Sixth is the next evolution of chess! The rules are simple: Your goal is to build a tower of six or more disks with your color on top. On your turn, you will either start a new tower by adding a piece to the board, or capture an existing tower by moving another in play. The twist is that each tower moves like a different chess piece, based on the number of disks in that tower. This captivating new abstract strategy game is easy to learn, but full of subtle complexity. It will challenge and engage newcomers and chess masters alike.
