How does Underdog DFS work?
Like most DFS platforms, Underdog offers several ways to play. The three major game modes available at Underdog are called Drafts, Champions, and Pick’em. That said, in California, the Pick’em games are not available, only Champions and Drafts. Let’s talk a little about each and how they work.
Underdog Drafts
The two most popular types of Underdog Fantasy Draft games are:
- Best Ball
- Battle Royale
Best Ball is a uniquely straightforward format for season-long fantasy drafts. Every Best Ball contest is a snake draft league, with no trades, substitutions, waivers, or any of the other bells and whistles that normally keep fantasy players busy.
All you need to do is find a Best Ball contest with an entry fee and prize pool you like, join it, draft your team, and you’re all set. Scoring is cumulative (i.e., no head-to-head matchups), and your lineup is automatically optimized for you each week. This makes it the easiest fantasy league format on the market, perfect for casual players or anyone who doesn’t want to spend time keeping up on injury news every week.
Meanwhile, Battle Royale contests follow the same basic format as Best Ball contests, except that Battle Royale contests are daily or weekly, rather than season-long. For instance, you could join a Battle Royale league exclusively for one day’s worth of NBA games. Battle Royale entry fees vary from $3 to $300. The contests feature 3 to 13 players who can experience all the excitement of fantasy sports without committing to a league for a full season.
There are other ways to play Underdog Draft contests, including head-to-head and tournaments.
Underdog Champions
Champions is Underdog Fantasy’s season-long format that focuses on hitting performance goals rather than competing head-to-head against other users. After drafting a team, your roster is automatically optimized each week, with no trades or lineup decisions required. Instead of finishing in a specific place on a leaderboard, you earn rewards by reaching preset scoring thresholds over the course of the season, making Champions feel more structured and predictable than traditional fantasy tournaments.
This is where Champions differs from Best Ball. While Best Ball runs for the entire season and requires only a single draft, it pits your team against a defined group of entries, with payouts based on final standings. Champions removes that competitive ranking element and replaces it with milestone-based payouts, allowing multiple users to earn the same rewards. In short, Best Ball is tournament-style fantasy with higher variance, while Champions is a goal-oriented alternative designed for players who prefer steadier outcomes over leaderboard pressure.
Sign up at Underdog CA
Signing up for an Underdog account is easy. Visit the Underdog site, then fill in the requested information and click “Create account.”
You’ll be required to enter some basic information, including your email and date of birth, and you’ll also be asked to create a username and password. The Underdog promo code BETODDS should automatically appear in the “promo code” box, but if it doesn’t, enter it to be eligible for the welcome offer.
Note that you can also download the Underdog app from the App Store or Google Play and create your account that way. Again, be sure to enter the promo code! Be aware that the app is listed as Underdog Sports.
Is Underdog legal?
Yes, Underdog is completely legal to sign up and play in most US states. Keep in mind that, since Underdog is a daily fantasy sports platform, it is not subject to the same regulations and laws as CA online sportsbooks (if California had them). This means that it is legal in some states where sports betting isn’t, such as California
As mentioned above, keep in mind that while the overall platform is legal and available in CA, the pick ’em-style games are not. Essentially, what you can play in CA are the more traditional kinds of fantasy sports games where you draft line-ups, not the pick’em games that can often resemble prop betting.
Can you win money at Underdog Fantasy?
Yes, you can win money when you play with Underdog. Underdog is a pay-to-play DFS platform, which means you pay entry fees or put down a stake when you enter contests. Naturally, since Underdog charges real money entry fees, the prize pools are also real money. There is no free-to-play option at Underdog.
The only time you will receive money on the site that cannot be withdrawn as real money is when you are issued a bonus. For example, any entries you receive from the first deposit match are paid to you in Underdog bonus credit. You can use these bonus entries to place wagers that return real money in profit, but you cannot withdraw the bonus entries themselves.
What’s great about Underdog?
Underdog is a clear standout among the DFS platforms on the market today. Here are some of the top reasons why.
- Underdog’s signature league formats like Best Ball and Battle Royale make taking part in a fantasy league easier than ever.
- You can take part in massive contests with insane prizes, like the Best Ball Mania events, which can have total prize pools in excess of $10 million.
- The Underdog iOS and Android apps have received excellent customer feedback, including a 4.8 out of 5 stars rating on the App Store
What’s missing from Underdog?
No DFS platform is perfect. From what we’ve seen so far, here are a few things that Underdog could stand to improve.
- While you can deposit using many methods, you have to use either PayPal or ACH/e-check to withdraw.
- It can take new players some time to get the hang of the unique Underdog game modes, and the app doesn’t offer much of a tutorial.
- Some users have suggested that the conditions on bonuses (e.g., playthrough requirements for bonus entries) could be made clearer.
Deposit & withdrawal options at Underdog
Depositing funds at Underdog is straightforward. You can add funds to your account with a credit card, debit card, PayPal, Venmo, Apple Pay, or online banking (Trustly). All deposits should be processed immediately. There is a minimum deposit of $10 each time you add money to your account.
When withdrawing, you can use either PayPal or ACH (eCheck), or request a check by mail. Please note that even if you deposit using a credit card or debit card, you will not be able to withdraw using that method.
Payout speeds can depend on the withdrawal method you choose. PayPal withdrawals will be processed slightly faster, with estimated payout times of 1-2 banking days, whereas an eCheck will take 2-4 banking days to reach your account. Check-by-mail cashouts can take 7-10 business days.
Can I play at Underdog California for free?
While you might find some DFS platforms, like Fliff Superstars, offer a free-to-play option, Underdog does not. While entry fees to Battle Royale leagues are often as low as $3, there are no leagues available that are free to enter. As a result, however, you are always eligible to win real money when you play with Underdog.
Underdog FAQs
Yes. Enter the Underdog promo code BETODDS and when you make your account, you’ll be eligible to take advantage of the welcome offer. Check out the Underdog Promo Code section and table above for full terms and conditions.
Users must be at least 18 years old in most states, including California. The minimum age is higher in a few other states. Be sure to check the terms and conditions if you are outside of CA and want to play at Underdog.
Yes, Underdog contests charge real money entry fees and pay out all winnings in real money as well.
Underdog is a fantasy platform, not an online sportsbook. You cannot find entries on moneylines, over/unders, or props. For CA players, Underdog offers a variety of fantasy contests, including Drafts like Best Ball and Battle Royale, as well as Champions contests. In these, you pay an entry fee, draft a team, and earn a payout if your team performs best.
Yes, Underdog is a safe and legal platform that accepts customers from most US states. Payments are processed securely, and all customer data is safely stored. You can legally and safely play with Underdog as long as your state permits daily fantasy sports (DFS) platforms.
Underdog is not directly comparable to online sportsbook apps like FanDuel and DraftKings Pick6. While FanDuel and DraftKings both began as DFS platforms, both have shifted their focus to sports betting in a massive way.
If you are looking for a dedicated fantasy platform, consider choosing Underdog. Also, keep in mind that if you are located in states where daily fantasy platforms are legal but online sportsbooks are not (e.g., California), you will be able to play with Underdog, but you won’t be able to sign up with an online sportsbook.
