Tell Rain Man what your birthdate is, and he can instantly tell you what day of the week you were born. To get a taste of one of the amazing memory feats Kim Peek can perform, click here.

Timed Memory Test - During each trial, random letters will be shown on the screen. After a few seconds, the text will disappear and you will be asked to write down the letters you were shown (the letters must be written in the sequence presented). Starting with one letter, a new group of random digits is displayed after each time you correctly remember the letters displayed. After each successive trial, the text will be increased in length.

Card Counter - Same rules as the 'Timed Memory Test', but this time you will be asked to memorize a sequence of playing cards. Good luck!

Face-off - A fun and silly game. To win, memorize the features of the face shown and rebuild the face from memory.

Flip & Match - Based on the classic card game, try to find all the matching cards in the least amount of moves. The trick? All the cards are placed face down and you're only allowed to flip over two cards at a time. Use your memory to remember what cards you have already flipped over and image appeared.
