I usually mute the sounds while playing the games because it gets pretty annoying for a long session when you just hearing the same sound over and over again. And it is true to an extent that sounds can manipulate the brain and can urge for more but it's more common at young age, like kids and adolescents not for an adult but to gamble legally, you need to be an adult of age over 18+. What I will say is about the animations that does the same or even more effectively than sound but when you mute the effect can be negligible with just the animation.
