Welcome bonus

We will begin our journey into the Underdog Fantasy bonuses and promos with the generous welcome bonus that is available all across the country for new users. As we’ve mentioned in our Underdog Fantasy review, this bonus can be claimed by bettors in every state where Underdog Fantasy is legal, as long as it is their first time creating an Underdog Fantasy account and they are at the legal betting age for the state they are in. The welcome bonus is a first deposit bonus where new customers will receive a 50% match of their first deposit, up to $250 in promo credits. So, to claim the maximum $250 in promo credits, the first deposit would have to be $500.

That’s not even the best part about this generous offer. First, there is no Underdog Fantasy promo code. To claim this offer, players just have to complete sign up and verification, and then make a deposit of more than $10. As well as that, the wagering requirements for this offer are as good as they can be, as the bonus funds only need to be played through once to be eligible for withdrawal, and there’s a 60 day expiry to complete it!

Multiplier boosts

As well as the welcome bonus, Underdog Fantasy also offers a great Multiplier Boost promotion within its higher/lower bet picks, where players can achieve significant payouts the more that they correctly guess how certain athletes perform. The more correct predictions made means there is a greater potential payout. By successfully guessing two outcomes there is a 3x payout, but by correctly predicting five, players could get up to a 20x payout, depending on the odds.

With the Multiplier Boosts, any winnings that are over the standard multiplier are awarded as bonus cash, and these bonus funds must be wagered once before they can be withdrawn. For instance, if a Pick 'em Boost offers 50x for correctly predicting five outcomes, and the regular return is 20x, the extra 30x would be given as bonus cash. Pick’em is currently available to be played in AL, AK, AZ, AR, CA, CO, DC, FL, GA, IL, IN, KY, MA, MN, MO, NE, NH, NM, NY, NC, ND, OK, OR, RI, SC, SD, TN, TX, UT, VT, VA, WV, WI, WY.

Refer-a-friend bonus

Another Underdog Fantasy bonus that is available to players is the refer a friend bonus. This bonus reward can see players from selected states receive up to $125 in bonus cash for every friend that they invite who makes a deposit. To participate, you won’t need an Underdog Fantasy promo code, but instead players will receive a unique referral code that their friends can use when they make their first deposit. Like all the bonuses at Underdog Fantasy, the funds have a 1x playthrough requirement, and they expire after 60 days. This referral program works in a similar way to that at other platforms. For example, you can use your exclusive ParlayPlay promo code to refer your friends to the site and claim additional rewards.

More matched deposit bonuses at Underdog Fantasy

The good news is that Underdog Fantasy won’t stop at just putting on one matched deposit bonus. We noticed that the brand had recently upped its game to put on yet another matched deposit promo for new customers.

It’s a deal that could boost your opening deposit by 50% up to $1,000 to use across the brand’s fantasy sports contests.

Just note that you will only be able to get this deal in select states, you have to make a minimum opening deposit of $10, and use the relevant promo code listed on the Underdog Fantasy site. You will also get just 60 days to make use of this special offer. Similar to when claiming the DraftKings Daily Fantasy promo code, we would recommend that you check the banners on this page for the best promotional offers available in your jurisdiction.

Plenty of additional promotions to enjoy at Underdog Fantasy

We found that Underdog Fantasy has an excellent variety of promos for existing customers. As well as the above referral bonuses and multiplier boosts, you could enjoy getting some of the following deals:

Pick ’em Cashback promos

Here you can get a percentage of your Pick ’em entry fees refunded with bonus credit. Normally you would get 5% playback on all of your entries.

Let’s take an example of how it could work. You could spend $200 on some Pick ’em DFS gaming which could mean that you get $10 in bonus cash. We’ve also found similar offers when claiming the FanDuel Fantasy promo code.

Rookie Fever

These are great promos that tend to turn up for specific sporting events for a limited amount of time. Let’s take an example for the WNBA.

Here you just have to add any WBNA player who has the flame emoji next to their name to an ALL-WNBA Pick ’em contest and doing so could increase your potential payouts by at least 10%.

The good news here is that this boost comes in the form of instantly withdrawable cash rather than site credit, and you should get your extra winnings by 3pm EST the next day. Plus with no limit on the amount of entries you place, it should give all sports fans a little extra rookie fever.

Money back guarantee

This isn’t a regular bonus as such, but it’s still a nice gesture from Underdog Fantasy. It basically means that you could get a refund of up to $100 in your first contest. You’ll need to have closed your account to get your deal and need to offer proof of why you are dissatisfied with your experience. Plus it’s worth noting that this deal can only be claimed within 48 hours of you entering that contest.
