Underdog Fantasy Best Ball Mania 2024: What Is It, How To Play & More

Do you love the NFL season and fantasy football, but don’t quite have the time to fiddle with your lineup week in and week out? Or maybe you have enough leagues on your plate already where you’d like one where you can draft and not have to stress about it again?
Well, then Underdog Best Ball Mania is for you! It’s become one of the most popular ways to enjoy the NFL season, not to mention a lucrative one.
In this article, we’ll provide you with the ins and outs of Underdog Fantasy Best Ball Mania, the massive $15 million prize pool and more!

What Is Underdog Best Ball Mania?
It’s only fitting to start with the basics. In that regard, Underdog Best Ball Mania can be thought of as an extended, collaborative normal best ball contest. Whether you’re new to the scene or just need a refresher, let’s quickly discuss best ball contests overall.
You’ll be drafting a year-long fantasy football team just as you normally would once you sign up here; however, there isn’t any roster management that takes place after that. It’s called NFL best ball due to your best players being used each week automatically.
These best ball contests consist of singular leagues, and that’s where Underdog Fantasy Best Ball Mania comes in. Underdog Best Ball Mania consists of a massive collection of leagues that will then be condensed throughout multiple rounds. So, think of Underdog Best Ball Mania as a normal best ball contest combined with thousands of other best ball contests worth $15 million in total!
2024 Underdog Best Ball Mania Details
Now that you have the general overview, the details of Underdog Best Ball Mania are of utmost importance. First and foremost, it’s vital to know what the roster construction will be prior to drafting your team, which we’ve shared below:
- 1-QB, 2-RB, 3-WR, 1-TE, 1-Flex, 10-Bench
Now, let’s dive into where Underdog Fantasy Best Ball Mania separates itself from normal best ball contests. The entry fee is just $25, and contestants can enter up to 150 times! There will be four total rounds, so for simplicity's sake, let’s break down how each one works individually.

In total, Underdog Best Ball Mania will consist of 672,672 total entries. During round one, which occurs during Weeks 1-14 of the 2024-25 NFL regular season, there will be 12-person groups. After those first 14 weeks, the top two contestants in each group will advance to the second round.
Round two then takes place during Week 15, but now, the groups will consist of 13 contestants. From here, only the winner from each group will advance to the third round. From here, the process repeats.
That is to say that round three is Week 16 of the 2024-25 NFL regular season with the top contestant from each group advancing to the final round. The only difference here is that round three consists of 16-person groups.
Round four is the final round of Underdog Best Ball Mania, and rather than individual groups of different sizes, there is one, huge 539-person group with all those remaining in the contest. The top, grand prize of a whopping $1.5 million goes to the overall winner, but the entire final group will receive something!
