Enter the room with the game in progress

Options

How can I check if the master has already started the room, and send new players straight into the game?

I'm doing this for all players after the lobby goes into the game.

  [PunRPC]
  public void Game(string name)
  {
    PhotonNetwork.LoadLevel(name);
  }

And to enter the lobby

  public void JoinRoom(string nameRoom)
  {
    PhotonNetwork.JoinRoom(nameRoom);
  }

But how can I know if the master has already started the room? To send the player straight into the game rather than the lobby?
