NFL season is in full swing, and Week 4 gives sports bettors another reason to check out sportsbook promotions.

But what if you also like online casino games?

Some gambling operators connect their online casino and sportsbook promotions , giving players ways to earn rewards on one side and use them on the other. PENN Entertainment is one of the clearest examples right now with Hollywood Casino and theScore Bet .

And if you’re looking for a casino bonus before the Week 4 NFL slate, Hollywood Casino has an offer worth checking out.

Hollywood Casino and theScore Bet are both part of PENN Entertainment’s online gambling business.

Hollywood Casino promo code handles the online casino side, while theScore Bet is PENN’s U.S. sportsbook. The two are connected through PENN Play , which lets eligible players earn and redeem PENN rewards across casino and sports betting.

PENN currently allows $1 in PENN Cash to be redeemed for $1 in PENN Play Credit for online sports betting , while the same PENN Cash can also be redeemed for online casino credits at Hollywood Casino.

That makes the setup interesting if you regularly switch between slots and NFL betting.
