After signing up and claiming this welcome offer, it is time to dive into the app from there. There are two types of entries you can make on Underdog, a standard entry and a flex entry.

NBA Promotions on Tuesday via Underdog
Underdog has provided a ton of different fun ways to get in on the action. Right now, there are two separate profit boosts you can use on the NBA tonight, while also diving into the different types of entries as well:
- 50% NBA Profit Boost: Place a 3+ leg entry on the NBA tonight, and boost the payout by 50%.
- 60% NBA Profit Boost: Same logic as the above promotion, just with an even higher payout. You can also receive this 60% profit boost on any NBA entry that is 3+ legs.
- Ladders: Choose 3+ players who you think have a chance to go way above and beyond what their prop. There are three legs of the ladder that each player must hit, and you get paid out exponentially more the higher the player climbs. For tonight, we like Darius Garland, Maxime Raynaud and De’Aaron Fox each for their points prop.
- Streaks: Win 11 straight individual player prop entries to 1000x your money. It starts with two player props for you to select higher or lower than, and then you choose one from there.
