Practice the skill of Precognition! Find out if your ESP ability is typical, or above average!
Simply click the card that you predict will be moved by The ESP Training Machine. If you're right, your skill percentage will increase, if you're wrong, your percentage will drop. After an extended number of attempts, a person with a hit percentage over 20% could be considered to have ESP!
A context menu should be shown when right-clicking or, on touch devices, long-pressing in the game. This menu especially allows to play in full screen and control the volume.
