AppStore New Games We Love “It is fascinating as to why this game was made.” Pocketgamer.com 7 is considered to be a special number in many cultures around the planet. 7 days of creation, 7 seas and 7 sins. 7 notes in Indian music, Lucky 7 and harmony in China. 7 islands of Atlantis and most likely to be chosen as a favourite number by people around the world. Why are we so obsessed with this number? For thousands of years. What makes it so special? In 1956, George A. Miller concluded that we are able to hold, on average, 7 chunks of information (plus or minus two) in the short-term memory at one given time. Is it really our limit? With this game, you may be able to challenge this theory as well as your memory. In 7 pyramids you will find 200 memory challenges that will increase with each level. Can you really remember 7 chunks of information? How about 10?
