Objects in space have varying sizes ranging from planets all the way to galaxies. Players shuffle the cards and divide up the cards evenly. Without looking at the cards, players draw cards from their stacks and place them in the center. Using the categories of size outlined in Guide to Objects Card, players gain more cards if their card is “bigger” than their opponent’s. For instance, player 1 places a star cluster card, while player 2 places a planetary nebula card. Player 1 would win the round because star clusters are larger than planetary nebulae.
