The idea of Schrodinger's Rat is to complete experiments and save as many rats as you can. To do this, player use the accelerometer of the iPhone or iPod Touch to maneuver a chalk ball through a maze. The goal is simple: navigate the ball from the start point to the end in the allotted time. Time is limited by a Geiger counter, which acts as a linear timer that steadily counts down as you're working your chalk ball through the maze. There are a variety of power ups and other objects that can both help and interfere with your progress, including a power up that resets the Geiger counter.
