The 4 distinct modules of Yin-Yang can be combined at will for a brand-new gameplay experience of Chakra. The first module introduces new strategic opportunities with the white crystals. They allow you to increase the speed and flow of energies by temporarily harmonizing Chakras. By combining them with negative energies, you will gain Yin-Yang tokens, an additional source of plenitude. The second module and its harmonization bonuses will speed up the game and make every Chakra attractive, while the third module will have you race to achieve your objectives, forcing you to make difficult choices and increasing interaction. The last module will then require good timing to benefit the most from the available special abilities. -description from publisher
