Underdog Fantasy Bonus

So whether you’re eyeing those spicy NBA player pick’ems, building a slick NFL draft, or just want to test your fantasy skills for real cash, this bonus gives you more ammo to fire your shot. Let's break it all down.

🎮 How the Bonus Bets Work

Now here’s where you need to play smart. Bonus funds are considered “promotional credits,” which means they’re meant to be used as entry fees into contests — not cashed out directly.

Let’s say you deposit $100 using code TRUSTNBET:

- Play minimum $5
- You’ll receive $100 in bonus funds 
- You’ll now have $200 total to play with

💥 Pro Tip: Use Promo Code "TRUSTNBET"

If you’re serious about snagging this deal, don’t forget this one key move: Use promo code TRUSTNBET when registering.

This unlocks the full bonus funds. Without it, you won’t be eligible, and there’s no way to add it afterward. It’s your ticket to the $100 bonus funds — simple as that.

For more bonus offers just take a look on our Sportsbook bonus overview.

Bonus Availability by State

Underdog Fantasy isn’t a traditional sportsbook, so it’s allowed in more states — even where standard sports betting is off-limits.

From the legal states map, here’s the deal:
- Most states allow some or all Underdog game types
- You must be 18+ in most states (19+ in AL, NE; 21+ in AZ & MA)
- States like New Jersey, New York, Michigan, Pennsylvania, Maryland and Ohio allow Pick'em and Drafts - you are not entitled to this bonus in those States!
- Some states don’t allow Pick'em games — check the map before diving in

🧠 Example: How It All Works in Real Life

Here’s a scenario so you can visualize it:
- You sign up with TRUSTNBET
- You deposit min $10
- Play for only $5
- And get $100 in bonus funds
- You enter a Pick'em contest with $10 of your bonus
- You hit on your picks and win $60

That $60 goes into your real money balance. You continue using your bonus funds for other contests until you’ve played through all $100 within 14 days. At that point, all winnings are fair game to cash out.
