I am now on break. With the extra time, I wanted to continue to exercise my mind, but I wanted to do so in a jovial way. This came up with Divisors!, a game we created that helped with these skills while also looking at factors and mutliples of numbers. Today, instead of creating a new game, we will revisit a classic. In particular, Lights Out is a game where the goal is to turn all the lights out. Instead of just pushing the lights that are on, when you do press on a light, it will turn on those around that are off, and turn off those around that are on. This helps keep the mind working out patterns, keeping track of multiple steps at a time and is just fun. Can you determine which lights need to be hit in order to turn all the lights out?
Lights out was originally a hand-held game by Tiger. Below is a link to Amazon's offerings of the game (3rd party sellers only). You can also find different versions of the game (along with solvers) many places on-line. You can also find more on the theory of the game on Wolfram Mathworld.
