  • 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

  • Limited number of payment methods and withdrawal options

Underdog Fantasy Rake

One of the best features at Underdog Fantasy is their transparent rake displayed when you go to enter a contest. The rake is the percentage of the prize pool collected by Underdog Fantasy once all contestants have paid their entry fee.

Beating the rake in the long run can be difficult, and while many major DFS operators like DraftKings and FanDuel are known to hide the rake at times, Underdog Fantasy is very open about showing you how much of a cut they’re taking. This makes the action at Underdog Fantasy feel honest and fair.

Positions Filled Requirements

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 Fantasy 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 Fantasy

The selection of Underdog Fantasy 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 Fantasy contests and short descriptions of each:

  • Underdog Fantasy Best Ball – Contestants select players through a snake draft for a season-long contest, and Underdog automatically selects the entrant’s highest scoring players at the end of each sport’s week.
  • Pick’em – Select between two and five players and decide if they score higher or lower on certain fantasy stats. If you get five picks right, you’ll earn 20X your money. These higher/lower fantasy stats are similar to over/under player props in sports betting.
  • 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 Fantasy offers DFS markets for all major league sports, along with alternative options like PGA an eSports contests in certain regions. College football is another fun DFS market for betting by using an Underdog Fantasy promo code to secure a $100 deposit match.


Whether you’re looking for daily drafts, Best Ball drafts, weekly Battle Royales, or contests across a whole season, Underdog Fantasy has you covered. Now’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 Fantasy game you’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 Fantasy has ever offered.

When it comes to Pick’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 Underdog’s rake on each contest. Underdog Fantasy offers a ton of details on their contests, which is something all players will appreciate.
