Similar to the game Simon, Shocking Memory has eight panels instead of four and you get shocked if you make a mistake. This game is not intended for small children or persons with heart conditions. From the publisher's website: Put your memory to the test. Repeat the sequence of lights and sounds. Each round gets a little longer and harder. If you can't remember the sequence; thats too bad, we're so sad...ouch! With three speeds even the best players will be sweating.
