Stratos Spheres

Stratos Spheres is a the classic four-in-a-row game without the restrictions of the 2D board. In fact, there's no board at all because you build the game as you go. Using three-dimensional spheres, each player tries to connect four of their spheres in a row while stopping their competitor from doing the same. The first to connect four spheres horizontally, vertically, or diagonally wins.
