Game Options

Q: How do visibility and entry requirements work?

Leaderboards and Tournaments gives developers the flexibility to group players in the way that works best for their game. Developers can simply define the attributes they’d like to use to filter which customers should be able to see a competition, and which should be able to enter. Attributes include, but are not limited to, the player’s location, device type, character level, type of character/car/deck they have equipped, possession of a specific consumable item, highest score, etc.

Q: What scores show up on the leaderboard?
The score that shows up on the leaderboard is set by the tournament organizer using the Leaderboards and Tournaments Console or the Leaderboards and Tournaments Tournament Organizer on Twitch. A game can support the default score value or a list of game stats. Tournament organizers can choose a leaderboard stat from this list when they create a tournament. For example, a game can provide a score value or pass in-game stats such as Points, Kills, Wins, or Coins. The tournament organizer can choose one of these as the leaderboard stat. Values of this stat determine player ranking on the leaderboard.
