About Word Ladder
A word ladder transforms a start word into an end word by changing one letter at a time, with every intermediate step forming a valid word. Fill in the missing rungs.
Tips
- Work from both ends toward the middle.
- Vowel-heavy words offer more single-letter neighbors.
- Say candidate words aloud — valid English words often surface by sound.
FAQ
- Who invented word ladders?
- Lewis Carroll popularized them in 1877, calling the puzzle 'Doublets'.
