As my mother is in her high 80's I bought her a computer a few years back and installed a bunch of jigsaw puzzles on it for her to wile her hours. Since then I found a digest that puts out up to 10 puzzles a day. I download these daily or every few days as they come into my email listing. I'm working on year 2012 so you can see I haven't kept up with them but they do waste a few minutes/hours of my time when I do work them. My mother has enjoyed her time putting them together all these years and I continue to add new ones to her computer to keep her busy. She has no hobbies and doesn't want any hobbies other than to waste her time playing her puzzles. Whatever works for her.
