Underdog Fantasy is not a sportsbook, instead working on a unique DFS system. Users create lineups containing players across sports by selecting "Higher" or "Lower" than a player's projected statistical output. This represents an excellent alternative to online sports betting if it is not legal in your state yet.

Use the Underdog Fantasy Promo Code TOPACTION for NBA Lineups Today
The Underdog Fantasy promo code TOPACTION delivers a 50% deposit match of up to $1,000 in bonus cash. Make your first lineup and receive half of the amount, up to $1,000, in bonus cash.
Let's say I make my first deposit at Underdog Fantasy for $2,000. This provides the maximum bonus amount of $1,000 in bonus cash due to the 50% match. There is a 1x rollover for this offer that must be met within 60 days. So with this example, I must place $1,000 in lineups within that time frame to withdraw my winnings.
Now, let's look at a lineup I created for NBA games tonight that works well with the Underdog Fantasy promo code TOPACTION.
- Donovan Mitchell HIGHER than 24.5 Points
- Victor Wembanyama HIGHER than 23.5 Points
- LeBron James LOWER than 8.5 Rebounds
There are two different ways I can place this lineup: Standard or Flex. A Standard lineup provides a 6x payout if all picks win, while a Flex lineup gives out a 3x payout or going perfect or a 1x payout for going 2-for-3.
Suppose I place the lineup for $10 as a Standard entry. If it wins, I get $60 in profit that is distributed as $50 in profit and my $10 stake credited back to my account. If even just one pick loses, I get nothing, but I still work through the rollover requirement.
