There are better odds at a real casino and if you do purchase extra coins have no fear they will make sure they don't last. I've played this on and off and before you comment about free coins don't. They won't get you to advance. Nice try. Would be cool app if there was real money involved other than the players money. Your all too greedy. If your planning on installing this app don't because if you like the game you will have to spend a lot to play.
