In Everdell Duo, you either compete against your single opponent or play co-operatively with another player to earn the most points. You accomplish this by placing workers to gather resources, then use those resources to play cards face up in front of you, creating your own woodland city.
Cards may be played from your hand or from the face-up area on the board called the meadow. However, only cards touching the sun or moon token may be played from the meadow, and players move these tokens each time they perform a turn. Therefore, planning for and timing which cards you play is critical.
