How Do Illinois Online Casino Bonuses Work?

Bonuses offered by Illinois online casinos are there to give you an incentive to sign up for an online casino account. They hold out the promiseβ€”and should deliverβ€”a chance to enjoy some extra value and fun when you sign up.

The casino promotions Illinois players will be offered come in various forms, and it's always a good idea to check the fine print to make sure you get the full benefit of the offer.

Activating a Bonus

Most of the online casino promotions Illinois operators will offer should be applied to your account automatically once you have signed up and made your first deposit. However, there may be occasions when you have to opt in. This depends on the type of bonus and on the operator.

You should find a selection of online casino promo codes Illinois players can use to trigger a generous welcome offer.

Code or No Code

Most online casinos in Illinois will offer you a promo code for use during the registration process to lock in a bonus. You'll be able to find a code on this site once legal online casinos begin operating in Illinois.

However, some of the best Illinois online casinos will not issue promo codes; and even at the websites and apps that do, you should be able to claim your bonus without using one.

Check the Bonus Expiration

If you check the terms and conditions of a welcome offer for no other reason, make sure you know how long you have to use bonus cash or credit, or free spins, generated by your promotion. You may have only a few days to play your bonus funds at an online casino site, and it is extremely frustrating if you try to use your credit only to find out it has expired.

Understand the Terms

It's worth saying again: Always check the fine print on an offer from any online casino Illinois gives a license to. The bad news is that they vary from operator to operator, but the good news is that terms and conditions should be easy to find.

If, for any reason, you don't understand precisely what you need to do to claim a bonus, contact the customer support team at the casino.

Wagering Requirements

Online gambling sites often impose rules relating to actions you have to take to make sure you qualify for, and make the most of, a welcome offer. Make sure you know if there's a minimum deposit, for instance. And be clear about whether or not you have to play through your deposit (and any bonus funds it triggers) a particular number of times before you can treat your winnings as withdrawable real money.

Always ensure you:

  • βœ… Find out what the minimum deposit is
  • βœ… Understand the playthrough rules
  • βœ… Take all the steps necessary to maximize your bonus

Game Contribution Rates

This is where things can start to get a little complicated. Contribution rates relate to the playthrough requirement on your bonus. Some casino games contribute more than others to that requirement. Please note that the rates can vary between online casinos in Illinois.

So, for instance, at the Caesars Palace online casino, to get your $10 signup bonus you need to play it 1x on slot games, 2x on video poker and 5x on all other games, including table games. But at the FanDuel Casino, on the other hand, all online casino games make a 100% contribution to your playthrough.

Eligible Games

Some online casinos in Illinois will stipulate that a bonus can be used only on a certain game, usually a title that the company wants you to play. This is most often the case when you get free spins; you may have to use them on particular online slot machines.

At the PointsBet Casino, for instance, any free spins generated by your welcome offer must be used on Cash Eruption.

Winning Caps

One of the reasons for checking the terms and conditions relating to offers at online casinos in Illinois is to see if there is an upper limit on your winnings from a welcome bonus. If such limits are applied, it will usually be to free spins and no-deposit bonus offers. Some Illinois gambling operations will impose no cap at all on your winnings.

Restricted Payment Methods

It's in the interest of all online casinos in Illinois to make it as easy as possible to sign up for an account. One way is to offer a wide range of payment methods for making deposits and withdrawals. However, there may be occasions in which particular payment methods cannot be used on deposit bonus promotions. Always check that you are using an acceptable option if you want to claim that bonus.

Types of Online Casino Bonuses and Promotions

Once legal online casino gambling begins in Illinois, leading operators will offer you a host of promotions and bonuses, similar to Illinois sportsbook promos that are already offered in the state. Many are aimed at prospective new customers, in an attempt to persuade them to play casino games online with particular companies.

There are also offers that are designed for existing customers so that they remain happy to stick around to enjoy slot games, live dealer games, and other types of casino games.

Welcome Bonuses

When you open a new account at one of the top online casinos, you should expect to be rewarded with an attractive welcome offer. Some Illinois casinos will distribute promo codes to publicize their offers, and their products generally. Your welcome offer may be in the form of a substantial boost to your bankroll through a deposit match, the chance to get your early losses back, or the opportunity to enjoy free spins at particular online slots.

No-Deposit Bonuses

Many online casinos in Illinois will welcome you with a no-deposit bonus. This means you get money to enjoy online casino gambling before you invest a cent of your own. Offers like this are a risk for the operator. After all, you might play through your bonus and go elsewhere without risking a dollar in real money, which is why they tend to be relatively modest sums between $10 and $35.

