Magic 8-Ball

How it works

The Magic 8-Ball uses the Web Crypto API (crypto.getRandomValues) to select one of the 20 classic responses at random. The original 20 answers are split evenly: 10 affirmative, 5 non-committal, and 5 negative.

Everything runs in your browser. Your questions are never sent anywhere, stored, or tracked.

Frequently asked questions

Does the answer depend on what I type in the question box?

No. The question field is only there to help you focus and read the reply in context. The answer is drawn at random and is completely independent of the text you enter, so asking the same question twice can give different results.

Are these the same answers as a real Magic 8-Ball?

Yes. This tool uses the classic set of 20 responses in their traditional split: 10 affirmative, 5 non-committal, and 5 negative. Nothing was added or removed.

Is every answer equally likely?

Yes. Answers are picked with the Web Crypto API using rejection sampling, so each of the 20 responses has an exactly equal chance. A simpler modulo approach would slightly favor some answers, so we avoid it.

Do I need an internet connection to use it?

Only to load the page the first time. The answers and randomness are generated locally, so once loaded the tool keeps working offline and never contacts a server.
