The Book Tower Challenge is a tag/challenge created by joelBOOKS. In the challenge, the person must collect 20 books in a certain time limit and then rearrange them in alphabetically order. The original time limit was 1 minute and 30 seconds to collect the books then 1 minute to rearrange them. However, polandbananasBOOKS (Christine) changed the rules in her video to completing the whole challenge in 3 minutes which many booktubers follow.
