NBA Markets for the Underdog Promo Code
- Shai Gilgeous-Alexander (Oklahoma City Thunder @ Brooklyn Nets) – O/U 30.5 Points
- Luka Dončić (Los Angeles Lakers @ Houston Rockets) – O/U 30.5 Points
- Nikola Jokić (Denver Nuggets @ Memphis Grizzlies) – O/U 27.5 Points
- Kevin Durant (Houston Rockets vs. Los Angeles Lakers) – O/U 24.5 Points
- Jaylen Brown (Boston Celtics vs. Golden State Warriors) – O/U 24.5 Points
When I’m scanning the morning line for tonight’s matchups, a few spots immediately jump out. First, we have Shai Gilgeous-Alexander sitting on a high line of 30.5 points. The Thunder star is averaging 31.7 points per game and draws a Brooklyn Nets defense that leaks 115.6 points per game.
Then, we have an absolute heavyweight bout in Houston. Luka Dončić shares that slate-high 30.5-point line and comes in scorching hot for the Lakers, averaging 36.6 points over his last five games. He is going up against Kevin Durant and a stout Rockets defense allowing just 109.8 points per contest. On the flip side, Durant’s line is set at a manageable 24.5 points against a Lakers squad giving up 114.9 points per game.
Finally, if you are looking at the primetime Warriors vs. Celtics game, Jaylen Brown sits at 24.5 points. With Golden State missing Stephen Curry and several other key pieces, Brown has a massive opportunity to feast in front of a rocking TD Garden.
Take Your Bonus to March Madness
Here is the best part: you are not just limited to the hardwood of the NBA. If you want to switch up your strategy and target the college action, those $50 in bonus entries can easily be used for your picks on March Madness. Keying in on specific player projections during the tournament is a great way to hunt down a nice pay day when the brackets get busted.
How to Activate Your Underdog Offer
Getting started is simple. To activate this Underdog promotion, just follow these steps:
- Sign Up: Register your account here. You will need to provide standard personal information, like your name, email, and date of birth, to verify your identity. Most importantly, make sure you enter promo code WTOP during registration to lock in the offer.
- Fund Your Account: Make a deposit of at least $5 using one of the available secure methods.
- Place Your First Entry: Head to the lobby and play a $5 entry. Once that initial entry is placed, you will automatically activate your $50 in bonus entries.
Once you have your bonus, it is time to build your entries. I like to look at two main strategies here:
- Standard Entry: You pick 2+ legs. This triggers the largest payout multiplier, but every single pick must hit to cash your ticket. It is high risk, high reward.
- Flex Entry: If you select 3+ picks, you can choose the “Flex” option. This builds in a great layer of insurance. Even if one of your legs misses, you still receive a portion of the winnings. If you’re stepping up to more sophisticated bets, flexing is a smart way to protect your bankroll while still chasing bigger payouts!
