In Dragons' Eggs, players use their treasure cards to bid on egg cards, and whoever has the most eggs at the end of the game wins. In more detail, each player starts with a hand of eleven numbered treasure cards and one ability card; the deck of egg cards is shuffled, then one card revealed. Each player plays one or two treasure cards from hand in turn, revealing one of the cards if they played two. Each player in turn draws an ability card, then plays or discards one ability card. They reveal and resolve these ability cards simultaneously, then see who wins the round and claims the egg card. A player can pass on bidding in a round by discarding one of the egg cards they've previously collected.
