Underdog Fantasy isn’t just a one-trick pony when it comes to bonuses, there’s a steady stream of offers for loyal users that keep things interesting well after you’ve claimed your signup reward. Let’s take a look at how some of the most popular ongoing features work:

• Refer-a-Friend Bonuses: Inviting your friends to join the action does more than just boost your bragging rights. Each time someone signs up using your unique referral link, you’ll pocket a $10 bonus to use on the site.
• Profit Boosts: Catching a little extra value is part of the fun. On select days like “More Money Mondays” or “30% Thursdays,” Underdog awards tokens you can apply to certain contests. These tokens can bump up your potential profits by a set percentage, making those winning tickets even sweeter.
• Deposit Bonuses: If your contest balance could use a refresh, keep an eye out for deposit perks like “Fill It Up Fridays.” Add funds to your account on these special days to earn a percentage-based bonus—think of it as a top-off for your playing power.
• Loss Protection and Pick Safeguards: Everyone has rough days, but Underdog softens the blow with features like “No Sweat Tokens,” which refund your stake if your entry doesn’t hit. There’s also “Vulture Protection” to guard against frustrating stat outcomes, and even “Rescues” that rebate your entry if an early injury derails your lineup.
• Sport-Specific Specials: For hoops fans, seasonal boosts like the “First Quarter Splash” can add an extra 20% to winnings tied to NBA first-quarter three-pointers.

Between these ongoing rewards and their core contest formats, Underdog Fantasy does a commendable job keeping regulars engaged and offering value well beyond the initial sign-up bonus.

Underdog Fantasy's strength lies in its unique and engaging contest formats that blend elements of traditional DFS with different timelines and tournament styles. The platform is a legal, online DFS site that offers fantasy contests for cash prizes, with a focus on making participation accessible and enjoyable for players of all experience levels. Whether you’re a stats junkie looking to analyze top NFL performers in crucial matchups or someone who enjoys picking standout athletes from a variety of sports each day, Underdog provides a wealth of stats and tools to help you make informed picks across their wide range of contests.

Pick'em

The most basic of the Underdog contests, in this game, you select 2 to 8 players from different teams and choose either “over” or “under” for one of their stat lines. The more selections you choose, the higher the potential payout. There are two types of Underdog Pick’em Contests: Standard or Flex. To win a Standard Pick’em Contest, all of your selections must be right. To win a Flex Pick’em Contest, only one of your selections must be right to guarantee a return. However, the potential maximum payout of the Flex Pick’em is less than that of the Standard Pick’em for the same selections. For example, if you get 5 out of 5 selections correct for a Standard Pick’em, your payout would be 20x your stake. For the same selections, if you went 5 for 5 on a Flex Pick’em, your winnings would only be 10x your stake.

Underdog recently expanded its Pick'em options with the launch of Pick8 in early June 2024, allowing you to add anywhere from 2 up to 8 picks per entry. This addition means you can chase a payout as high as 325x your money if you manage to sweep the board with eight correct picks. When making a Pick8 entry, your selections are automatically Double Flexed, so you can miss up to two picks and still get paid, a nice cushion for those high-risk, high-reward plays. And if you make 6 or more picks, you unlock access to “specials” within flexed entries, giving you even more ways to mix things up.

The simplest way to play Pick’em is the Higher/Lower format

In the Higher/Lower pick’em format, you’ll be presented with projected stat lines for various players (think Steph Curry projected for 4.5 three-pointers or Derrick Henry set at 86.5 rushing yards). Your job? Simply decide if the actual results will be higher or lower than the listed projection.

For example, if you believe LeBron James will score more than 20.5 points in an upcoming game, you’d select “Higher.” If you think he’ll fall short of that mark, you choose “Lower.” It’s an intuitive, user-friendly option that’s especially appealing to both seasoned fantasy players and newcomers looking for a quick and easy contest to join.

Rivals Format

Rivals offers a unique head-to-head twist where you select which of two players will outperform the other based on a predetermined spread. For instance, you might see a matchup like Jalen Hurts vs. Miles Sanders, with Hurts getting a 37.5 rushing yard advantage. If you choose Sanders, he’ll need to outpace Hurts by at least 38 rushing yards for your selection to be a winner.

In some cases, there’s no spread involved, turning it into a straightforward statistical battle—if both players finish with the same total after the contest, your entry is graded as a tie.

Champions

Champions is very similar to Pick'Em except now you are making picks and competing with other players for the prize. To join, you’ll draft a roster of 2 to 8 players, making “Higher” or “Lower” predictions on each player’s projected stat line. For every correct selection you make, you rack up Champions Points. The winner of a Champions tournament is the participant who collects the highest number of Champions Points by the end of the contest. While the structure is similar to Standard and Flex Pick’em—where getting all your picks correct brings a bigger reward and Flex provides some cushion—your ranking is determined solely by your accumulated points. So, if your picks consistently hit the mark, you’ll find yourself near the top of the leaderboard and in line for the Champion title.

