The social platform Tango offers its users to play the game Words With Friends by Zynga.
Invitations to fight in a war of words with Words With Friends, sent via the Tango messenger, will be displayed as messages inside the platform. The players who accepted the challenge will be sent to the application if it is installed, or to the market if not.
The approach to promoting games and entertainment services through messaging systems has proven itself well in Asia. The strength of such platforms lies in the extremely high virality that they provide to their games. In the western market, Tango went the furthest in this direction. Games on this site are offered by Gameloft and other companies.
