We’ve written a guide at GamblingGuy to give you the full lowdown on how Underdog Fantasy welcome offers works. We’ve provided details of what to expect from Underdog Fantasy and the pros and cons when using their website. And just as we did in our FanDuel rating, we answer the question whether there is an Underdog Fantasy scam or not too! Of course, we think Underdog is legit, otherwise we would not have written a full article about them! The welcome bonus is a good one too – so be sure to check out our Underdog Fantasy reviews.
