Tournaments are what holds everything together

In our data Tournaments are the umbrellas that hold and group all Series and Matches together. To do this in a structured way, there are two additional concepts that we use called Stage and Substage, which we'll get into more below. In addition to just grouping, Tournaments also hold a lot of data about the Tournament itself such as where it is played, who will be casting it, prize pools etc. For the full rundown you can look in the API reference.


Stages are, as of now, only a grouping of Substages. The only data they hold is a name that describes itself in the context of the Tournament.


Substages, like Stages, also have a name element and groups Series together. Each Substage also have a type that dictates how those Series are played out. The types can be:


This is the most common Substage type and means that the Series are played in a round robin or swiss format. Groups are usually played over a longer period of time and participating competitors earn points based on how well they play.

Single Elimination Bracket

Single elimination (SE) brackets are the simplest type of, what is sometimes refereed to as a, knockout bracket. A SE bracket is at its core a tree structure in which the competitors compete and eliminate (or knockout) half of the participating competitors at each round of the tree. Typically all competitors start out in the first round (say the quarterfinals) and compete to reach, and win, the grand final. However, it is not entirely uncommon that some competitors are seeded to a later stage of the bracket, leaving some of the earlier rounds in the bracket partially unplayed.

Double Elimination Bracket

Double elimination (DE) brackets are basically the the same as a SE bracket but with an additional lower or losers bracket. What this means is that, unlike SE brackets where a competitor is eliminated as soon as it loses one Series, a competitor that loses a Series in a DE bracket gets another opportunity to get to the finals through the lower bracket. In effect all competitors must loose two Series to be eliminated from a DE bracket.

GSL Bracket

GSL brackets are a special variant of DE brackets used in qualification Substages. As you can hear from the name they originated in the Starcraft scene and are by many considered the most fair qualification method. In practice they are a DE bracket starting at the semifinals where the competitors who would normally reach the grand final, qualify onwards instead.

Bracket Coordinates

For you, as an API user, to be able to draw up fancy looking brackets we have devised a coordinate system that places Series in different locations in a bracket (and also tells you what to call them). Bracket coordinates come in a JSON format, which you read more closely about under BracketPosition in the resources, it looks like this:

  "part": "UB",
  "col": 2,
  "offset": 4
