Underdog Welcome Offer Explained
A deposit match is a common way for sports betting and daily fantasy apps to get you using their site. The offer allows new users a chance to match whatever funds you put into your account, up to $1,000. After you make a qualifying bet, you’ll be credited with funds, in the form of bonus entries. It is not the same as cash — you cannot deposit $1,000, have the funds matched, and withdraw $2,000. Instead, you will have to play the money before any of it becomes eligible for withdrawal.
Underdog Promo Code Terms and Conditions
- New users only, 21-plus, one per household, in a legal state.
- Minimum deposit $10; qualifying bet $10 at no minimum odds.
- Bonus issued as bonus entries and expires in 7–14 days.
- Bonus bets pay winnings only, not the stake.
- Available in 42 states.
- See the full terms here.
How Underdog Bonus Bets Work
In order to use a bonus fund or entry from the welcome offer, you will need to first deposit into your account. After the deposit is matched, you have to play through the funds before it can be withdrawn. For example, if you deposit $20 and are matched $20, you’ll have to risk $40 on bets in order to withdraw the funds. You can use them for any bet you would like, but there may be restrictions on boosted bets or multiplier boosts.
Ongoing Underdog Promos for Existing Users
While this offer is limited to new users, Underdog also provides promotions for existing users. Underdog has no loyalty program, but users can receive promotional tokens, discounts or multiplier boosts instead of bonus bets. The more you play, the more likely you are to receive these options.
