I'd like to recommend a game that I enjoy, and I'm sure some of you will enjoy it as well and even benefit from it. It's called Jigsaw Puzzle Dreams, and it's a puzzle game, as the name suggests. You can work on many of the available puzzles and even upload your own photos. This puzzle game has all of the features that puzzle gamers enjoy, such as rotating and moving, and provides a variety of options for creating puzzles ranging from easy to difficult.
Puzzle games, in my opinion, are one of the best side activities to strengthen your mental focus and ability to think, aside from meditation.
