Written By Jenn Montgomery on August 3, 2021 - Last Updated on March 9, 2022

Caesars Sportsbook is officially live in Illinois as of Tuesday morning. And, if you haven’t noticed yet, your William Hill app will be asking you for an update.

As we at PlayIllinois learned on Monday, the ongoing acquisition of William Hill by Caesars is finally coming to fruition. The transition should be relatively simple for Illinois sportsbook customers.

Here’s what you need to know moving forward.

FAQ about Caesars Sportsbook in Illinois

Do I need to download a new app?

No. If you already have the William Hill app on your phone, the opening screen will say that an update is ready. After you update the app, it will show 100% Caesars’ branding.

However, if you are a new Caesars customer, you can download the Caesars by William Hill app for Android and Apple devices.


I already have a William Hill account. Now what?

You don’t need to do anything. If you are already a William Hill customer in Illinois, welcome to Caesars. Your account details, including your sportsbook balance, will transfer over. If you have issues or have questions, you can email [email protected] or call 1-866-503-4782.

How do I register for the Caesars Sportsbook?

Ever since the return of in-person registration in Illinois, signing up for a sportsbook can be tricky. You can sign up for Caesars Illinois at Grand Victoria Casino, 250 S. Grove Ave., Elgin.

You can download the app before you go to the casino. Once in the app, you’ll follow the prompts on the screen and should be able to complete your registration easily. One note: You will need to take a selfie that shows you’re in the casino.

If you need personal assistance, someone at Grand Victoria can help you.

Is there a difference between Caesars Sportsbook by William Hill and the Caesars Sportsbook app?

The name is the only difference. Because of the Illinois sports betting regulations, the sportsbook must remain tethered to its retail partner.

Can I bet at Caesars Sportsbook in Chicago?

Yes, once you complete the registration process by visiting the Grand Victoria Casino in Elgin. You can use the Caesars Sportsbook by William Hill from anywhere within Illinois state lines, including Chicago.

Will the Caesars odds be different than the William Hill odds?

No. The lines won’t change. Caesars is keeping the William Hill oddsmakers.

Will Caesars have offers for existing William Hill customers?

Yes. If you are an existing William Hill customer, you are not eligible for the new sign-up bonus. However, the Caesars representatives said there will be plenty of new promo offers for loyal customers. Caesars also offers its highly coveted Caesars Rewards program. So, whether you play at the sportsbook or any Caesars property across the US, you can earn points.

Which properties are Caesars destinations in Illinois?

Whether you dine at a restaurant, stay in a four-star room, play slots or place sports bets, you will earn Caesars Rewards points. Signing up is required. There are more than 50 destinations across the US, including Caesars’ three properties in Illinois:

What happens with the retail William Hill sportsbook?

Caesars spokespersons announced on Tuesday that all retail William Hill sportsbooks are in the process of removing WH signage and of getting all Caesars branding.

William Hill launched in Illinois in June 2020, the fifth sportsbook to go live in the state.
