No settings other than you can “change gravity” and there re gaps between the “metal balls” so it doesn’t even work like you want it to. No sound control - totally overrides the sound no matter what. Just annoying that it doesn’t work as expected, and no “lite” version to find out BEFORE you buy. You would think it would at least be worth the 99cents, right and kind of work like a real newton’s cradle without gaps between everything. Maybe they had a defective model they started out with. Don’t get me wrong - I think they probably put a fair amount of effort into this product, and it is colorful, but overall very much lacking. Almost gave it two stars and decided it wasn’t really worth two stars.
