In Out (IO) Game
<< Back to Free Brain Games page


Play in Larger Window
  

This In Out brain teaser game doesn't come with instructions. Part of the puzzle is figuring out the rules! It's a brain workout before you even start playing.

Even I don't know how to play this game. If anyone figures it out, please send me an email using the "Contact Me" button at left.

This game obviously has something to do with electricity and circuits. But beyond that I'm completely puzzled.

UPDATE:  Several people have figured out this game and emailed me with an explanation. But I'm still not going to tell you. Figuring it out is half the fun, and half the mental workout, too!   :)
