Underdog Promo Code THEGAMEBET: Complete Overview

On Thursday, we see the Celtics meet the Wizards, and we’ve managed to secure an exclusive bonus with Underdog that will get you off to a flying start. With just a $5 entry, you can claim $100 in bonus entries. Let us show you how.

First, you’ll want to make a note of our exclusive bonus code, THEGAMEBET. From here, you’ll want to click on the links in this guide, head on over to Underdog, and work through the sign-up form.

Once online, you’ll need to verify your details, make a qualifying deposit of $10, and begin filtering through upcoming selections for the Celtics vs. Wizards game. After making your picks, submit a $5 entry, and wait for things to result. Within 48 hours, you’ll then find $100 in bonus entries ready to enjoy.

Early Payout Specials And Boost Builders For NBA: Celtics - Wizards

The Wizards are dead last in the East conference, and were victims of a pretty heavy defeat (119-86) at the hands of Indiana. Just about every stat table sees the Wizards at or near the bottom, so it would be fair to suggest that the Celtics go into this game as the favorites. A recent Jaylen Brown triple-double and 42 from Pritchard will strike fear into a leaky Wizards defense, and if this form remains, we could have some big points on the board come the final whistle. Our picks are as follows:

  • Celtics spread -12.5
  • Jaylen Brown over 28.5 points
  • Celtics team total over 122.5
  • Alex Sarr points and rebounds over 26.5
  • Wizards team total under 101.5
