In each turn, the active player chooses a blue die and rolls it with five orange dice, then all players use the actions on the dice to create their constellation, invite aliens to visit their creation, and discover nearby wormholes. When a player completes their constellation, they continue to create another constellation. When a constellation is completed, the player outlines and scores their constellation and then scores any unique alien visitors. When one or more players have completed two constellations at the end of a round, the game ends. Players score their incomplete constellation if any and score any wormholes they have discovered. The player with the most points wins the game. In case of a tie, players share the win.
