Unavailable demo, when i open the game, a click on any card cause display of pop up for buy the game ! Sorry but 29.95 $ for 23 games is too much expansive. "Soliaire till dawn" of Semicolon for example cost only 24.95 $ for more of 100 games, with a better quality of graphism and other. Who would buy this play? Not me, it is certain!
