## What is StereoNinja?

StereoNinja is a game to see how many autostereograms (hidden 3D images similar to those in the "Magic-Eye" book series) you can identify in 30 seconds, saving your scores along the way.

The hidden images in this game are simpler than typical "Magic-Eye" images: They are all capital letters in the English Alphabet, and they are all hidden within patterns of random-colored dots.

Become a "Ninja" at viewing autostereograms by using the game to improve your speed at finding the hidden 3d images. 

If you're not able to see autostereograms quickly, don't worry: You can use the game's practice mode to study 6 sample images with answer keys at your own pace!

In the next version of the game, players will be able to upload and share their scores.

### 5/5 — Awesome!

*2013-01-23*

Love it. 30 is my best. Agreed the refocusing is the most difficult playing solo. If someone could just make it for PC so we can enter using a keyboard scores would be in the 50-60 range.

### 4/5 — Surprisingly fun

*2011-03-23*

I really didn't expect to be able to do this on an iPhone screen, but picked it up in only a few tries. At this point, refocusing to see the answer buttons takes the most time. 17 is my best so far.

### 4/5 — Cute, fun

*2011-03-23*

I thought I was terrible at those Magic Eyes, but after a few rounds I was able to see them almost instantly. This game is a fun way to challenge your eyes.