Drafts

Battle Royale

Available for NFL only, this is a simple yet very fun game to play. In Battle Royale, entrants select a team through a snake draft against other players with no salary cap. The draft format is six rounds with six participants and each team will be comprised of one quarterback, one running back, one tight end, two wide receivers, and one Flex. The Battle Royale runs for one NFL week and you will be competing against all entrants from that week, not just your own draft pool. The goal is to have the highest score at the end of the week. Prizes are allocated in a top-down format that is determined before the contest begins and is displayed when you enter the contest.

Best Ball

Underdog Fantasy is a leading Best Ball Platform in the Daily Fantasy Industry. Best Ball is one of the most popular NFL Daily Fantasy contest types; however, Underdog also offers Best Ball Contests for NHL, NBA, MLB, and PGA. Best Ball is a season-long contest that does not require in-season management—your work is done once you complete the draft, meaning there is no trading, no dropping players, and no setting your lineup. Drafts are done in a snake draft style. Whoever scores the most points on your roster at the end of each week will automatically be placed into your team’s starting lineup for the following week. The goal is to accumulate the most points by the end of the season. Contest information such as prize pool, entry fees, and number of entrants vary by contest and are listed on each contest’s entry page.

Best Ball’s appeal lies in its simplicity and hands-off approach. Once your draft is complete, there’s no need to worry about waiver wires or lineup changes—Underdog’s system automatically starts your highest-scoring players each week. This makes it perfect for those who want the fun of drafting without the weekly grind of roster management. If you find yourself itching to draft in the quiet months between sports seasons, Best Ball offers a great outlet, letting you participate in as many drafts as you like, even if your friends aren’t quite ready for fantasy season.

A few key features of Best Ball contests include:

• Snake Drafts: The draft order reverses each round—if you pick last in the first round, you pick first in the next, and so on.
• Set Rosters: Your drafted team is locked in for the entire season. No add/drops or trades, so drafts can be “slow” with several hours allowed per pick.
• No Lineups to Set: Highest scorers are slotted in each week automatically.
• Locked Positions & Scoring: Roster and scoring settings are fixed, so there’s no tinkering with league formats. Just focus on drafting the best team possible.

Best Ball contests come in a variety of formats, with differences in group size, entry fees, and prize structures, but all share the same core gameplay. With the biggest prizes in fantasy and the convenience of “draft and done” play, Best Ball is a great fit whether you’re a casual fan or a seasoned fantasy veteran. If your schedule or budget allows, it’s definitely worth giving Best Ball a try.

Best Ball - Weekly Winners

New to Underdog Fantasy, Best Ball Weekly Winners is similar to standard Best Ball except that there are payouts at the end of each week rather than at the end of the season. In Weekly Winners, you won’t just be competing against your draft pool but against every other entrant in the Best Ball Weekly Contest. While you will draft your team only once, each week is a new competition and your team starts with a score of zero. At the end of each week, the entrants with the highest scores are awarded prizes. These prices are specified on that contest entry’s page. 

Best Ball - Playoff Weekly Winners

Another new Underdog Fantasy Best Ball format, in Playoff Weekly Winners, each week of the playoffs is a new competition and your team starts at zero points, competing against every other entrant in the Playoff Weekly Winners Contest. You will draft only one team and that will be your team for all four weeks of playoffs. At the end of each week, the entrants with the highest scores are awarded prizes. These prices are specified on that contest entry’s page. 

Underdog’s contest selection ensures there’s a format for every fantasy sports fan—whether you want the rapid-fire excitement of daily pick’em contests, the strategic depth of season-long best ball, or the thrill of competing in snake drafts for weekly cash prizes. With intuitive tools and comprehensive stats for athletes across all major sports, Underdog Fantasy makes it easy to dive in and start building your winning lineup.

Underdog Fantasy currently offers regular contests for the NFL, NBA, MLB, NHL, and PGA. Other sports are also offered intermittently such as Tennis, E-Sports, and more.

In addition to the mainstays, you’ll find a variety of other options popping up throughout the year, including college football (CFB) and college basketball (CBB)—especially during big events like March Madness and bowl season. Soccer, MMA, Boxing, and Esports also make appearances, though not always with the same frequency or depth as the traditional leagues.

Here’s a snapshot of the sports you can expect to see featured:

• NFL, NBA, MLB, NHL, PGA – Core offerings with regular contests, daily snake drafts, Best Ball, and notable tournaments like The Biggest Board or The Albatross.
