Where Is Underdog Available?

As someone who plays DFS daily, I can tell you firsthand that one of the most confusing parts of the game right now is figuring out exactly what you are allowed to play depending on where you are sitting. DFS regulations vary wildly across state lines—so even if you can download the app, you might not have access to every game mode.

Pro Tip before you dive in: If you live in a state where Pick'em isn't allowed but Drafts are (like New York or Ohio), don't sweat it! Using your ACTION promo code on Best Ball tournaments or daily snake drafts is still one of the highest-value ways to build a bankroll on the platform.

What Are Users Saying About Underdog? 

To get a fair spread of thoughts on the app, we asked beginner and expert fantasy players their thoughts. Newbie Joe Beguiristain had this to say: 

You may or may not have heard of Underdog, but seeing as you are reading this, you must know by now. Seriously, Underdog has become a major player in the DFS space, with strong brand awareness and a cool logo. (I like dogs.)

Getting to things that you actually care about, the Underdog app may not jump out immediately, but it functions very well. The home screen welcomes you with promotions, trending picks, popular picks, and the key matchup of the day. In other words, it’s what a home screen should be.

Of course, you can also search for particular players, teams, or stat types to make picks on. And if Pick’em isn’t your thing, you can head over to Drafts and get in on some old-school DFS action.

Stephen Pierce, a seasoned fantasy player, had this to say:

Making picks for NBA or NFL games on DFS apps has been something fun for me to research and do for years now. Sleeper and PrizePicks are the most popular ones for me and my friends, but we’d heard a lot about Underdog too. Underdog’s reputation is pretty good, so I decided to add it to my DFS rotation this year.

I was really impressed with the Underdog app and DFS experience. Underdog has tons of great stats for all kinds of athletes to make picks on. I tend to focus on big NFL performers in important matchups, but Underdog makes it easy too to also focus on those good performers in all kinds of sports each day. 

Underdog also gave me an onslaught of options for daily drafts to enjoy as well. Me and my friends will do daily drafts in basketball or football games, and we’ve added Underdog to our favorite apps because of how much fun we’ve been having. We can create our own drafts with each other or join big pools too. Underdog has been a great DFS option for all of us who play on these each day!

Who Is Underdog For?

People ask me if Underdog is worth their time. My answer depends entirely on your daily routine. Do you enjoy agonizing over strict salary caps for six hours? Then look elsewhere. But if you want fast action, this app delivers.

It caters perfectly to fans who want to draft a Best Ball team in ten minutes. It works beautifully for stat junkies who prefer picking player projection totals over building massive rosters.

• The Fast-Paced Drafter: Underdog's snake drafts are legendary. You jump in a lobby, pick your guys, and you're done. No salary caps, no agonizing over pricing.
• The Stats Junkie: If you spend your time researching how many shots on goal a hockey player gets, the Pick'em lobby is your playground. Just choose "Higher" or "Lower" on the projections.
• The Busy Fan: Best Ball is the ultimate set-it-and-forget-it mode. You draft your team once, and the platform automatically starts your highest scorers every single week. No waivers, no trade drama. Just pure drafting.

Why Underdog's 'Flex Play' Feature is Perfect for May

When building your Pick'em slips during the intense May sports calendar, utilizing the Flex Play option is a bankroll lifesaver. Here is exactly why you should consider it:

• Margin of Error: Unlike standard slips where one bad beat ruins your night, Flex Play allows you to miss one pick and still walk away with a payout.
• League Volatility: NBA and NHL games feature unpredictable blowouts and sudden foul trouble. That unpredictability easily tanks a perfect entry. Flexing your slip adds a needed layer of insurance.
• MLB Pitching Chaos: Baseball managers pull starters earlier than ever. If your targeted pitcher gets hooked in the fourth inning, a Flex Play ensures your entire slip doesn't go down with him.
• Strategic Stacking: You can aggressively target correlated outcomes—like a quarterback and his primary receiver—while maintaining a safety net if the game script flips unexpectedly.

I consistently use Flex Play on my four-pick and five-pick entries. While the maximum multiplier drops slightly, the consistent returns keep my account balance moving in the right direction.

