Description

From the listing uploaded by “split-store”.

The digit span test is used to measure working memory's number storage capacity. A series of numerical digits will be displayed, after which you'll be prompted to recall the sequence. After each successful attempt, the number of digits is increased by one. After each failed attempt, the number of digits is decreased by one, and a life is lost. After three lives are lost, the highest successful attempt will count as your digit span. The average score is 7 digits, but how will you do???
