Invertris is a version of the Tetris game in which gravity is inverted. The game pieces fall upwards rather than downwards and players must clear lines at the top of the gameboard to prevent the pile from accumulating and reaching the bottom. This experiment takes place across several sessions; after completing the population study participants will return to the lab for 3 additional sessions each spaced at least two days apart. In addition to any extra credit possibly offered by your class professor participants will receive $30 compensation.
