Underdog Fantasy review
Since its debut in 2020, Underdog Fantasy has been steadily gaining traction in the competitive fantasy sports industry. The company has differentiated itself from the industry giants by offering a variety of games.
Traditionally, daily fantasy sports have used a salary cap model in which users build the best possible lineup while sticking to the game’s budget. Underdog has taken things in a different direction with games like best ball and battle royale.
In addition, you’ll find more than just daily games at Underdog. Some contests span an entire week, and even season-long offerings via its best ball contests. Let’s take a closer look at Underdog Fantasy.
User interface
The team behind the scenes at Underdog Fantasy has a wealth of experience. That becomes apparent at first glance at the user interface. Once you’ve set up your account, you’ll find a clearly laid-out lobby.
Navigation is simple, with dedicated prompts for each available sport and game type. In the account section, you’ll find links to game rules, customer support options, payment information, and more. Another feature is the built-in news feed.
There are feeds available for the top sports. You can scroll through and view the latest headlines with ease and expand an item to read more when something catches your eye. Overall, the interface at Underdog Fantasy is user-friendly.
Customer service
Underdog Fantasy offers customer support via email or by submitting a request directly through the website or app. Once logged in, you click to access the account section and locate the “contact support” tab.
During our test run, we had trouble logging in to the website after accessing the mobile platform without issue. We sent an email to customer support and received an instant reply that the request was received.
A representative followed up and addressed the issue, which was a simple fix that was cleared up quickly. While we can’t promise that support will always be delivered this promptly, Underdog gets a thumbs-up on the support front in this case.
Deposits and withdrawals
Underdog Fantasy sticks to the basics with payment options. You can find the cashier section by clicking on the dollar sign icon. That’ll take you to the deposit screen, where you can choose between PayPal and a credit/debit card.
For withdrawals, you can select PayPal or Interchecks. If you choose the latter, you’ll receive an email notification with instructions on how to enroll and receive an e-check. Deposits process instantly, while withdrawals tend to receive approval quickly on Underdog’s end.
The speed at which you receive your funds will depend on the method you choose. Compared to other leading fantasy sports sites, Underdog has fewer payment options, but covers the bases with a couple of easy-to-access methods.
Game selection
At Underdog Fantasy, you’ll find a menu of games that have proven popular with users since its inception:
- Best ball: Participate in snake drafts with other users to compete for prizes. Choose your players when it’s your turn, and then “set it and forget it,” as the platform will choose your optimal scoring lineup. Field sizes, buy-in amounts, and game lengths vary, and larger tournaments are also available.
- Pick’em: There are two formats to choose from. For rivals, you choose which of two players you think will score more fantasy points. Higher/lower gives you a range of player benchmarks to choose from, similar to wagering on player props. You can make two to five picks for both types of contests.
The Underdog Fantasy lobby has two distinct tabs for draft and pick’em games, so you can easily find what you’re looking for. We’ll take a closer look at the types of games later in this guide, including the rules, scoring, and available options for both formats.

Underdog Fantasy user reviews
When deciding on where you want to play fantasy sports, personal preference will be a large factor. However, reviewing others’ consensus opinions can help you narrow down the field. Here are some of the current opinions on what Underdog Fantasy brings to the table.
Underdog Fantasy iOS reviews
The Underdog Fantasy iOS app ranks in the top 30 in the sports category in the App Store. The majority of the reviews have been positive, with many users specifically calling out customer support and overall enjoyment.
A minority of reviewers rated the app at three stars or fewer. Gripes among that group included the app’s usability and dissatisfaction with the game selection. Overall, the Underdog iOS ranking compares well to competitors.
- Overall consensus: 4.7/5 stars with more than 11,000 ratings
Underdog Fantasy Google Play Store reviews
Underdog Fantasy has been downloaded from the Google Play Store more than 100,000 times. The reviews have been mostly positive, leading to a solid overall score. However, there are some complaints from several users.
Among those who ranked the app highly, common comments focused on satisfaction with the game selection. On the negative side, several users noted frustration with the app experience compared to the website.
