The current Caesars Illinois promo code should be automatically populated when you access the sign-up form via the banners on this page. This gets you a 100% profit boost on your next 20 bets, up to $25, after placing a $1 qualifying wager.
Effectively, this doubles your winnings on your next 20 bets, which isn’t half bad. Other online sportsbook bonuses in IL are quite similar, and I therefore enjoyed using this unique offer. So if you want to potentially boost your winnings on the next Bears, Cubs, or Bulls games, stick with me to find out more.
The Caesars bonus codes change regularly, and you can find the latest one by clicking any of the promo banners on this page to access this online sportsbook’s website. Starting August 19th, 2025, at 12 PM EST, new account holders in Illinois have the ‘Bet $1, Double Your Winnings on Your Next 20 Bets‘ promotion on offer, which doubles your winnings on your next 20 bets when you register and place a $1 qualifying wager.
The bonus comes in the form of 20 x 100% profit boosts that have a maximum wager limit of $25 and a win cap of $2,500 when you double your winnings. I’ll get to the T&Cs and cover them in a bit more detail later on, but first, here is the essential bonus info:

Let’s use a real-life example to show you how a profit boost would work in action with this NBA bet:
If you were to bet this with $10, here’s how your returns would look with a profit boost vs a regular bet, were you to win:
| Regular bet | 100% profit boost | |
| Total profit: | $15 | $30 |
| Total returns (stake + profit): | $25 | $40 |
As is the case with all the bonuses offered on our list of all Illinois sportsbooks, there are a few T&Cs to be aware of with this offer. That being said, they are very reasonable, as you will see below:

| Maximum bet with profit boos: | $25 |

Wagering Needed (WR): 1x Deposit. T&Cs and 21+ apply
Before we finish, here are my five top tips to help you win using this bonus:
Don’t cash out your $1 qualifying wager as this will void your bonus, even if you’re offered a great price.
The value of this bonus is that you can double your profit without doubling the risk, so avoid longshots, like betting the Bears to beat the Patriots on the moneyline.
This bonus is ideal for betting the Bears on the points spread or taking the totals (over/under market) in a Bulls game, as you can double the -110 odds but keep the high win probability.
The 14-day time limit for the profit boosts is generous, but it’s still important to keep track of time and make sure that you use your 20 profit boosts before they expire.
Timing when you claim the bonus is important. For example, if you want to use the bonus to bet on the Cubs, you don’t want to claim it more than two weeks before the MLB regular season begins.
In summary, the current promo code will already be applied to the registration form if you access Caesars IL directly via our page. This will get you the chance to double your winnings on your next 20 bets with a $1 qualifying bet.
As well as having a low barrier to entry, this promo ranks high in terms of potential value and is one of the most unique sportsbook offers on the IL market right now. In addition to the sports bonus, there’s also a casino welcome package to take advantage of. New players can claim a $10 sign-up bonus plus a 100% deposit match up to $1,000, as well as 2,500 Reward Credits when they wager $25 or more.
You can get the current promo code by accessing the Caesars Sportsbook in IL via the promo banners in the Caesars Sportsbook reviews at deadspin.com.
The current welcome offer is 20 x 100% profit boosts at Caesars Sportsbook. You can claim this bonus in Illinois by registering and making a first bet of just $1.
The free bet welcome offer is no longer available in IL. Instead, you can double your profits on your next 10 bets if you register and place a $1 qualifying wager.
