Pros & Cons

  • Flexible Play: You can use bonus funds across different games and contests
  • Winnings Are Yours: Whatever you win from bonus entries is withdrawable
  • Fast Bonus Credit: Bonus funds are typically credited within 72 hours
  • Not Withdrawable Directly: Bonus funds must be used on the site; they’re not cash

🎮 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:

- You’ll receive $50 in bonus funds (50% match)
- You’ll now have $150 total to play with
- That $50 in bonus credit can only be used to enter fantasy contests
- You have 14 days to use it before it expires
- Winnings from bonus entries are yours to keep and can be withdrawn once playthrough conditions are met

To unlock any bonus winnings, you need to complete 1x turnover (i.e., use the full bonus amount in eligible contests). So if you get $50 in bonus funds, you must use all $50 in fantasy entries before any part becomes withdrawable.

Hint

💥 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 deposit match bonus. Without it, you won’t be eligible, and there’s no way to add it afterward. It’s your ticket to the 50% match — simple as that.

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 Michigan, Pennsylvania, and Ohio allow Pick'em and Drafts
-
Some states don’t allow Pick'em games — check the map before diving in

Example

🧠 Example: How It All Works in Real Life

Here’s a scenario so you can visualize it:
- You sign up with TRUSTNBET
- You deposit $100
- You get $50 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 $50 within 14 days. At that point, all winnings are fair game to cash out.

Conclusion

Underdog Fantasy knocks it out of the park with this generous bonus offer. The TRUSTNBET code adds serious value to your first deposit, giving you more chances to draft, pick, and win.

Is it perfect? Not quite — the 14-day window adds a little pressure — but overall, the bonus is a great way to start with extra firepower.

We rate Underdog a strong 9.2 out of 10 — a top-tier option, especially if you're in a state where traditional sportsbooks aren’t legal yet.

So what are you waiting for? Smash that TRUSTNBET code, make your first deposit, and start building your fantasy bankroll today!
