In this two-player abstract strategy game, six towers are assembled from square tiles of alternating colors. Players first select three towers each; the player who takes the half tile becomes black and inverts their towers so each player controls one color.
Players then take turns unfolding towers across a shared field, with placement and rearrangement rules governing how stacked tiles spread. After all towers have been unfolded, the visible territory of each color is counted from above; the player with more territory wins.
