Welcome to Word Ladder, a word puzzle from Words Corner where you turn one word into another by changing one letter at a time. It sounds simple, but it takes a little planning. This guide covers the rules, a full example, and simple tactics for a quick 4-letter win.
What Is a Word Ladder?
A word ladder gives you a start word and a target word of the same length. Move from one to the other by changing exactly one letter per step, and make sure every word along the way is a real dictionary word. The target is visible from the start, so the challenge is choosing a good route. Lewis Carroll invented this puzzle in 1877 as “doublets.” At Words Corner, you can play a daily shared ladder or unlimited practice rounds.
The Core Rules of Word Ladder
Three rules matter most:
- The start and target words have the same length.
- Each step changes exactly one letter.
- Each new word must be a real dictionary word.
The game shows “par,” the fewest possible steps. You don’t have to hit par to succeed, but it gives you a useful target.
How to Play: A Beginner Walkthrough
- Open Word Ladder at wordscorner.com/word-ladder. No account is needed.

- Pick a 4-letter ladder — the classic, gentler way to start.
- Compare the start and target words.
- Tap a letter in the last word, then pick a replacement.
- The new word must be a real dictionary word.
- Continue until you reach the target, using as few steps as you can.
Every puzzle is checked in advance, so a solution always exists.
The COLD → WARM Example, Step by Step
The classic example from Words Corner is:
COLD → CORD → CARD → WARD → WARM
Change L to R to get CORD, change O to A to get CARD, change C to W to get WARD, and change D to M to get WARM. Each step alters exactly one letter, and every intermediate word is a real dictionary word. This takes four steps, so par for this ladder is four.
Tip: Work backward from the target, too. WARD is just one letter away from WARM, so once you reach WARD, the finish is close.
Simple Tactics for Your First 4-Letter Win
- Compare the start and target letters. Shared positions can stay constant throughout the ladder.
- Try vowel changes first. In the example, changing O to A produced the helpful bridge CARD.
- Use short, common words. CORD, CARD, WARD, and WARM are everyday words, making them easy to spot.
- If you’re stuck, change a consonant to a nearby one. Changing C to W turned CARD into WARD.
- Don’t aim for par the first time. Find any valid route first, then look for shortcuts.
For a five-minute win, keep it simple. See if a change makes a real word. If it does, use it; if not, try another letter. Wrong branches can be abandoned.
