Frequently asked questions

Is Bible Duel free?

Yes. Every mode is free to play, and there are no ads.

Do I need an account?

No — you can play straight away as a guest, and your progress is saved on your device. A free account keeps your progress on every device, puts you on the leaderboard and lets you duel other players. When you sign up, your guest progress comes with you.

Which Bible translation do you use?

Verses are quoted from the Berean Standard Bible (BSB), a modern translation in the public domain. Every question is also checked against the King James Version, so the answer is right in both.

How are the questions checked?

There are 3,273 questions from all 66 books. Each one was checked against the Bible text: the answer must be stated in the verse it cites, every wrong option must really be wrong, and we avoid church traditions that aren't in the text and topics Christian traditions disagree on. See About.

I think a question is wrong. What do I do?

Tap Report under the verse after you answer, or use Feedback. We look at every report.

Can I play offline?

Yes. Once you've opened Bible Duel, solo games work without a connection. Your results are saved when you're back online. Duels need a connection.

Can I install it like an app?

Yes. On Android and computers, choose Install in the browser menu or on the home screen. On iPhone and iPad, open bibleduel.com in Safari, tap Share and then Add to Home Screen.

Is it suitable for children?

Yes, Bible Duel is family-friendly. Children under 13 should only create an account with a parent's permission — they can always play as a guest.

How do I delete my account?

Can my church or group use it?
