Underdog Fantasy Regular Promos
DFS site Underdog Fantasy NJ spreads a range of tournaments and easy-to-play contests across its online and mobile platforms. Sports include NBA, MLB and NHL. The beauty of Underdog is that you’re saved from setting your lineups: you can use the Best Ball option to just draft a team. Underdog will automatically set the best lineups for you every week.
Tournaments: Speaking of the Best Ball, this format provides the biggest prizepools on the Underdog site. For example, Best Ball Mania III was introduced for the 2022 NFL season. For a $25 entry, you can take a shot at a share of $10m in prize money. Best of all, the highest-scoring team receives a cool $1m.
The beauty of the Underdog model is that every player only gets one lineup. There’s no way for a casual player to get crushed by a semi-pro or pro stacking the odds in their favor with 100 different lineups on a single game.
Refer-a-Friend: You earn $10 to play on Underdog Fantasy just for inviting a friend who deposits into their account. You’ll be provided with a referral link which you can email to friends. Your friend can also take advantage of the $100 welcome bonus when they register and make a deposit.
Alternatively, you can play with Monkey Knife Fight.
