Spaiji is an evolution of TAIJI that can be played with a Series: Shibumi set, as it uses a 4x4 holes board and balls in two colours (white and black). Rules: The 4x4 board starts empty. Two players, White and Black, take turns placing one ball of each colour adjacent to each other. The balls can be placed on board holes or on top of 2x2 platforms. Notice that you can place a ball on a hole and the other on a platform, as long as they touch each other. Aim: The player with the largest group of connected balls of his/her colour when the pyramid is full wins. In case of a tie, the second player wins. Variant for beginners: Consider only visible balls for scoring (not the 5 hidden ones).
