I have very similar preferences. I also don't like it when everything flashes, glitters and jumps — you get tired of it and you don't feel like playing anymore. It's important to me that everything is in its place, without unnecessary visual noise. That's exactly what I found on
https://www.instagram.com/flamezcasino/. The interface is so well thought out that even without registration you can understand how everything works. I figured out where everything was from the very first minute. Everything is intuitive — if you want slots, if you want tables, it's all in a couple of clicks. Not a single irritating element, everything is clean, calm and pleasant to the eye. This is exactly the case when the site does not interfere with the game, but helps.
