Frequently Asked Questions
What is a Word Chain Solver?
A Word Chain Solver helps with two puzzle types: word ladders (transform one word into another by changing one letter at a time) and last-letter chains (each new word must start with the previous word's final letter).
How does word ladder mode work?
Enter a start word and end word of equal length. The tool searches for the shortest path where each step is a valid dictionary word differing by exactly one letter from the previous step.
Is this the same as Word Guess Solver?
No. Word Guess Solver filters words for Wordle-style green, yellow, and gray tile clues. Word Chain Solver finds paths between two words or suggests chain continuations.
Why does my word ladder show no path?
Some word pairs have no valid ladder within the dictionary, or one of the words may be missing from the word list. Try synonyms or shorter words (4–6 letters work best).
Is my text stored or sent anywhere?
No. All solving runs entirely in your browser.
Is this tool free and does it work on mobile?
Yes on both counts. The Word Chain Solver on draft21 is completely free with no sign-up required and works on all devices.
