30% Profit Boost for NBA Tonight
Underdog is generous enough to offer users a 30% profit boost every single day of October for their “Boostober” promotion. With the NFL and MLB having no games tonight, it makes sense to use this promotion for the two NBA games tonight.
This boost must be used on a $50 entry max, while you certainly do not have to use that full amount. There are some star-studded matchups tonight with a bunch of big-name players playing.
If you think the stars are going to show out, you could lock in the over points for Steph Curry (over 26.5), Luka Doncic (31.5) and Shai Gilgeous-Alexander (31.5).
