Great games are the tools for ensuring that once a player visits a site, they return frequently. The first time a player opens a great game, they should be able to quickly establish how to play the game and they should be quickly rewarded for their efforts if not financially, then with aesthetics, positive reinforcement of wins and in-game excitement via visual and auditory stimulus. The combination of the ease of repeat play, combined with sufficient options to allow exploration of play styles not only maintains but expands the life of the gaming experience, and ensures that the player that has visited a gaming site returns again and again.
