BetRivers have some of the biggest sign up promos out of all of the sportsbooks so if you don't have an account you can cash in big time for the NFL Playoffs.
I personally use BetRivers regularly because they have competitive lines for certain markets and, like I always say, you should have as many accounts as you can so you can shop around for the best line or the best odds to gain an edge on the books.
Depending on the state you're in (or near) you can get a welcome bonus up to $500 - check out what you can get below!
If you don't see any promo below that means you're in a state where BetRivers currently aren't active.
