Every week, Gamasutra rounds up the top-grossing iPhone, iPod Touch and iPad applications, as current that day in the iTunes App Store. This week's U.S. revenue charts see Draw Something and Galaxy Empire earning top iPhone sales, while Slotomania HD and Sky Gamblers emerge as big sellers on the iPad.
These charts allow end users to see who is making the most money on the App Store that day. It differs significantly from the Top 10 Games chart, which is ranked by sales, and therefore is dominated by lower-priced titles that sell more copies.
Data comes courtesy of Apple's public sales information. All titles in the App Store's "Games" category are considered in chart rankings.
Paid and ad-supported versions of OMGPOP's hit social drawing title Draw Something lead the App Store's revenue chart for the second week in a row, outperforming Poker by Zynga and Tap4Fun's interplanetary colonization game Galaxy Empire.
Backflip's DragonVale drops to sixth place after finishing third last week, meanwhile, as Sega's Kingdom Conquest continues to generate steady microtransaction sales at tenth.
