I do at least one JigsawPuzzle every day...free, fully customizable as to # of pieces, shape/ sized them, rotation or not, background colorr, etc etc etc, relaxing, beautiful & when you complete one, the piece-lines disappear & it goes 3D. Try Jigsaw Daily or Jigsaw Epic by Kristanix.

I play pool. That's it.

I don't know if "Water Splash" is available on Kindle, but it's a really fun game. I also play backgammon and Uno, both of which have team play available. ... Water Splash looks like an easy kid's game, but give it a chance. It has more than 2,000 levels and I've been stuck on Level 563 for weeks. ... Also, there are some cheats / hacks I will share if you're interested.

I have Scrabble on my Android. It's the only game I'll put on a portable device. I can adjust the settings to play with the computer or with other players, and also adjust the difficulty level. I like how it makes me use my mind and helps expand my vocabulary.

The only one I ever played was spot the difference. When the girls were small we could break records on how fast we could do it. I don't know if it's still out.
