Sleeper, on the other hand, has a first-deposit match offer going on where a user's first deposit is matched 100% up to $100, meaning you could have a $200 bankroll in site credit after depositing $100 of your own money into your account.

Boom FantasyDFS contests

Boom Fantasy offers a few different formats on its app for users to play, with two of the main types being Classic Pick 'Em and Pick & Spin. Here's a breakdown of how Classic Pick 'Em and Pick & Spin work.

Classic Pick 'Em

Classic Pick 'Em is the standard format that you see on most DFS platforms. At Boom Fantasy, you select two to eight athletes and pick whether they will go higher or lower than a designated stat line. For example, if you were targeting NBA players for your entry, you may select Luka Doncic of the Los Angeles Lakers and Jalen Brunson of the New York Knicks. Both players will have different stat lines for Boom Fantasy users to choose from – say 31.5 points for Doncic or 37.5 total points + assists for Brunson. You would then choose whether they will have more or less than the particular line attached to them. 

Each pick also has a particular multiplier attached to it. The way the payout works is it's your overall multiplier times your entry fee. The more picks you make for your entry, the higher your multiplier is. The maximum multiplier for a single entry is 500x. The Pick 'Em format covers a wide variety of sports and leagues, such as the NFL, NBA, NHL, MLB, WNBA, college football, college basketball, UFC and tennis. 

Pick & Spin

Pick & Spin is a unique twist on the Pick 'Em format that DFS users are accustomed to playing.

Here, you make just two picks as part of your entry and then spin a virtual wheel. That wheel has a few different numbers on it, and whatever the spin lands on is what your multiplier is for that entry. The lowest multiplier on the wheel is 2x, and the highest is 500x. If both your picks are correct, you get your entry fee back times the multiplier from the wheel. Top sports and leagues like the NFL, NBA, NHL, MLB, WNBA, college football, college basketball, UFC and tennis are all available for the Pick & Spin format at Boom Fantasy.

The odds of getting that maximum 500x multiplier with Boom Fantasy's Pick & Spin format are low. How low exactly? Here are the odds of receiving each potential Pick & Spin multiplier.

Ways Boom Fantasy app can improve for DFS players

While it's nice that Boom Fantasy has a rather extensive FAQ page that offers insight into various topics like deposits, withdrawals and game types, some of the pages haven't been updated in more than a year, causing some information to be out of date and not quite match up either with what's available on the app or what a different and newer FAQ page says. 

Boom Fantasy does offer quite a few responsible gaming tools and resources, but it's not as prevalent on the app or site as it could be. Additionally, there's nothing related to responsible gaming available on the Boom Fantasy FAQ site. Customer support options are rather limited, too, with just a live chat and email address as the featured ways to get in touch with Boom Fantasy's support team. Sometimes the quickest and easiest way to resolve an issue is speaking to someone over the phone, so adding that as a more prevalent option would be a welcome addition to the platform.

Boom Fantasy user experience

The Boom Fantasy app provides a great experience for new and experienced DFS users alike. The app works well with easy-to-use functionality. The ability to choose which format you'd like to play is very simple, and making picks for your entries is very simple as well. There's a clear search bar and users can swap between sports, leagues and even different options for specific leagues – for instance, Boom Fantasy offers specific stat lines for quarters or halves of NFL games. 

The gameplay is easy to follow with pick, player and league/sport options very clear. The app also does a good job of making it very clear what your multiplier/maximum payout is for every entry, and it's easy to follow how your entries are performing through the "entries" tab on the app. 

It feels like there are just the right amount of gameplay options at Boom Fantasy as there aren't too many where it could be confusing or overwhelming how many game types there are, but there are also just enough game types to where DFS users can have some versatility in their play time. 

The app does a good job highlighting its main game types and special events, and the "promos" tab on the bottom of the screen is always there, so Boom Fantasy users can always check to see what special offers are going on or are upcoming. 

Boom Fantasy promos for existing users

While the new-user offer for Boom Fantasy is for up to $100 back in site credit if your first entry loses, Boom Fantasy also regularly offers promotions for existing users as well. 

At times, Boom Fantasy will offer deposit match promos for existing users, as well as profit boosts and double XP days. Additionally, the platform often offers athlete discount promos where certain star players will have adjusted stat totals for an upcoming game. For instance, Golden State Warriors star Stephen Curry may usually have his points line set at 24.5. If he's a featured player for a Boom Fantasy athlete discount promo, his points line may be lowered to say 16.5. 

Boom Fantasy also offers a regular refer a friend promotion. With this, an existing user can earn $10 in site credit for every friend they recommend who signs up with Boom Fantasy and deposits $20 or more into their account. To utilize this, users can use the "Invite Friends" link within their Boom Fantasy account profile.

Boom Fantasy banking methods

Boom Fantasy offers a few ways for its users to deposit and withdraw money to or from their account. 

In addition to debit and credit cards, users can deposit funds into their Boom Fantasy accounts through PayPal, Venmo and Apple Pay wallets. The minimum deposit amount is $10.

For withdrawals, Boom Fantasy users can use debit cards, PayPal, Venmo and online banking. The minimum withdrawal amount is $10. 

Is Boom Fantasy legit? 

Boom Fantasy is a legal DFS site and app that is available in 25 states as well as Washington D.C. Boom Fantasy offers safeguards for its users, namely account verification processes. Whenever a user makes a deposit or an entry, they will be tasked with filling out an account verification form to confirm your identity. If that process fails for whatever reason, a user will have to upload a photo ID or need to reach out to Boom Fantasy's support team.

Boom Fantasy responsible gaming

It's important that all DFS users practice responsible gaming whenever making entries on DFS apps like Boom Fantasy. Boom Fantasy has a few different responsible gaming tools and resources available on its platform for its players to utilize.

  • Monthly deposit limits: Users can set a limit on how much money they can deposit into their Boom Fantasy account each month. 

  • Entry fee limits: Boom Fantasy users can limit and control how much they can spend on entry fees.
