Each player has 10 pieces: the 9 planets and the Sun. The aim of the game is to move your planets (including the Sun) to form triangle, quadrangle, and pentagon constellations with your opponent's planets. For each constellation formed, you may take one of your opponent's planets in that constellation. You win the game when you form a constellation with your opponent's Sun (a kind of checkmate), or when your own Sun gets to the center of the board. A similar game, 'Moneychase,' is played on the same board and pieces and rules are included for this second game. - BoardGameGeek
