I find it soothing to do almost any well-defined task with well-defined progress (with bonus points if it's tactile). A lot of us have jobs where all of those properties are in short supply. Certainly most of my stress is due to uncertainty. My guess is that game works by giving you a nice well-defined task you can definitely accomplish.
You can also try paper planes, or origami in general. I find it's just enough challenge to get me to focus for a little bit. :)
