Kansas City and Denver meet in an important AFC West showdown, with both teams looking to make a statement. Iโ€™m looking at Patrick Mahomes Higher than 224.5 passing yards and Bo Nix Higher than 201.5 passing yards as two options to consider for Sunday afternoon.

With its user-friendly Pickโ€™em format and exciting player prop contests across multiple sports, Underdog has quickly become a go-to platform for DFS fans everywhere.


Underdog Deposit 50% Match Up to $1,000 + Keep Your Million

Keep Your Million starts eligible users with a virtual $1 million balance, known as Milly Bucks. Youโ€™ll answer up to 20 Higher or Lower questions, choosing how much of your virtual balance to place on each side of the projection.

The objective is to make it through all 20 questions while preserving as much of your balance as possible. If you complete the game, you can be awarded the remaining amount as Underdog bonus funds, up to $1 million.

Keep Your Million is only available to eligible new users who select the promotion as their welcome offer. Offer availability and requirements can vary, so review the current Underdog terms before signing up.

How to Redeem the Underdog Promo Code

  1. Select โ€œCLAIM BONUSโ€ to access the Underdog offer available in your location.
  2. Click โ€œSIGN UPโ€ and create your Underdog account.
  3. Apply the promo code SBD during sign-up, if prompted. Your code may be automatically applied through the promotional link.
  4. Make a first deposit of at least $10 to qualify for the applicable deposit match.
  5. Follow the promotion’s terms, eligibility requirements, and deadlines to unlock and complete Keep Your Million.

How Does Keep Your Million Work?

Keep Your Million gives eligible users a virtual $1 million pot of Milly Bucks. The game includes up to 20 player-projection questions, and each question requires you to choose Higher or Lower.

Step 1: Choose a question

Select a player projection and decide whether you think the playerโ€™s result will finish Higher or Lower than the listed number.

Step 2: Divide your balance

Use the slider to decide how much of your virtual balance to place on Higher and how much on Lower. You can put your entire balance on one side or split it between both.

Step 3: Submit your pick

Once you submit your selection before the applicable game begins, it is locked and cannot be changed.

Step 4: Carry your balance forward

After the question settles, the amount placed on the correct side becomes your remaining balance for the next question.

Step 5: Continue through 20 questions

Continue making Higher or Lower selections for up to 20 questions. If you successfully complete all 20, the remaining balance can be awarded as Underdog bonus funds, subject to the promotionโ€™s terms.

If your balance reaches $0 before you complete the game, you will not receive a payout. Milly Bucks are promotional funds and cannot be withdrawn or used outside of Keep Your Million.

Keep Your Million Terms and Conditions

Keep Your Million is limited to eligible users who select the promotion as their applicable welcome offer. A minimum $10 deposit may be required, along with other eligibility and timing requirements.

You cannot withdraw promotional site credit and entry tokens directly as cash. Any winnings generated through eligible play are subject to Underdogโ€™s applicable terms. Bonus entries do not expire, while bonus funds and site credits may expire.

Promotion availability, eligibility requirements, deadlines, and other terms are subject to change. Review Underdogโ€™s current terms and conditions before participating.

What is Underdog Keep Your Million?

Keep Your Million is a promotional game that can be accessed by eligible new Underdog users. You are given a virtual amount of $1 million and then have to go through 20 questions as a player, deciding whether to choose Higher or Lower and also choosing how much of your balance to risk on each choice.

To unlock the promotion you must make a minimum deposit of $10; you will have 7 days to unlock Keep Your Million and then up to 60 days to complete the game.

The concept is simple: answer all 20 questions without losing your whole balance. If you have any balance left at the end, you can claim it as Underdog bonus funds. Remember, the starting amount of $1 million is a virtual balance, not real money you can withdraw.


Underdog App Review

With a sleek mobile app that features bold branding, easy-to-navigate menus, and reliable technology to keep your personal and financial details secure, the Underdog app is one of the best on the DFS market.

The Underdog app is available for Android and iOS devices through the Google Play Store and Apple App Store respectively, but using the links on this page is the easiest way to get started. Underdog has a 4.8-star rating on the App Store and players are clearly enjoying everything this DFS app has to offer.

Underdog App

Overall, Underdog offers one of the best daily fantasy sports platforms on the market.

