Found on Instagram, by flickeringfandom. This is a game more than a challenge. Only series books count, but they can be of any length. The number of the book in the series is where it goes in the stack; if the number is double digit it can be used as the straight number or as the sum of the digits. Numbers can also be added to complete a row (2+1=3; 2+2+1+1=6). Rows do not have to be completed in order, but only complete rows count towards the highest number score.
