• Free picks for contest entries
• Vulture Protection: triggers when a backup football player takes away a touchdown from a star player. For example, if the Eagles gave the ball to Will Shipley at the 1-yard line instead of Saquon Barkley and Shipley scores, he "vultured" Barkley's touchdown.

Underdog states: Where is Underdog legal?

Different laws apply to fantasy sports and sports betting, with states differing on what DFS apps like Underdog can offer to users. Laws protecting fantasy sports have never encompassed a single format of contests. 

Federal law excludes fantasy sports from the law prohibiting unlawful internet gambling. If a fantasy contest satisfies the conditions provided in the Unlawful Internet Gambling Enforcement Act, then it is not a form of "gambling" under federal law.

Here is a breakdown of which types of games are offered on the Underdog app in which states: 

Is Underdog legit?

Yes, Underdog is a legitimate DFS platform. Underdog holds all licenses and governmental permissions necessary to offer our contests, including licenses and permits for fantasy contests in every state that requires them, many of which reviewed Underdog contests as part of the licensing process.

Again, federal law excludes fantasy sports from the law prohibiting unlawful internet gambling.

What is Underdog?

There are three categories of games within Underdog fantasy sports: Pick Em, Champions and Drafts. Check the table above to learn which contests are available in your state.

Although Underdog operates in 41 states, including Washington, D.C., and all Canadian provinces excluding Ontario, not all users have access to the same types of contests. So, answering what Underdog is for you depends on your state. 

Pick Em

In Underdog Pick Em, you are presented with a menu of player stat projections, and you build an entry by choosing at least two of those projections to go higher or lower. An entry must have a minimum of two players from two different teams. Each player can be used only once in an entry. For example, a user cannot pick "LeBron James points" and "LeBron James rebounds" in the same entry.

How much money you could win depends on the type of payout you choose. One interesting feature is Flex payouts. As users add more legs to their entries, they get higher payout multipliers. However, depending on the number of legs, it is possible for a user to still get paid out with one or more incorrect picks. 

If any leg has a Tie/Void ruling, it just becomes an entry with one fewer leg. For example, if a user has a five-leg entry and one leg is a tie/void, Underdog will now follow a payout structure for a four-leg entry. 

Underdog also has a concept called Rivals within Pick Em, which pits two players against one another in a particular statistical category with an adjustment for one player. For example, a Rivals contest may show LeBron James (+2.5) vs. Kevin Durant points. James would win the contest if he scores the same amount, more, or two fewer points than Durant. Durant would win if he scored at least three more points than James.

Champions

This is like Pick Em with an added twist. In Champions contests, users still create a roster ranging from two to eight players. For each player, the user will also still select either higher or lower on particular stat categories. 

Unlike regular Pick Em, though, the entry is submitted into a tournament with other participants. Each correct selection earns the user Champions Points. The entry with the most Champions Points wins the contest. The payout structure is detailed within the tournament your entry is placed within.

Drafts

This aspect of Underdog is most similar to traditional fantasy sports leagues, where users select players through a snake draft. There are several different formats available for users:

• Battle Royale: You are not only competing against the others in your draft. You also compete for one week against every snake draft group entered into the contest tournament. Yes, you could have the same players as other teams. This makes unique lineup building part of the strategy.
• Sit N Go: competing against the others in your draft only, not against a wider tournament pool of entries. You compete during one slate of games, and no player can be on two different users' teams. 

• Best Ball: the same concept as Sit N Go, but instead of it lasting for one slate of games, you are competing for multiple weeks up through an entire season of games. Once entrants draft, their rosters are set - there are no waivers, substitutions, or trades during the contest period.

The Best Ball concept is appealing to many fantasy players who struggle with lineup decisions and rue incorrect start/sit choices. For season-long Best Ball contests, each team's top scorers are automatically put in the starting lineup, and those points are counted. Participants do not have to actively monitor and set their lineups to get the best possible score. 

In season-long Best Ball contests, there are various scoring settings and payout structures across the best DFS sites. This should affect the strategy for those paying attention to the format.

3 big takeaways after reviewing the Underdog app

1. Massive Catalog of Games: The Underdog platform offers an extensive range of contests for users interested in fantasy sports. This volume doesn't slow down the user experience, though there could be some additional scrolling needed when finding lesser-known players in some sports. There is a search function available for finding players. 
   
   
2. Easy to track entries and scoring: Champions and Drafts sections are straightforward, and it is easy for users to track their contests and monitor their accounts.
   
   
3. Competitive promo code and easy registration process: during the registration process, users can deposit with a variety of methods, and there don't appear to be substantial restrictions like other platforms. Underdog is also offering the largest amount in bonus funds, even if it does require a big investment from users in some states. If you have an appetite for more risk and are willing to invest more money, using the Underdog promo code CBSSPORTS2 is far more appealing than other DFS offers.

Honest feedback after reviewing the Underdog app

Some of the details and differences between contests aren't as clear, especially in the Draft formats. It takes some effort to seek out these details within sub-menus of each contest. 

Underdog has an extensive section for resources and responsible gaming, but the customer support is limited to emails. There's no phone number or live chat feature for customer support, which has become more common across sports betting platforms. That's one area where Underdog could improve.
