Terms of use

Last updated 14 October 2026

These terms apply when you use Arbiter. By using it you accept them.

An unofficial fan project

Arbiter was created under Riot Games' "Legal Jibber Jabber" policy using assets owned by Riot Games. Riot Games does not endorse or sponsor this project.

Arbiter is a free fan project for Riftbound players and judges. It is not made, endorsed or sponsored by UVS Games.

Not an official rules source

Arbiter reproduces the official Riftbound documents, but it can be wrong, out of date or incomplete. The official documents always win, and at an event the judges there have the final word. Each rule page links to the official document it comes from.

No warranty

Arbiter is provided free and as it is, with no promise that it is correct, complete or always available. As far as the law allows, we are not responsible for any loss that comes from using it.

Using Arbiter fairly

Please don’t:

• send reports that are spam, abusive or not about Arbiter;
• send automated traffic to the Arbiter server or its content API that overloads it or gets in other people’s way;
• try to get into other people’s accounts, or into parts of the service that are not meant for you.

We may block a network address or close an account that does.

Accounts

An account is optional. You must be 13 or over to create one (or older, where local law sets a higher age). Keep your password to yourself.

You can delete your account at any time in Settings; that removes its data at once. We may close an account that breaks these terms. If we ever stop running Arbiter, we will try to give notice so you can download your data first.

Who owns the content

Riftbound, its rules, card names, card text and card art are © Riot Games. Riot Games and the respective owners keep all rights to their material. Arbiter uses it under Riot’s "Legal Jibber Jabber" policy and claims no ownership of it.

Takedown and rights requests

If you own material shown on Arbiter and want it changed or removed, write to hello@riftarbiter.com with the page’s address and what you would like done.

Privacy

What Arbiter keeps about you, and why, is in the privacy policy.

Changes to these terms

We may update these terms. The new version goes on this page with a new date, and using Arbiter after that means you accept it. Questions: hello@riftarbiter.com.
