Underdog Promos for Existing Users
From what I’ve seen at Underdog, some of the most useful promotions for college football and the NFL are the ones that protect your entry from the unpredictability of the game.
Vulture Protection is a perfect example; it keeps my pick safe from an unexpected rushing touchdown by a non-running back. Similarly, the Pick’em Rescues or “Safety Net” promo is crucial. It protects my entry fee if a player gets injured early, which is a common and frustrating risk in football. These promotions give me peace of mind, knowing that a random event won’t immediately tank my entry.
The other type of promo I find most valuable is anything that lets me boost my winnings. Player Multiplier Boosts and Supercharge tokens are a game-changer. They allow me to increase the payout on a specific player I have a strong feeling about or a particular entry with a favorable matchup.
I get to use my football knowledge to make a strategic decision that could lead to a much bigger win. These promos don’t just protect my money; they give me a way to maximize my profit and add an extra layer of strategy to the game.
What I’ve Learned From Using Underdog Every Day
As a sports fan in Florida with limited legal betting options, Underdog has been a way to add extra engagement to games without traditional sports betting. It’s similar to fantasy sports in that it makes regular seasons and tournaments feel more meaningful.
I’ve used the app for over a year across pick’em contests, best ball tournaments, large DFS slates, and head-to-head drafts in NBA, MLB, NFL, golf, and hockey. The experience is consistent across formats and easy to use on a daily basis.
What I’ve learned about Underdog
The Underdog app is excellent. If you’ve only used it, you might not realize how good it is compared to other DFS apps. It’s clean, fast, and easy to navigate, and deposits and withdrawals are simple. Overall, the user experience stands out.
Underdog also makes watching sports more fun. Whether it’s needing rebounds from Giannis Antetokounmpo in a late NBA game or birdies from Justin Thomas on a Sunday, every play feels more meaningful when you have action on it. It adds real stakes to the viewing experience.
Winning is the hard part. Results can be inconsistent, and it’s easy to lose more than you win. But with small entry fees, it still works well as entertainment value.
Best ball contests are a standout feature. They add a longer-term layer to DFS, especially in events like golf majors. Following players like Justin Rose or Corey Conners across a full tournament makes events like The Masters even more engaging.
What do I think Underdog could do better?
While Underdog is really about as good as it gets with respect to daily fantasy contest experience and entertainment, there are a few things that I think could make Underdog even better.
- Underdog should entice new users with a free entry into a major contest. After making a deposit of say $10 or so, Underdog should also give a free entry into a best ball contest for example. This will encourage long-term engagement of its users, and also be a nice additional welcome offer component.
- No rewards or loyalty program. I think there is tremendous potential here that would really solidify Underdog as a long-term dominant player in this space. The more you play, users should be earning rewards points. The more points, the higher “tiers” of status you should achieve. The highest tiers could offer some very interesting rewards such as exclusive contests or fantasy entries into the best and biggest contests on the platform.
Underdog is still a relatively new product, so I expect that Underdog might roll out some of these features or improvements in the future.
Is Underdog Fantasy Legit?
Since Underdog is less established than DraftKings, FanDuel, or BetMGM, it is fair to ask if it is legit.
Underdog was founded in 2020 and has raised significant funding from well known investors, including Mark Cuban and Kevin Durant, along with major firms like BlackRock.
From our experience, everything works as expected. Deposits and withdrawals are smooth, and contests run without issues.
It is not perfect, and there is still room to grow, but nothing that raises concern.
So yes, Underdog is legit.
Why we love Underdog here at SDS
Unfortunately for us SEC football fans, most of the southeastern states have not legalized sports betting. Louisiana and Tennessee are are the only SEC football states with legal online sports betting. Are more coming? Probably, but for now, it is what it is.
But, we can have a ton of fun and scratch that competitive itch by playing Underdog and making picks around college football games. Underdog is available and legal in all SEC football states except Louisiana. Yep, that means all of those big states such as Georgia, Florida, Alabama, South Carolina, Mississippi, etc. can all have a ton of fun playing for real money on college football picks on Underdog. Tennessee folks, well, you’re just lucky as you have the ability to do legal sports betting and daily fantasy, both.
What does it look like to play Underdog in relation to college football games? I’m glad you asked! Let’s get into it.
Underdog Fantasy App: Contest Types
These are the types of contests you’ll find on Underdog:
Best Ball Contests
The Underdog best ball contests garner a ton of attention. Not only do the huge NFL Mania $15 million prize pool contests bring in a lot of press for Underdog and their fantasy platform, but these best ball contests lead to a wide range of content around guaranteed prize pool and best ball strategy. Once you get into these contests, it’s hard to get out. They are incredibly fun.
And hey, Best Ball Mania has a $25 entry fee. So those $50 in bonus fantasy entries? That could net you 3 Best Ball Mania lineups!
Best ball tournaments aren’t necessarily something that haven’t been around, but Underdog has indeed taken these huge contests to another level both with the user interface and app quality, but of course, the huge prize pools that get a lot of attention.
