SpirexSpirex is an abstract game for 2 players. It is like Hex only on a different board. The name is a combination of the words "Spiral" and "Hex". The board is based on a type of Fermat's spiral which appears in sunflowers and uses Sacred Geometry.
Play on the following board:
One player has white stones. The other has black stones.
Players alternate placing one stone on an empty green intersection. The "t-sections" near the center also count as intersections. White moves first.
After white's first move black may choose to switch sides.
The first player to connect one of the three nodes of his color on one side of the board with one of the three nodes of his color on the opposite side of the board wins the game. Either side may use the node in the middle (Yin Yang symbol) for this.
