excellent collection of solitaire game. great graphics. intuitive user interface, UI. Love the all the different challenge modes: daily, monthly, special events, and the star mode. Awesome upgrade from Windows 98 solitaire and freecell, LOL. Seriously good game. I had no qualms about $10/year to turn off the ads as well. ((2020 still great, even better, paid for another year of premium!!!!))