The season long, big prize pool contests are incredibly fun. Here’s how it works:
- Draft your roster before the season starts. This might mean the NFL season, the MLB season, the PGA majors season, whatever.
- The contest is divided into elimination rounds. In the NFL, it’s often the first 14 weeks of the regular season. In the PGA, it’s the first major. Because these contests offer huge prize pool money that is concentrated to the top winners, you have to make it through a few rounds and try to get into the final round.
- The best ball mechanism means that you don’t have to set your roster or worry about trades or waiver wire pick ups. The best scoring people on your team count each week, or each game. It’s simple.
- You can begin layering in some advanced strategy by deploying multiple entries in a single contest. Some of the large contests allow you to enter as many as 150 entries.
The $50 in fantasy entries offer with Underdog promo code SDS really gives users a great opportunity to build up some entries in these best ball contests. For example, the NFL Best Ball Mania contest has a $25 entry fee. If I leverage the SDS Underdog Promo Code and do the full value of the entries, I can score $50 in fantasy entries for my bankroll.
Battle Royale Daily Fantasy Draft
Underdog offers standard daily fantasy contests where you draft a lineup and compete against other users over a single slate of games.
Battle Royale is where things get more interesting. Instead of a typical lineup build, you enter a live snake draft with a small group, usually 6 to 12 users. But you are not just competing against your draft room. You are competing against every entry in the contest.
For example, in a six person draft for an NBA slate, you pick six players in snake format. Even though you only draft against five other users, your lineup is scored against thousands of entries. That means smaller draft rooms, but much larger prize pools.
The payouts reflect that structure. It is difficult to hit a top prize, but a large portion of the field still cashes, making it easier to win something while still chasing a bigger score.
Here are some screengrabs from my first NBA contest on Underdog:
Tips for your first Battle Royale draft:
- Make sure you understand the point scoring. On this NBA draft, I didn’t realize until a few picks in that steals counted for more points than I realized.
- The draft goes quick! When it starts, it moves quick and you might struggle to keep up. Get a feel for who you want before it begins.
- Go with a very small entry fee for your first draft, so you don’t risk much money on your first go-around. Use it as a learning experience.
Regular Daily Fantasy Drafts
While Battle Royale is a large field contest, Underdog also offers simple head to head drafts against one opponent.
You each draft six NBA players, and if you win, you nearly double your entry after rake. The drafts take just a couple minutes, making it an easy way to get action on a nightly slate.
The downside is repetition. With a small player pool, you end up drafting the same top players most of the time, so results can feel a bit random.
Still, it is a fun and simple format, with enough strategy to keep things interesting.
Important Note:
As I was getting used to the Underdog platform, I entered a daily fantasy two player NBA matchup. I sat there for a minute and nobody entered the contest. So I left, and joined another. Nobody entered for a minute, and so I left again, and shut the app off. A few minutes later, I got a notification from Underdog that my draft was about to start! I didn’t realize that once you enter, you’re in, even if you leave. So I completed the draft. Then I got another notification saying my draft was about to start! If you remember, I entered two drafts casually and left both. Well, I was locked into both. So without realizing it, I had committed to two NBA drafts for the same day. Be aware that if you enter the contest, you’re in.
Underdog Pick’em Contests
As someone who kind of exited the daily fantasy space a few years ago after the big wave, it’s the pick’em contests that pulled me back in to Underdog. These contests are quite similar to prop bets, and more closely resemble actual sports betting than anything else in fantasy.
There are two types of pick’em contests on Underdog. Higher/lower pick’ems (which resemble over/under player prop bets in sports betting) and Rivals. Regardless of the type, you have to combine at least 2 picks and as many as 5. The more you combine, the higher the multiplier or potential payout.
Higher/Lower
On higher/lower pick’ems, you are making a pick on an individual player and whether they will go over or under a specific stat total. For example, you might pick that LeBron James will score over or under 28.5 points against the Clippers in a game.
Scroll down to see more screenshots around higher/lower picks across a variety of sports on the Underdog platform.
Rivals
In Rivals picks, you make a pick between two players around a specific stat category with a “spread” applied to one of them to even out the odds a bit. In the screenshot to the right, you can see you are picking between Jalen Hurts +37.5 rushing yards vs. his teammate Miles Sanders. If you pick Hurts, you think he’s going to rush for at least 37.5 more yards than Sanders.
Multipliers
How much can you win? Here are how the multipliers work on the Underdog Pick’em contests:
- Two picks: 3x
- Three picks: 6x
- Four picks: 10x
- Five picks: 20x
Curious what this looks like? Here are some screenshots on picking higher/lowers on Underdog across NFL, NBA, MLB and even college football.
The interface is really nice. Although, I’d like to see headshots on the college football pick’ems soon! New users can navigate this pretty easily. You make your pick, you see the multiplier indicator at the bottom light up which indicates how many picks you’ve made and how much money you can win. Pretty simple stuff.
Playing College Football on Underdog
One of the reasons we love Underdog and are passionate about our own Underdog promo code for our users is because this type of action is live and legal in many of the college football states where sports betting is not legal.
