20/20 Memory Challenge app for iPhone and iPad

Simple to use and addictive! Keep track of your hi-scores to see your memory improve. Choose from 10 subjects ranging from symbols and colours that test basic symbol memorising to more detailed and challenging themes that require memorising fine details. This game is designed to exercise your visual cortex. Up to 4 players can store their best scores and track their progress.

In theory, memories are stored in areas of the brain depending on the subject. Themes in this game exercise those areas of the brain where those memories are stored. As you progress, levels and themes get more difficult until the ultimate final level.

Early themes are basic symbols and later themes test fine visual details. There are 3 modes. Practice lets you try any theme on any difficulty level. Memory Mode allows you to remember each symbol once to test your memory. Memory Challenge mode is slightly different by adding gameplay elements such as luck and tactics! You are awarded Glimpse points which give the extra chances you need later on by testing your photographic memory. Regular exercising of the brain is good for you. You can even use this to test your ESP skills! . Do not be dis-heartened if your scores are poor at first as they should improve with practice.
