Stereogram Mysteries 3D is a game developed by TAKAHIRO AYA that allows players to test their ability to perceive stereograms. Stereograms are two-dimensional images that, when viewed correctly, create a three-dimensional impression. The game features two types of stereograms: drawn diagrams and random dot stereograms.

In the game, players must read the number that pops up on the stereogram and select the corresponding number at the bottom. They must also tap the correct color as quickly as possible. The game score counts down, so players must tap the correct answers before the score reaches zero. The remaining game score is added to the total score.

Stereogram Mysteries 3D offers three levels of difficulty: Easy, Normal, and Hard. In Easy mode, players have 20 seconds to tap the correct answer, and 1-10 problems appear. In Normal mode, players also have 20 seconds to tap the correct answer, but 1-25 problems appear. Hard mode challenges players to tap the correct answer within 15 seconds, with 1-25 problems and no guide to match the perspective.

Stereogram Mysteries 3D is a free game that provides an entertaining and challenging experience for those interested in stereograms. Give it a try and test your stereogram perception skills!
