The top 3 fantasy sports welcome offers compared

I don’t know about you, but I love a good fantasy sports welcome offer. It doesn’t matter if you’re interested in fantasy NBA, NFL, NHL, or golf, getting a little extra something to get you started is never a bad thing.

That’s why I’ve picked three of the best DFS sites for March 2025 based on their sign-up bonuses. I’ll begin by providing a direct comparison of the offers, but will then dig a bit deeper into how they differ based on my real-life experience.

Ultimately, the goal is to help you to select the right DFS site and welcome promo for you.

Underdog Fantasy - 100% up to $1,000

Underdog Fantasy: Pros & Cons

• Daily and weekly contests
• Exclusive welcome bonus
• Impeccable usability on mobile
• Social community available
• Fair bonus terms

• Few deposit options
• No phone support

Visit Underdog Fantasy

First up, we have Underdog Fantasy, who have recently up their game massively with their sign-up offer. If you register today, you can get a first deposit match of up to $1,000 in bonus cash. This is by far the biggest DFS welcome promotion available in May 2025, but how do the T&Cs compare?

Firstly, their minimum deposit is just $10, which makes the bonus very accessible to casual players, as well as those who can afford to claim the full $1,000 bonus. One important thing to highlight is that the exact bonus T&Cs can differ in each state, so make sure to read the small print wherever you are before you register.

Parlay Play - 100% up to $100 + $5 free entry

ParlayPlay: Pros & Cons

• Two-part generous welcome offer
• Wide range of DFS contests
• Downloadable mobile app

• No live chat support

Visit ParlayPlay

Next up, we have the 100% up to $100 first deposit match at Parlay Play. Like the Underdog Fantasy offer, this promotion has a $10 minimum deposit requirement. Once credited, your bonus lasts for seven days and is subject to a 1x wagering requirement before withdrawal, which is the same as the Underdog Fantasy promotion.

Consistency is key with this promotion as it is the same in all 24 states (plus Washington D.C.), which covers all locations where Parlay Play is fully legal. If you don’t claim the deposit match, you are still eligible for the $5 in free entries as soon as you sign up.

OwnersBox - 100% up to 100 Owners Bucks + $5 free ticket

OwnersBox: Pros & Cons

• Easy-to-use website.
• Great welcome bonus
• Weekly fantasy contests are consistent
• Multiple game options, like Lightning Lineups

• No eSports

Visit OwnersBox

On the face of it, the OwnersBox welcome offer is exactly the same as the one at Parlay Play. To an extent, this is true, but there are a couple of key differences. In particular, you should consider how the DFS products themselves work.

For starters, OwnersBox is an app-only platform. After you download the app and sign up, you will get 10 owners Bucks straight away. You then must make a first deposit of at least $10 to get your deposit match (up to 100 owners Bucks) plus the $5 free entry. Unlike Parlay Play, these guys won’t give you the $5 bonus until you spend your own money.

Top DFS welcome offers for March 2025 - The T&CS compared

I mentioned most of the key T&Cs of each of these DFS sign-up bonuses above. However, so that it doesn’t get lost in the noise of all the other info I’ve provided, here is a direct comparison of the key bonus terms:

For context - My experience with the bonus wagering

If you take these wagering requirements at face value, there would only be one winner, right? However, in practice that might not be the case, so here’s some context based on my experience.

• Underdog Fantasy vs Parlay Play: These two offers have the same 1x wagering requirement. Underdog Fantasy gives you twice the length of time as Parlay Play. However, it’s important to remember that you can get up to 10x the bonus amount at Underdog Fantasy compared to Parlay Play, and if you claim a deposit match of $100+, you’re going to need that extra seven days in my experience.
• OwnersBox: This wagering requirement is the steepest by far, but you also get almost a full month to use the bonus and play through it 10 times. On top of that, with a 10 Owners Bucks free sign-up offer and a $5 free ticket, it’s also the offer with the most added extras on top of your deposit match.

My summary - Which DFS bonus is the right one for you?

Not yet sure which of the best three DFS bonuses for March 2025 is right for you? Here are my final conclusions to help you decide:

• The Underdog Fantasy first-deposit match is the best offer if you are planning to deposit $100+ thanks to the reasonable wagering requirement and $1,000 maximum deposit limit.
• The 100% up to $100 bonus + $5 free entry at Parlay Play is an ideal option for new or casual DFS players because you get the $5 free entry before making your deposit to try first.
• Finally, the OwnersBox 100% up to $100 Owners Bucks bonus + $5 free ticket is my preferred option on mobile thanks solely to the app-only service that they provide.
