Installed this game the day I got my phone and have been playing it every day since(10 days at time of this post). No problems with install or slow play! Simple game but very entertaining. I find I pick up my phone and can end up playing for hours and usually play after I go to bed, for "just a few hands to unwind"! :) Great job! I recommend to anyone!

Excellent graphics, Excellent features (basic), Excellent game. Install was smooth and flawless. Hust click and it begins to download no drag and drop here and there. Does not install into the correct folder (games) one of my pet pevs. No hang up, starts and stops perfect. Liked it so much I downloaded it to my girlfriends pda as well. :) A+ to the author. There is a games folder for a reason. Is there a way to make it run in that folder so its not in the general programs screen?
