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.
