How do I get golden eggs?

A Gold Egg is received if you score high enough in the event you play. Some games rate your performance using 1/2/3 Stars, or Bronze/Silver/Gold Medals, or A/B/C/D/F Grades. Alphabear uses Silver/Gold Eggs. (We used to have Bronze Eggs, too, but currently none of the events award Bronze Eggs.)

This page shows how you can know the score requirements for a Gold Egg in a particular event.
