About
Stereograms (3D images) use optical illusions to reveal hidden 3D pictures — and that's what makes them so fun. The problem with fixed patterns, though, is that you end up memorizing the answers. This app turns it into a quiz — guess the hidden letters inside each stereogram. Every round is randomized, so you'll never know the answer in advance. A great way to take a break when you are tired from your phone or computer.
