How the solver works
Think of every 4-letter word as a dot, with a line between any two words that differ by exactly one letter. A word ladder is a path along those lines. The solver runs a breadth-first search outward from your target word, which guarantees the path it finds is as short as possible. When several shortest ladders exist, it picks the one whose words are the most familiar.
It uses the same dictionary as Poople: 3,898 four-letter words from a Scrabble-grade list. Wondering why a word isn't allowed? Ask the word checker.
Reading the results
- Compare routes lists up to six different shortest ladders, friendliest first, each tagged with how many rare words it uses.
- Rare words are accepted but not everyday English — Poople never uses them for par or hints. Switch to Everyday words only to avoid them; the solver tells you if that makes the ladder longer.
- Branches under each step show every next word that still keeps the ladder shortest, out of all the words one letter away. Tap one to reroute through it.
- Play this ladder turns the pair into a custom ladder you can play and share.
Classic word ladders
HEAD → TAIL (5 steps)
The example Lewis Carroll used to introduce Doublets in Vanity Fair, 1879.
FOUR → FIVE (7 steps)
One of Carroll's original puzzles: “Raise FOUR to FIVE.”
POOR → RICH (7 steps)
Another Carroll original: “Turn POOR into RICH.”
COLD → WARM (4 steps)
A puzzle-book favorite.
Word ladder tips
- Count the letters that differ between start and goal: that's the minimum number of steps.
- When a direct swap doesn't make a word, look for a "bridge" vowel change that opens new options.
- Work backwards from the goal — its neighbors are often the real bottleneck.
