Keep banquet plates spinning along a wedding table. Arc-swipe the rim in one direction—taps do nothing. Arc length and smoothness refill spin; reverse arcs brake badly. Green, amber, and red rims show stability; ignore amber and red drops smash satisfaction. End-of-song satisfaction is the main score; zero drops unlock a perfect feast badge. Camera focuses the active plate as oily cloth and waiter bumps intensify.
Banquet arc-spin plates—no taps—guest satisfaction fed by stable rotation speed.
