Frequently asked questions.

What is a word ladder?

A word ladder is a puzzle where you turn a start word into a finish word by changing exactly one letter at a time. Every step in between has to be a real word.

Do I need an account?

No. Word Ladder works with no sign-up and no login. Your progress and stats are saved locally on your device.

Is it free?

Yes. Word Ladder is completely free to play.

Does it work offline?

The word lists are bundled with the app, so solving a puzzle works without an internet connection. You'll need to be online to see the live leaderboard and submit your time.

Is there an Android version?

Not right now. Word Ladder is an iOS app only.

What is Computer Assist?

If you're stuck, Computer Assist shows the next best word after a short, optional ad, so you can keep the ladder moving without giving up on the puzzle.

How does the leaderboard work?

Once you finish the daily puzzle, your time is submitted to the global leaderboard so you can see how you rank against everyone else who solved it that day. No account is required to appear on it: you can pick a display name or keep an automatic one, and you can report any name you find offensive.

Can I replay the daily puzzle?

Each day's puzzle is a one-shot: once you complete it, a new one appears the next day. Random mode is there anytime you want more practice.
