so a three-move ladder does not exist. - The shortest ladder takes four moves and starts with a detour:
LOVE → LONEchangesVtoN, which is not a letter the target needs. After that every move fixes a letter:LONE → LANE(O → A),LANE → LATE(N → T) andLATE → HATE(L → H).
The lesson: the number of differing letters is a lower bound, not a promise. Another example, HEAD → HELD → HELL → TELL → TALL, takes exactly four moves because all four letters differ and every step lands on a letter the target needs.
