Can I use Rebet if I travel out of California?

Rebet checks where your phone is, not where you live. If you're physically in a state where Rebet operates, you can sign up and play there, subject to Rebet's terms. It won't work once you're back in California.

What can I use instead of Rebet in California?

Is Rebet a sportsbook?

Rebet is a social sweepstakes-style sports app, not a state-licensed sportsbook and not a CFTC-regulated exchange. That's why its state map differs from both.

Why Rebet isn't in California

Rebet runs on a social sweepstakes model. A number of states restrict or don't allow that model for sports, so Rebet doesn't operate there. The CFTC-regulated exchanges listed above run on a different, federal framework, which is why they are available in more states (their legal status is being tested in court; see our legal guide).

If you're travelling

Rebet checks where your phone is. In a state where it operates you can sign up and play, subject to its terms. See every state where Rebet is available.
