I won’t speak for everyone, since people are different and everyone has their own way to relax and deal with stress, but puzzles really work for me. It’s like I switch my focus to the process and don’t think about deadlines, problems, or whatever. I do jigsaw puzzles online. Pretty pictures, good quality, really nice to put together. Nothing lags, the site runs smoothly. They even have phone versions, so for me it’s a perfect setup.
