    #  The Game service allows Game, User, Score and ScoreBoard Management on the Cloud.
    #  The service allows Game Developer to create a Game and then do in Game Scoring using the
    #  Score service. It also allows to maintain a Scoreboard across game sessions using the ScoreBoard
    #  service. One can query for average or highest score for user for a Game and highest and average score across users
    #  for a Game. It also gives ranking of the user against other users for a particular game.
    #  The Reward and RewardPoints allows the Game Developer to assign rewards to a user and redeem the rewards.
    #
    #  E.g. One can give Swords or Energy etc.
    #  The services Game, Score, ScoreBoard, Reward, RewardPoints can be used in Conjunction for complete Game Scoring and Reward
    #  Management.
