Word Ladder is a classic puzzle invented by Lewis Carroll in 1877. The rules are simple and the puzzles are satisfying: take a starting word, change one letter at a time, and reach a target word. Each step along the way has to be a real word.

CAT to DOG? CAT → COT → DOT → DOG. Three steps, each one a real word.

Where to find it

Go to Activities → Brain Games, and tap Word Ladder.

How to play

1. Tap Play.
2. You will see a starting word (like CAT) and a target word (like DOG).
3. Change one letter in the starting word to make a new real word.
4. Keep changing one letter at a time until you reach the target.
5. Each step must be a real English word. The game will tell you if it is not.

The rules

• Change one letter at a time. You cannot change two letters in the same step.
• Every step must be a real word. No made-up words, no abbreviations.
• You cannot rearrange the letters. Position matters. CAT to TAC is not a valid step, even though both are words in other contexts.
• The word length stays the same the whole way. If you start with 3 letters, every step has 3 letters.

What it trains

• Vocabulary. Short words in particular, which often get overlooked.
• Spelling. Because each step must be a real word, you notice how letters combine.
• Creative thinking. Finding the path requires trying possibilities you might not have considered.

How long a puzzle takes

Two to five minutes. Shorter ladders go faster. Longer ones (5 or 6 letter words) can take a bit more thought. Every puzzle has a solution.

How to solve a ladder

• Look at the target word. Which letters does it share with the starting word? Those letters can stay. The others need to change.
• Change the easiest letter first. If you can see a real word that is one letter away from the start and closer to the target, that is usually a good first step.
• Do not be afraid to try and back up. The game will tell you if your word is real. Just try.
• Short words are your friend. The puzzle usually wants you to go through common three-letter words like CAT, HAT, HOT, DOT, DOG.

If you get stuck

It gets easier with practice

This is one of those puzzles where you can feel the difference. After a week of playing, the same length ladders go noticeably faster.
