Monarch is a light strategy game for 2-4 players that lasts 45 minutes. The primary mechanic is set collection; each of the sisters aims to assemble a court of Court Cards in order to prove her worth: wise advisors, exotic animals, and symbolic regalia. Each of these Court Cards provides crowns, and the sister whose court contains the most crowns at the end of the game becomes the Queen.
There are tricks to assembling a majestic court. Some cards don't work together well: the Astronomer is worth nothing if in a court with the Fireworks because he will be unable to see anything! Other cards work very well together: the Beastkeeper is worth more crowns for each animal she shares a court with.