- Overall consensus: 4.4/5 stars with more than 3,500 ratings
Underdog best ball guide
Best ball has been around for some time, but interest in the game has grown in recent years. Underdog Fantasy has been one of the catalysts that has helped make that happen. Best ball is a featured offering at Underdog, with several options.
From the main lobby, the “Draft” tab lists all of the current offerings and available sports. There are tournaments and smaller contests to choose from, each with varying numbers of entrants, entry costs, and drafting timeframes.
- Daily: The draft and the game itself draw from a single slate of games for a specific sport.
- Weekly: Pick your team for a full week of play. You’ll accumulate points when your players are in action.
- Season-long: Draft a roster for an entire season. Set it, forget it, and earn points from your optimal lineup.
- Battle royale: You draft in fields of six players and compete against other users in a tournament for prizes.
Best ball drafts are basically the same as a standard season-long fantasy sports draft, as participants take turns making their selections using a snake format. The big difference is that traditional season-long fantasy requires roster management.
For best ball, you make your picks, and that’s it. The platform will automatically select your optimal scoring lineup. In the account section of Underdog Fantasy, you can find a complete explanation of rules and scoring by sport.
Using the NFL as an example, you’ll draft 18 players. There are no kickers or defense. Your optimal scoring lineup will be for the eight best-performing players at their respective positions: QB, RB, WR, and TE.
Speaking of the NFL, one of Underdog’s signature events that has helped put it on the map is “Best Ball Mania.” This tournament costs $25 to enter and aims to attract over 600,000 entrants competing for $15 million in prizes.
If tournaments aren’t your thing, smaller best ball games run from two to 12 entrants, with entry fees typically ranging from $3 to $100. For players who like best ball, as well as those who have never played but want to get involved, Underdog is a good choice.
Underdog pick’em guide
Unlike traditional online sportsbooks or even social sports betting sites, Underdog Fantasy’s pick’em games exist somewhere between fantasy sports and player props. Instead of drafting players, you’re making your selections from the available choices. There are two ways to play pick’em at Underdog Fantasy.
- Higher/lower: Similar to an over/under sports bet, you’re making your picks against the available benchmark line. If you expect the player to exceed the line, choose a higher value; otherwise, choose a lower value. To play, you’ll make two to five picks from the available options.
- Rivals: Instead of wagering on exact player outcomes, you choose which of two players you think will perform the best when it comes to a specific metric. Once again, you make between two and five selections per entry. The payout potential rises based on the number of selections you make.
You’re also in control of your entry fee for the pick’em games. You can play with as little as $1 all the way up to a maximum of $500 per entry. Payouts vary with the number of selections, but can reach up to 20x with five correct picks.
As always, it’s challenging to be right with all of your picks to win. Underdog Fantasy does provide some assistance on that front. If you use the “Insured” option, you can still win with one missed selection when you make three or more picks, albeit at a reduced price.
Underdog DFS guide
When most users think of daily fantasy sports, thoughts turn to the challenging salary cap contests that are available at the industry stalwarts.
There’s no salary cap here. Underdog Fantasy takes a different approach to daily fantasy sports.
There are drafts available for single days and tournaments where you can compete for big prizes. Some tournaments allow multiple entries, but Underdog tries to address the massive multi-entry problem that plagues other sites with many single-entry contests.
Comparing Underdog Fantasy with other platforms
So how does Underdog Fantasy stack up with the competition? Here’s a side-by-side look at how it compares with two of the DFS heavyweights in some key areas:
| Feature | Underdog Fantasy | DraftKings | FanDuel |
|---|---|---|---|
| Game Types | Best ball, pick’em | DFS salary casp, best ball | DFS salary cap, best ball |
| Availability | Best ball: 41 states Pick’em: 30 states | 44 of 50 states | 44 of 50 states |
| Banking Options | PayPal, credit or debit card, Interchecks | PayPal, Venmo, credit or debit card, online banking, prepaid card | PayPal, Venmo, credit or debit card, online banking, prepaid card |
