A random shuffled deck of 52-playing cards by Memoriad™ Software is shown to each competitor on the computer screen for each attempt. Each competitor is asked to memorize the same ordered deck of cards. The competitors try to commit the order of the cards to memory in memorization time.
During the memorization process, the cards can be looked at repeatedly and more than one card can be looked at simultaneously.
