# Standard

To launch a game, the Operator must call the [Game API](/integration/launch-game/standard/game-api.md).

THNDR responds with an HTML page that should be displayed on the Operator’s website.

\
The Game API URL can be loaded in either:

* an iFrame (recommended), or
* a full-page redirect.

Once the game is displayed, THNDR sends a server-to-server [Authenticate Users](/integration/launch-game/custom/authenticate-users.md) request to the Operator’s platform. This request validates that the player session and related information are correct.
