The present disclosure is directed to building games and methods of playing building games. The reservoir can be subjected to thermal energy in order to reduce the viscosity of the substance. Simultaneously, an external write enable signal XWE and an external address signal ADD are received, and a memory cell 1, in the memory core 6, corresponding to the received external address signal ADD is selected. An NMOS transistor may have a tensile stressor layer, and a PMOS transistor may have compressive stressor layer. Gasses or liquids may be introduced to the environmental cell through channels formed in either the puck, sample holder, or cell chamber.
