When social casino sites like Underdog-Fantasy want to up their customer base, while at the same time looking after the existing players they have, they will use bonus schemes and promotions. And sometimes those bonuses will come in the form of a sign up bonus code that gets you more from the site right at the very beginning.

So let’s have a look at the bonus code on offer at Underdog-Fantasy today, as well as their other promotions.

Refer A Friend Bonus

Another great way to gain yet more free bonus coins at Underdog-Fantasy is to get your friends in on the action. By simply referring any of your friends and getting them to sign up and play, you will put yourself in the running for a great bonus prize. But what do I need to do to make the most of this promotion? I hear you ask. Well that’s where I come in. I have done the work so that you don’t have to. Here is what I found out.

Start / End Date

Although there is technically no start or end date to this promotion, it can be stated that the bonus offer starts once a referral is eligible and ends when the bonus has been rewarded.

How Do I Get My Referral Bonus

The friend referral bonus scheme is very useful as long as you know how to qualify for it. Many players have missed out on this offer as they didn’t know how to benefit from it. Luckily for you, I have done a deep dive into the bonuses offered at Underdog-Fantasy so that you don’t have to. To get started all you need to do is:

  1. Download the Underdog-Fantasy app from the App Store or head to their website online.
  2. Sign up as a new player or login to your existing player account.
  3. During the application you will be given a referral code to give to friends.
  4. Ask a friend to sign up as a new player using your referral code.
  5. When that friend has been verified, approved and has placed a deposit, you will receive your bonus.

What You Get For Referring A Friend

The whole point of a bonus offer like this one is for Underdog-Fantasy to get new players on board. But it’s also a way to reward existing players for bringing in those new recruits. So what is it that this site offers you for adding your friends to their roster? Well, as long as the new player uses your referral code and signs up completely, then once they have made a deposit of $10 or more, you will receive:

  • $10 credit of bonus cash to your account.

Restrictions

The rules of this bonus offer state that the referred player must make a deposit before the bonus is issued. The original player must then playthrough this bonus cash before it can be withdrawn. All players involved must be 18 years of age or over and be playing from a non-restricted state.

Multiplier Boost Promotion

As if matching 50% of your first deposit and then giving you more to refer a friend was not enough, Underdog-Fantasy have gone one step further. They have come up with another way to reward regular players who have an eye for outcomes. The new Multipier Boost promotion they are running means that if you can guess how certain athletes will perform, then you will be in the running for some significant wins.

Start / End Date

This bonus offer does not have a start or an end date attached to it and is available to both new and existing players who meet the eligibility requirements.

How To Get Your Multiplier Boost

Once you have completed your sign up process and have been able to start playing, one of the next ways to get more for your money is through the use of this Multiplier Boost promotion. But is it easy? And what do you need to do to get it? Here are the simple steps I took to get involved.

  1. Find Underdog-Fantasy online or download the app.
  2. Login to an existing player account or set up an account as a new player.
  3. Make an accurate prediction on the performance of certain players.
  4. Once two or more of those predictions are correct you will be issued with your bonus.

What Does Multiplier Boost Get You?

When you have completed all the steps necessary to become eligible, there could be a Multiplier Boost waiting for you. But now you know how to get involved, what is it that you get from this promotion? That’s simple. Here’s how it works.

  • Make two correct outcome predictions and gain a 3x bonus (depending on the odds).
  • Make five correct outcome predictions and gain up to 20x bonus (depending on the odds).

Restrictions

In order to meet the terms and conditions attached to withdrawal of this bonus, players must playthrough their winnings once beforehand. Bonus depends on the odds at the time of making their picks. Players must be 18 or older (unless the player state requires more).

Online Feedback

The reviews left online by other players of a social casino site like Underdog-Fantasy are usually the best way to know how good it is. These reviews will also point out the negative points as well as the positive ones. Let’s see what the online player community makes of Underdog-Fantasy.

underdog fantasy promo feedback 1

In truth, this is one of the worst star ratings that I have ever come across for a site like this. 1.9 on trustpilot is a pretty damning review. The fact that there are only 13 reviews and they are all negative really does say a lot.

So why all the negativity? Let’s hear what the players themselves have to say.

underdog fantasy promo feedback 2

A player called Dillon McCracken seems to have had a very negative experience playing at Underdog-Fantasy. He claims to have been playing at the site for several months and says that everything was normal until he was a few picks away from winning 10,000 on streaks.

It was at this point when he had his account closed and a message saying that he had been ‘banned for collusion’ with no explanation.

underdog fantasy promo feedback 3

Another unhappy Underdog-Fantasy customer has placed another one star review after their experiences. The problem faced by a player called John S was that having missed only one pick out of seven, the prize went from $874 down to just $32.

So it would seem that players are not happy with the amounts that they win even when they do.

Requirements For Redeeming

In order to be eligible for redemption of any bonus prize from Underdog-Fantasy you need to be 18 years or older in most states. Over 19 years old in Colorado, Alabama and Nebraska. And over 21 in Arizona and Massachusetts. Players will need to meet the playthrough requirements before redeeming.

Playthrough Requirements

While some sites of this type ask for a player to play through their winnings upto three times before they are allowed to redeem them, Underdog-Fantasy asks for far less. There is only a 1x playthrough required by any player before they can redeem a prize.

So if a player wins $10, they must play through that $10 before they can redeem any winnings.

Underdog-Fantasy Overall.

From my extensive look into this social casino site and app I can see that there is a lot of room for improvement.

While the bonus code offers a good prize to new players and some of their other bonus schemes offer free coins to existing players, there is a large amount of evidence against Underdog-Fantasy being worth the while.

The reviews from unhappy customers cannot be overlooked. In my opinion, there are better sweepstakes casinos out there.
