StelliumStellium is a game in which players are architects of the universe just after its creation. They have to draw celestial bodies from a bag (represented by marbles with different textures, so they can try to pick the one they are looking for) and place them on the universe to complete contracts. Each type of celestial body has an effect on the universe, e. g., the comet takes the place of another one and "pushes them in line".
