Players take turns placing cards in a grid to create an ever-expanding galaxy. Players score points based on connecting stars to form constellations, nebulas, and black holes. Depending on which combination of scoring cards are in play, players can score points in different ways for each galaxy card played: Stacking black holes on top of each other scores increasingly more points (1 black hole scores 1 point, 2 stacked scores 3 points, and 3 stacked scores 5 points and forms a supermassive black hole) Each connection vertex of a constellation formed by playing a card earns 1 point Each matching star in constellation chains scores 1 point Each quadrant of a nebula added to or created by a card earns 1 point Meteoroids score 1 point per nebula they go through and 2 points when they enter a black hole The game ends when the last galaxy card is drawn. The player with the most points wins.
