Here’s a brief look at the top Illinois sportsbook promos available in February 2026, including the best Super Bowl betting sites and best World Cup betting sites.

Read our bet365 bonus code page to learn more about the IL sportsbook.

Getting started on your sports betting journey in Illinois is quick and easy. Here are the steps that we suggest following to take full advantage of IL sportsbook promos.

1. Pick a welcome offer

With 10 Illinois sportsbooks to choose from, there are plenty of ways for you to get started. Use this page to find the promos that suit you the best.

2. Claim your promo code

Click one of our links to access the offer and start the registration process. Some bonuses are applied automatically, while others may require a promo code. Then, download the sportsbook app from the App Store or Google Play.

3. Create a new account

You can register for a sportsbook online from the comfort of your home, anywhere in Illinois.

Registration requires users to provide personal information, such as a valid driver’s license, but it only takes a few minutes.

4. Verify your identity

You need to upload a photo of your resident ID card to verify your age and location in Illinois.

5. Deposit funds

You now have to make your initial deposit into the sportsbook(s) of your choice.

Most Illinois betting sites require a minimum deposit to claim a welcome bonus. Remember this amount to ensure you remain eligible for your new-user offer.

Illinois sportsbooks accept all the popular banking methods, including debit cards, credit cards, bank transfers, PayPal, and more.

6. Place a bet

You’ve registered, deposited money, and are now ready to place a wager. We have found that the best Illinois betting sites make it incredibly easy to track your bets and figure out the amount you stand to profit from a winning wager. Enter your wager amount, review your odds, and click 'Place Wager' to confirm.

7. Enjoy your bonus

As long as your bet qualifies for the welcome bonus, the IL sportsbook promo will be credited to your account. Many bonus bets have a quick expiration date, so keep that in mind.

Can I claim multiple Illinois sportsbook promos at the same time?

Yes, there is no limit to the number of IL sportsbook promos that bettors can claim. The only requirement when claiming a welcome bonus is that it’s your first time registering for the sportsbook. One piece of advice we can offer is to register for only one or two at a time. The promos expire as early as one week, and you don’t want to feel rushed into hasty wagers to clear the terms of the promotion.

Who can claim an Illinois sportsbook promo?

Any qualified Illinois bettor can claim the promos at IL sportsbook apps. The only requirement beyond the necessary legal parameters is that a bettor must be registering for a sportsbook for the first time. For example, even if someone registered for a sportsbook in New Jersey, they will not be able to claim the bonus in Illinois.

There are several reasons behind a sportsbook’s decisions regarding its welcome bonus. Among them may include the timing of a big event such as the Stanley Cup Playoffs. With so many fans tuning in to large events, sportsbooks may look to capitalize on the increased interest and desire for personal investment. These events could influence the timing of promotions, the promo bonuses offered, and several other factors.

Are there any hidden fees or conditions tied to IL sportsbook bonuses?

No, there are no “hidden fees” per se. However, bettors need to understand that certain terms and conditions can affect the value they derive from an IL sportsbook bonus. A primary one is that the bonus expires after seven days. It’s smart to be ready to wager when you register for an app. Secondly, it’s important to remember that bettors do not receive the stake of a bonus bet, only the winnings.

Can I use IL sportsbook promos for live betting or parlays?

Generally speaking, yes. However, it’s essential to familiarize yourself with the terms and conditions of each individual IL sports betting promo, as there are fine details that are crucial to be aware of before making a qualifying wager.
