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!   :)

Lumosity brain trainingFOR BEST RESULTS:  The In/Out Game is a lot of fun, but as a brain training tool it is limited. If you really want to improve your brain, consider joining the Lumosity brain training service. I'm a subscriber to Lumosity, and I use it every day.

What it is.  Lumosity provides subscribers with online access to fun, scientifically designed games that increase brain power. Each game trains a different skill such as concentration, math ability, or short-term memory. Playing these games a few minutes per day helps your brain grow stronger.

My daily session consists of four or five games and takes about 10 minutes to complete. The games are selected for me automatically and change every day. It's an enjoyable, quick way for me to keep my brain sharp.

Get It Free.  If you want to try Lumosity, sign up for the 14-day free trial. That way you can find out (without it costing you anything) whether Lumosity brain training is right for you.