Whether youโ€™re a rookie DFS player or a seasoned pro, youโ€™ll have a lot of fun with Underdog. Backed by investors like Kevin Durant, Mark Cuban, Adam Schefter, Scott Blumstein, and The Chainsmokers, Underdog is a reliable and trustworthy DFS operator

Pros:

  • Transparent rake that shows you how much Underdog is taking from each contest
  • Variety of games like Pickโ€™em, Snake Drafts, Battle Royale, Rivals, and Best Ball contests
  • Intuitive mobile app
  • Enticing promotions

Cons:

  • Limited number of payment methods and withdrawal options

Positions Filled Requirements

One of the best features at Underdog is their transparent rake, which is displayed when you enter a contest. The rake is the percentage of the prize pool Underdog collects once all contestants have paid their entry fee.

Building your fantasy rosters at Underdog is a process players will enjoy as positions filled requirements allow for flex and super flex entries. The positions you need to fill can differ depending on which contest youโ€™re entering and thereโ€™s a two-team rule that requires you to include players from at least two different teams for all major league sports.

In Underdog football NFL contests for example, daily contests allow for one flex (RB or WR) position entry, and a single-game roster allows four super flex positions (QB, RB, WR, TE, K). Best Ball entries allow four flex entries and 10 bench positions, while playoff Best Ball rosters are comprised of four flex positions and five bench players.


Games and Contests at Underdog

The selection of Underdog contests will keep you locked in with the action no matter which sport you like to compete in.

Hereโ€™s a quick list on some of the most popular Underdog contests and short descriptions of each:

  • Underdog Best Ball โ€“ Contestants select players through a snake draft for a season-long contest, and Underdog automatically selects the entrantโ€™s highest scoring players at the end of each sportโ€™s week.
  • Pickโ€™em โ€“ Select between two and five players and decide if they score higher or lower on certain fantasy stats. If you get five picks right, youโ€™ll earn 20X your money. These higher/lower fantasy stats are similar to over/under player props in sports betting.
  • Rivals โ€“ Contests where players pick two or more fantasy statistics (goals, points, rebounds, passing yards, etc.) to build an entry. For example, LeBron (+2.5) points vs Kevin Durant.
  • Battle Royale โ€“ Entrants select players through a snake draft, with the size of the snake draft group varying between contests. Compete against all entrants for one week as opposed to a select group.

Scoring systems for fantasy points can vary depending on which sport and what contest youโ€™re playing. Underdog offers DFS markets for all major league sports, along with alternative options like PGA an eSports contests in certain regions.

Whether youโ€™re looking for daily drafts, Best Ball drafts, weekly Battle Royales, or contests across a whole season, Underdog has you covered. Nowโ€™s a great time to jump in on daily and weekly contests in the thick of the NFL season or MLB playoffs, while season-long entries for the start of the NBA and NHL year currently present some huge opportunities. Their biggest contest, Best Ball Mania III, has been filled with 451,200 teams.

Daily contests typically range in size from 3-12 fantasy managers, with entry fees coming in at anywhere between $3 and $100.

Entry Fees, Payouts, and Prize Pools

Entry fees, payouts, and prizes also differ depending on what Underdog game youโ€™re playing, but with their transparent rake system, you can easily keep track of your wins and losses.

Best Ball Mania III is currently offering up $10 million in total prizes, with a $2 million going to the first-place winner in the biggest tournament Underdog has ever offered.

When it comes to Pickโ€™em contests, the more players you add, the higher your potential payout. Selecting the correct higher or lower stat for two players will double your stake, three correct picks will 6X your money, four accurate choices will earn you 10X, while the maximum five player picks will 20X your entry.

You can find all the details on entry fees, number of entrants, total prizes, rankings, and Underdogโ€™s rake on each contest. Underdog offers plenty of details on its contests, whichall players will appreciate.

Underdog Rips: Digital Sports Card Packs Explained

Underdog has expanded its in-app offerings with Rips, a digital pack-opening experience built around real sports trading cards. Instead of buying a pack at a store, users purchase and open packs directly in the Underdog app. Each digital pull represents a physical card held in a secure vault.

One useful feature lets you review a pack’s odds and eligible card tiers before opening it. This gives a clearer picture of possible outcomes, though it doesn’t guarantee a valuable pull. Pack odds can also change as other users open packs.

How to Open Underdog Rips

To find Rips, navigate to the Games section of the Underdog app. Browse the available packs, check their prices and listed odds, and select a pack if you decide the likely outcomes justify the cost. Your card is revealed digitally as soon as the pack opens.

Once the card appears in your account, you can choose how to handle it:

  • Keep it: Retain the card in your vault collection.
  • Ship it: Request physical delivery to your home.
  • Sell it back: Receive the displayed fair market value through the in-app process, subject to the applicable terms.

Rips adds a collectibles option to Underdog’s broader sports-focused platform. However, users should evaluate it separately from traditional fantasy contests. A card’s market value can fluctuate, and the amount offered for a card may be lower than what you paid to open the pack.
