Hemispheres - Duel Your Brain

By Pit Garbe

Open iTunes to buy and download apps.


Do you know math? Have you heard of color theory and know how to mix two colors? You think thats child's play?

Maybe you're right, but what about solving simple math problems while at the same time you have to mix two colors together? How long can you keep that up against the clock? The clock which is constantly getting faster!

One thing you should know right away. It's pretty hard! Your brain handles each of those tasks with one of its hemispheres. One is better fit to solve logical tasks, like math problems. The other is rather creative and will look at the colors for you.

The annoying little detail is, that your brain takes an awful lot of time to switch tasks. You'll be surprised how often you're seemingly just sitting there, waiting for your brain to get ready serving you. But the time keeps ticking!

You can only make two errors on each side. The game ends with the third error. The timer running out is an error as well.

→ Train your brain!
→ Compare to players around the world!
→ Try getting all the trophies!
→ Marvel at your brain reaching unthought of limits!
→ Don't be frustrated that it won't be easy at first. That's normal :)

Free Tip #1: Use two hands!

Free Tip #2: Using headphones lets you hear the stereo postion of the sounds. Can be quite helpful in intense situations.

(The game uses Localytics to analyse the user engagement, but participation is voluntary and not necessary! I just thought, I better let you know.)

Addictive... And good for your brain!

Such a simple game but not so easy to get a high score as the game speeds up as you go. One side of the screen has simple arithmetic and the other has a multiple choice for mixing two colours and you only have a few seconds to get it right as it fires straight on to the next set. Don't know if it's coincidence or not but I have felt a boost in general brainpower since I started playing this game! You apparently use both sides of your brain at the same time - normally I'm lucky to use one side of my brain at any time!!

Great Game!

The only brain game I have downloaded and the only game that uses both sides of your brain. It's a brilliant game and I highly recommend it.
