It looks same with me, on me personally love to gamble while playing games as well. But on me is a playing Clash Royale on the Bluestack app on PC. Other than that when i gamble i often open youtube and play a music who i liked, so it feels more relaxed when gambling and affect the brain to be optimistic thinking in gambling.
Listening to music helps you to think better ? News to me.
I always prefer pin drop silent so that I can focus on my strategies. Sometimes after setting up all the required things with my auto dicing, I prefer to go for having snacks while watching how my profits goes up and down.
Once we all set with auto dicing, it is very much similar to watching a thriller movie that is the reason I guess I'm going for popcorn to enjoy the most.
