Definition

A game mode is an object featuring a set of parameters which define the configuration and the behavior of a match. The set of parameters defined on a game mode can further be edited at competition creation time, or voted upon during a match’s voting phase. The final set of parameters will eventually be passed to the game during the Match Configuration call, inside the game_custom_data field of the request.

Example:
