Since Windows 8.1 no longer offers the free, simple games, I wanted something that did not demand a sign in or membership just to play a quick game of solitaire. This is it! All-in-One offers 14 different solitaire games (most I have never heard of before). Each one has a brief intro to explain the rules & goal, plus a link to a YouTube video if you want more instruction. The games themselves are colorful and cheerful, with large, easy-to-see cards. Best $2 purchase of the year. Enjoy!
