Microsoft Solitare Collection gives you 5 different types of games to challenge and sometimes frustrate your skills. With daily challenge boards, cumulative awards and 4 skill levels to choose from you can easily spend hours without getting bored. Highly addictive to the dedicated solitare fan! One complaint is with the ads which appear before starting some games. I don't mind watching these in order to pay for free play but sometimes they don't start correctly - consequently neither can I!
