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:

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

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