Some implementations relate to methods, systems, and a computing device to generate predicted scores for games based on gameplay duration. In some implementations, a method includes obtaining game session data that includes a respective session duration for each game session of a plurality of game sessions, each game session associated with a respective game and a respective game player. The method further includes grouping the plurality of games game clusters based on the game session data, each game cluster including one or more of the games such that no game is in more than one cluster. The method further includes generating a predicted score for one or more of the games and identifying at least one game as a high quality game based on the predicted score. In some implementations, generating the predicted store includes determining a distance between each game and the decision boundary.
