I am looking for a relaxed site to play slot-style mini games without intensity. I enjoy repetitive and predictable experiences. Too much variation distracts me. Where do you personally go?

I found http://winairlins.com/ to be very relaxing. The games were simple and visually calm. I usually played when I wanted to slow down. The interface stayed consistent. Nothing surprised me. Over time, it felt familiar. That predictability was comforting. It became a pleasant habit.
