Load a game from the OpenSpiel library.

Parameters:

  • game_name (str) – The short name of the OpenSpiel game (e.g. "matrix_rps", "tiny_hanabi"). Passed directly to pyspiel.load_game.

  • params (dict, optional) – Game parameters forwarded to pyspiel.load_game (e.g. {"players": 2, "coins": 3, "fields": 2} for "blotto"). See the OpenSpiel game list for available parameters per game.

Returns:

The loaded game.

Return type:

gbt.Game

Raises:

  • ImportError – If open_spiel is not installed.

  • ValueError – If the game’s dynamics type is not supported for export, or if the format exporter raises an error for this specific game.

  • Other exceptions from pyspiel.load_game propagate directly. – For example, pyspiel.SpielError is raised for unknown game names or invalid/missing parameters.
