Underdog welcome promo code – Make your first deposit count

Underdog welcome bonus

As one of the best daily fantasy sports sites, Underdog pays special attention to its welcome bonus. I was impressed by its simple structure and value.

One of the most important things you should remember about it is the Underdog promo code used when you deposit for the first time. You can see the latest promo code on the Underdog website.

Basically, you’re looking at a welcome bonus offering up to $1,000 to first-depositing users. The precise value depends on the size of your first deposit. This deposit bonus is easy to claim and includes fair requirements. Check my overview below to learn what it brings.

• This 50% deposit match bonus of up to $1,000 is applied to your first deposit.
• You can use it on any Underdog contest, including Best Ball, Pick’em, and Battle Royale/Daily Drafts.

This is an ongoing promotion that is available to all Underdog users. The wagering requirement of 1x tied to this offer is more than reasonable. So, if you deposit $100, you’ll receive $50 in bonus entries, which will give you $150 in contest entries.

On top of that, you have 14 days to complete the requirements. Another thing I like about this deal is that you can deposit as little as $10 and still benefit from it.

Overall, Underdog has one of the best welcome offers on the market.

How the Underdog welcome bonus works

Not all welcome bonuses at daily fantasy sports platforms have promo codes. For instance, there’s no Vivid Picks promo code. However, Underdog decided to include a promo code in this offer. You can use one of our links to visit the Underdog website – the latest promo code will be displayed on their home screen. Use it to take advantage of the signup deal.

Below, I’ll share a few tips and facts to help you determine whether you can use this bonus and how to use it.

• Eligibility. Only US bettors who are 18+ (19+ in Alabama and Nebraska and 21+ in Arizona and Massachusetts) can claim this welcome bonus. Additionally, the Pick’em contests are restricted in some states. Our in-depth Underdog review covers these things in detail.
• Sign up at Underdog. Use one of our links to visit the Underdog official Underdog site. After that, use the black ‘Sign Up’ button, provide the requested information, enter the promo code and register.

Underdog Tournament

Underdog wouldn’t enjoy the same level of popularity if it weren’t for its bonuses for regular bettors. So, daily fantasy betting fans can take advantage of a wide range of promotions on this platform. I’ll list the most essential Underdog bonuses, besides the welcome bonus, below:

• Play Pick’em, Get Cashback. A percentage of the Pick’em entry fees is returned to eligible users during promo periods. They can expect these returns in Fantasy Bonus Entries. For instance, they can expect a 5% NBA Playoffs Playback Program offer.
• Free pick promotion. With the help of this promo, customers can place a free entry into a Champions contest worth $1. These are not paid entries.
• Pick’em rescues. Whenever a player plays in the first half of the match but doesn’t return in the second half, your entry will be refunded regardless of the reason. Remember to choose ‘high’ on the player’s selection to get an opportunity like this.
• Supercharge. With the supercharge promo, you can apply a Boost to eligible Champions and Pick’em entries only after submitting the entry.
• Refer-a-friend. Another excellent Underdog promo is the refer-a-friend promotion. It lets Underdog bettors get bonus funds by referring new users through their unique link. New users must deposit at least $10.
• Thursday 30%. Regular users should mark Thursday in their calendars. Underdog lets you apply a Thursday 30 Token to qualifying entries to boost your winnings by 30%.

The list of bonuses and promotions for existing users at Underdog is pretty impressive. However, experienced bettors will probably notice the absence of a loyalty program. There’s no information on whether a tiered program might appear on this platform in the future.
