Keep Your Million starts eligible users with a virtual $1 million balance, known as Milly Bucks. You’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 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 player’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 promotion’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 Milly Bucks are promotional funds and cannot be withdrawn or used outside of Keep Your Million.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.

Underdog App

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

Whether you’re a rookie DFS player or a seasoned pro, you’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 Pick’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 you’re entering and there’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.

Here’s a quick list on some of the most popular Underdog contests and short descriptions of each:

• Rivals – 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 – 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 you’re playing. Underdog offers DFS markets for all major league sports, along with alternative options like PGA an eSports contests in certain regions.
