Keep Your Million & 50% Deposit match up to $1000 in bonus funds
Below are the rules for the Keep Your Million contest.
Keep Your Million is Underdog's free-to-play survival game. Every eligible customer will receive a virtual $1,000,000 pot in bonus funds. Here are the steps for how it will work:
Step 1 – Pick a question
Ex: will Patrick Mahomes throw for Higher or Lower than 275 passing yards?
Step 2 – Split your million
Drag a slider to divide the pot between Higher and Lower. You can go 100% on one side, split it 50/50, or anything in between. All the money has to go somewhere.
Step 3 – Lock it in
Once you submit your pick before the game starts, it's locked. You can't change it.
Step 4 – Keep your winnings
When the game settles, keep whatever you put on the winning side. That amount becomes your pot for the next question.
Step 5 – Run it back
Make a pick for up to 20 questions. Survive all 20 and cash out whatever's left in Underdog bonus funds.
New users must make a first-time deposit before gameplay; existing users may be required to make a qualifying deposit. Milly Bucks have no cash value and are not withdrawable. Selections must begin within 21 days of becoming eligible and all 20 questions must be completed within 60 days or the game expires and is settled as a loss. Any Milly Bucks balance remaining after all 20 questions is awarded as Bonus Entries, up to $1,000,000. No award is issued if the balance reaches $0.
Underdog also offers a wide variety of games for its users, including Best Ball, Battle Royale, Pick Em and Champions. In Best Ball, you draft a team and only your top scorers are designated as "starters," so you don't need to sweat making an ideal lineup or whether a bench player will outscore a starter. These are conducted via "snake draft," and the prize pool is issued to the highest scorers based on the league's rules.
Battle Royale is a tournament-style contest, where you're not just going against the other teams you drafted with, but your entry is entered into a larger pool of teams. That means you may have teams that have some of the same players, and your score is matched up against every team in the pool rather than just those that you drafted with.
Underdog also has Pick 'Em contests called "Rivals," which are head-to-head competitions between two players based on a stat category like points or yards. For example, it may be picking between LeBron James and Kevin Durant points scored. There may be an adjustment, such as James +2.5, which means for a James pick to win, he would need to score more than, equal two, or one or two points less than Durant. If Durant scores more than three points more than James, users who backed Durant over James would win. There are also Champions contests, which is where players create a roster of 2-8 athletes from at least two different teams. For each athlete on your roster, you predict whether they will go higher or lower than a benchmark stat. For instance, you may be deciding whether or not Christian McCaffrey eclipses 75.5 total rushing yards as one of your picks. Once you submit your roster, you're entered into a tournament with other participants. Correct selections earn "Champion Points," and the player with the most points wins.
DraftKings Pick6
At DraftKings Pick6, when you spend at least $5, you receive $50 in bonus picks and a Sunday gimme pick.

Users on Pick6 make predictions on how players will perform in certain statistical categories to build an entry. Each entry must have at least two picks and feature players from two different teams. There is a maximum of six picks for each entry.
You can only select a player once in your entry. For example, if you were to predict Shoehei Ohtani to go above his projected hits, you cannot pick Ohtani for any other statistical category in the same entry.
Users also cannot make picks across sports for their entries. As you build your entry, the payout multiplier shows you your potential winnings. Each additional pick adds to the multiplier.
The sports currently available on Pick6 are NFL, NBA, NHL, MLB, PGA Tour golf, Soccer, UFC, WNBA, NASCAR and Valorant (Esports). College football and college basketball are available in every state except Arkansas, Indiana, Massachusetts, New Hampshire, Tennessee and Vermont.
ParlayPlay
ParlayPlay matches your first deposit by up to $100, meaning if you deposit $100, you will then have $200 to use with the platform.

The standard format at ParlayPlay is a higher/lower game where you choose whether a player will exceed or fall short in a statistical category. For example, users may have to pick whether Saquon Barkley will rush for more or fewer than 85.5 yards. You can choose up to seven players for these contests, which increases your score multiplier.
Combos is a format that takes a pair of athletes in the same sport and the user chooses whether or not they will combine to meet a statistical threshold. For example, it may take two quarterbacks and the user will choose if they think they will combine to surpass a total amount of passing yards. Say, for instance, the two quarterbacks are Patrick Mahomes and Josh Allen. Users may have to pick whether they believe those two will combine for more than 480.5 combined passing yards, or if they'll cumulatively finish below that mark.
ParlayPlay also runs a number of free-to-play contests that don't require an entry fee. Users, like in the standard format, choose whether players will go higher or lower in different categories. The better you do, the higher you are on the leaderboard, which increases the chances of you winning prizes.

Our favorite DFS apps
SportsLine DFS expert Mike McClure believes Underdog is the best DFS app, giving it high marks for its "clean design, quick entries and Best Ball drafts."
"Underdog feels like the most polished app of the bunch. It loads fast, looks great, and is super easy to use. The Pick 'em section is packed with player props across all the major sports – football, basketball, baseball, golf, and more. You can mix picks across different games and sports, and the app makes it really simple to build an entry in seconds," he said.
McClure also lauds Underdog's Best Ball Drafts, saying it gives the platform a "long-term fantasy edge that the others don't quite match."
"If you want both quick props and seasonal draft formats in one place, Underdog's hard to beat," McClure said.
