ESP Test is a game for 8-bit Apple II's to test your "Extrasensory Perception." It was written using the 64K ProDOS version of Z-Basic from Zedcor, and should run on any 64K Apple II that can run ProDOS.
The program simulates using a deck of the standard ESP Cards (sometimes called Zener Cards) used by the parapsychologist J.B. Rhine in his classic studies of Extrasensory Perception. Each card has one of five different symbols on the face: Square, Circle, Cross, Star, or Waves. The back of a card is shown and you have to choose which of the five symbols is on the face. After you make your choice the face is shown to you and your percentage of correct guesses is tallied.
