Goal
Change the start word into the target word one letter at a time.
Rules
- Each new word must be the same length.
- You may change only one letter per move.
- Every word must be a real dictionary word.
- You win when your ladder reaches the target word.
Example
COLD → CORD → CARD → WARD → WARM
Strategy
- Look at which letters differ between the current word and the target.
- Try changing one mismatched letter first.
- If that word is not valid, change a different letter temporarily.
- Sometimes you must move away from the target before getting closer.
