The SGN Link Exchange is implemented through use of the SGN Bar, as seen above. The bar contains links to SGN Games. The frequency at which a game appears in the bar is determined by how many clicks the game delivers to the bar. The more clicks a game gives, the more it appears in the bar and the more clicks it will then receive. The fewer clicks a game provides the less frequent it will appear in the bar.
To get the SGN Bar, a developer need only implement the SGN Hub API and make an API call. The SGN Bar is returned by the API. There are no restrictions based upon where you implement the bar in your game. However, since the number of clicks a game generates determines how many clicks the game will receive, a good placement is encouraged to ensure maximizing the benefit of the bar.
Please visit the API Client Libraries and API Documentation sections of this site for more information about implementing the bar.
