In preparation for the Rose-Hulman Undergraduate Mathematics Conference, "Turning the Lights Out in Three Dimensions was written and presented in the Spring of 1999, again under the direction of Dr. One year later, Jake extended the result to the three dimensional version, Lights Out Cube. Todd Feil in the fall of 1997 at DenisonUniversity. Jake Tawney completed "Turning the Lights Out with Linear Algebra"under the direction of Dr. We will present a complete solution to Lights Out Cube in a style similar to that used by Feil and Anderson however, a lack in certain mathematical conveniences of matrices present in the original Lights Out solution will complicate the process for the cube of lights. Again, the game presents the user with a configuration of lights, some off and some on, and the objective is to turn all the lights out. Thus, in Lights Out Cube, pressing any button will always result in the change of parity of five buttons, itself and its four neighbors. The parity-changing rule still applies, except this time if a light lies on the border of a face, pressing it will change all of its neighbors, including those on adjacent faces. Later, Tiger released its next version of the mind puzzle, Lights Out Cube, a cube in which the sides are three by three grids of lights. The object of the game is to get all of the lights turned off. Pressing a button results in a change of parity of that button and a change in parity of the north, south, east, and west neighbors of that light (if such neighbors exist). The original version, solved by means of Linear Algebra by Feil and Anderson in October 1998 is a five by five grid of lights.
Tiger electronics now has an entire Lights Out series.
