Trism developer Steve Demeter revealed at a conference that he had generated $250,000 in income from his popular iPhone game since its launch on July 11th.
Trism is a gravity based puzzler which generated some press ahead of the App Store launch.
Trism presents the player with a playifeld populated by colorful, triangular tiles or trisms. The rows of trisms can be slid in six different directions (thanks to their triangluar shape) in order to achieve a match of three or more like-colored pieces. When a match is made, the like trisms disappear and surrounding trisms fall in to fill their place in the direction of gravity.
Trism is available from the App Store for $4.99. At that price, Trism would have had to have sold over 71,000 copies to generate that level of income, or an average of almost 1200 copies a day.
