Organizing Community Tournaments using Blizzard Games

Planning on organizing a community tournament using StarCraft® II, StarCraft, StarCraft: Brood War®, World of Warcraft®, Warcraft III: Reign of Chaos®, Warcraft III: The Frozen Throne®, Hearthstone™: Heroes of Warcraft™, Heroes of the Storm™ or Overwatch™? Follow these steps to make sure that your community tournament kicks off flawlessly.

Step 1: Find out if you need a license

In most cases, you don’t! You can organize and host many types of community tournaments without any further license from Blizzard subject to these conditions:

If a community tournament organizer follows the above conditions, the community tournament organizer may run his event without further license from Blizzard. A tournament that is being operated under the above license is neither officially supported nor endorsed by Blizzard and the community tournament organizer must notify the participants of this fact. The tournament license strictly means that Blizzard has given a user permission to run a community tournament on the service as long as these certain stipulations are met and the tournament organizer agrees to these Community Tournament Guidelines. It is the responsibility of the tournament organizer to prove the legitimacy of his tournament to potential players and spectators.

Blizzard may, in rare instances, revoke an organizer’s tournament license if the tournament promotes or represents anything contrary to Blizzard’s Core Values.

What if I want to run a tournament over the Maximum Prize Value?

That’s awesome! We’d love to work more closely with you to ensure the success of your tournament. For larger tournaments like this, we can often help promote your event in the appropriate region, or offer other assistance. That process starts with obtaining a tournament license from Blizzard. Head on over to our Tournament Submission Form to start your licensing process now. Approval time will vary; event tournament license approval can take up to four weeks, depending on the complexity and level of licensing required for the event.

What if I want to run a tournament that doesn’t comply with all of the above conditions?

Let’s discuss it. We’d like to work with you on running a tournament that fits your needs while also serving the needs of players and viewers. Start with the Tournament Submission Form,and we’ll be in contact to see how we can work together.

Step 2: Get Whitelisted

In order to ensure the safety and security of for all players, we have implemented mechanisms to detect and block specific IP addresses if too many connections are being made from a single source. This can occasionally cause problems for organized tournaments where many computers on a local network are all connected to the Internet using the same external IP address. Registering your tournament with Blizzard will allow us to add the IP addresses to the appropriate whitelist for the machines you intend to use for the duration of the tournament. If you’re running an on-site event that will have more than ten (10) people connecting at once from a limited range of IPs, send us an email with the subject Whitelist Request to and include detailed information about your event as well as your venue’s IP information.

Step 3: Ask us if you have questions!