Underdog Pick'em Strategy: Standard vs. Flex Play

Let's talk strategy! When you're putting together your Pick'em tickets on Underdog, knowing exactly when to choose "Standard" versus "Flex" is a total game-changer for your bankroll.

Here is how I like to break it down:

• Standard Play (Going All-In): This option means you need a flawless ticket. If you pick three players, all three have to clear their projections for you to see a dime. The upside? The payouts are massive. I usually save this for smaller, deeply connected picks—like pairing a point guard's assists with his favorite center's points.

• Flex Play (Building in a Safety Net): Think of this as your built-in insurance policy. If you put together a five-pick slip and one of your players just has an off night, you still get paid! The overall return is a bit smaller, but the peace of mind is totally worth it.

Flex is my absolute go-to for the Conference Finals right now. Playoff minutes can get weird, and if a game turns into a blowout, your star player might get benched in the fourth quarter and miss his numbers. It's also a total lifesaver for baseball. Hitting a baseball is wildly unpredictable, so having that safety net means one bad night at the plate won't instantly trash your ticket.

The Bottom Line: Stick to Standard when you have a super confident two- or three-leg combo, but definitely switch to Flex when you're building bigger tickets or mixing in different sports where crazy things happen!

Betting Options & Sports Market Coverage on Underdog

While Underdog is not a sportsbook like FanDuel or DraftKings, they do have some entertaining and rewarding daily fantasy games for users to try out.  

Underdog Best Ball Tournaments

Users draft players for their roster in a snake draft to compete against other users for prizes at the end of each paid entry period. The players that users draft will gain points based on their performances in their respective sport. The prizes are determined on how much is pooled in each contest by the users.

Pick'Em Contests

Pick 'Em is a game type that's as easy as it sounds: users pick the over/under on certain players' stats for that days games. They must choose from a minimum of two different teams to submit their bet. Players can have fun choosing, for example, NBA players' PTS + RBS + ASTS for the matchup that night that they are looking at.

Daily Drafts

Users can join daily drafts by clicking on the 'drafts' section of the website. Players compete in the sport they choose. Examples would be NHL matchups that night, NFL playoffs, et cetera. The entry and prize amount in Underdog contests varies, but they are usually low stakes. 

Battle Royale

Underdog’s Battle Royale format differs from a standard fantasy contest in a few unique ways. Upon entering, you will get to pick players in a snake draft against six to twelver other users. However, you aren’t just competing against that group; you are competing against every user in every group for a specific time period.

Underdog Customer Service

Underdog has a couple of different ways to contact customer support at the company.

• 📞 Call — +1 917-267-2182
• 📧 Email — support@underdogfantasy.com

Responsible Gaming & Spending Controls at Underdog

Playing daily fantasy sports should always be about having fun and sweating the games. Underdog gets that, and they’ve built in some helpful tools right inside the app to make sure you play responsibly and stay within your comfort zone.

• Deposit & Entry Limits: Set your own caps on how much cash you can deposit or play daily, weekly, or monthly. It’s an easy way to make sure you stick to your budget.

• Time-Outs: Sometimes we all need a quick breather. You can hit pause on your account for a set amount of time until you're ready to come back.

• Self-Exclusion: If you decide you need to step away from the app entirely, you can use the self-exclusion list. This locks your account and completely stops all of those promo emails and notifications.

• State-Mandated Deposit Limits: Keep in mind that certain states enforce their own maximum deposit limits. Currently, Massachusetts is capped at $1,000 per 31 days, Maryland at $5,000 per 31 days, and Tennessee at $2,500 per 31 days.

• Account Safety: Underdog encourages users to routinely reset their passwords and actively monitor their transaction and payment histories. You can also manually lock your account if you suspect someone else has gained access.

• Parental Controls: Underdog strictly verifies that all users are of legal age. However, if a minor improperly uses a parent's financial information to create an account, parents are urged to contact support@underdogfantasy.com immediately for account closure and appropriate security measures.

And remember, if you or a friend ever need some help managing your play, Underdog makes it easy to find support by linking directly to resources and hotlines like 1-800-GAMBLER right in the app.
