To trigger the free spins feature you’ll need to land five of any of the waitress symbols, in any combination, and this will reward you with a minimum of five free spins. The feature symbol is a waitress with a purple background, while the gold feature is a waitress with a green background. And here is where it gets a little bit confusing regarding the feature and gold feature symbols, as both are identifiable by a blonde waitress character, just with different background colours. The Bier Haus bonus round is essentially just free spins mode.
