Pop Sugar's reading challenge gives you 52 topics - one for each week of the year - although the last 12 are considered "Advanced".  To be true to the spirit of the game you should have a different book for each category, even though a lot of books could check the box for multiple ones. They offer a download version of the list.

 

Book Riot's Read Harder 2017 Challenge overlaps with Pop Sugar's list in a few places, but it's shorter. There are 24 topics. Similar to Pop Sugar, the last six are considered the "Advanced" level. The list on the Book Riot site includes links to past posts about books that fit the categories. They also have a PDF version you can download and/or print. Completing their challenge gets you a discount at the Book Riot store.

 

Cannonball Read 9 is more flexible. You read what you want. You decide your own limits and categories. The catch is that you have to write a review for the Cannonball Read site.  Each review has a link to the book on Amazon so if something catches your fancy, you can treat yourself to the book and know that the funds generated by Cannonball Read goes to cancer research. There's more information about the how and the why at the site. 

Cannonball Read is also run by the people behind Pajiba so the reviewers are funny, often sarcastic, and honest. There's always a huge range of genres represented, so even if you don't participate, watching that site is worth it for the reviews.
