The search engine giant Google is going update their Google Adsense product with a new standard sensitive ad category. The new Google Adsense inventory is a limited beta program which is supported in English only.
Google Adsense has stated in a message towards their Google Publishers that the social casino games are defined as simulated gambling games where there is no oppurtunity to win anything of value such as money or prizes. Standard sensitive categories are allowed by default in the Google Adsense program.