Mobile Casino Bonuses

Many people who enjoy online gambling in Illinois do do through their mobile device, and this will not change when the state decides to legalize online casinos. Some of the top online casinos have offers designed exclusively for online gambling fans who use the company's app. If you do your online gambling through your smart phone, look out for these app-only offers.

Free Spin Bonuses

The chance to enjoy bonus spins on particular slot games may be offered by online casinos in Illinois as part of your welcome offer. It's a tried and tested way for operators to increase traffic at certain online slots. Existing customers sometimes benefit from the chance to play extra spins, too, as the casino tries to promote certain slot games.

Reload Bonuses

Real-money online casinos in Illinois will occasionally offer customers the chance to give their bankroll an extra bump. Reload bonuses work in the same way as a deposit bonus; however much you put into your account, the operator will enhance by a certain percentage. Ideally, this is a 100% match, so a deposit of $50 actually boosts your account balance by $100.

Losses Back Bonuses

Some of the leading operators likely to launch in the Prairie State when it makes online casinos legal already offer this as a welcome bonus.

At companies such as FanDuel and BetRivers, you can recoup your overall real-money losses from the first 24 hours of your account, even if you are several hundred dollars down. The losses are credited to your account in the form of bonus funds that can be used over the next few days.

Cashback Bonuses

There are various types of cashback bonuses that may be used by Illinois online casinos. Some of the rewards in a loyalty scheme may be in the form of bonus funds that can be treated as real money when they hit your account. You may also be offered the opportunity to claw back your losses over a certain period, much like the welcome bonuses that relate to your first-day online gambling as a customer.

High Roller Bonuses

Some visitors to Illinois online casinos will have bigger bankrolls than the average online gambling fan. Certain casinos in Illinois will target such customers with exclusive bonuses aimed at the big spenders. Another way in which high rollers benefit is that wagering large sums at Illinois online casinos will move them to the very highest tiers of a rewards program, where the benefits can be spectacular.

Refer-a-Friend Bonus

This is likely to be one of the most frequently available offers when online casinos become legal in Illinois. If one of your friends wants to open an account, you send them a unique referral link. As soon as they make a deposit and start playing, that should trigger a bonus payout for both you and your buddy.

Software-Specific Bonuses

Some Illinois online casinos may offer promotions centered on online slots, table games, and live dealer games provided by particular developers. Look out for bonuses relating purely to titles produced by Evolution Gaming, Microgaming or NetEnt, for instance. If you especially like to play casino games produced by the developer in question, this is a great promo for you.

Monthly Bonuses and Ongoing Promos

All operators offering online gambling in Illinois should maintain the interest and loyalty of their players by delivering fun and value. Look out for free-to-enter tournaments, or contests around certain slots and table games. The prizes can be highly attractive. Stay in touch with ongoing bonuses by checking out the Promotions page of your online casino site or app.

Which Casino Bonus is Right?

As you can see, we can expect online casinos in Illinois to offer a range of attractive promotional offers in an attempt to secure your attention and ongoing loyalty. But which are the best ones for you?

What matters is how you most enjoy playing real-money online slots, table games, and live dealer games. There are some simple ways to narrow down your choice:

  • βœ… If you are intending to play casino games regularly, a deposit bonus that boosts your bankroll could be ideal.
  • βœ… Deposit bonuses are also useful for Illinois online gambling fans who want to diversify and try new online casino games.
  • βœ… When slot games are your favorite destination at online gambling sites, free spins are perfect for you.
  • βœ… If you are a novice when it comes to online gambling in Illinois, make sure you don't overspend on your first deposit. You might generate bonus funds that you do not have time to use before they expire.

You may not want to use any bonus at all but still like the chance to gamble online in Illinois. Whether you activate a welcome offer or not, you should still find plenty to entertain you.

Why Would a Casino Give a Bonus Offer?

If online casinos are legalized in Illinois, you are likely to be confronted by a huge selection of bonus offers. Why do they do it?

There are several reasons why leading brands will use bonuses when they get the chance. The main one is to raise awareness of the company in question and to showcase the casino games you can play when you visit its platforms.

They also act as a great way of hooking your attention and promising to deliver a great start to your experience when you start to gamble online with this particular website or app.

Virtually all welcome offers are designed to enable you to try out an operator without having to invest too much of your own money. Whether it's a boost to your deposit or the chance to get your first day losses refunded, Illinois online casinos will want you to feel welcome and tempted to stay.

Bonuses for existing customers are designed to deepen your loyalty and ensure you aren't tempted to do your Illinois online gambling anywhere else, which is why ongoing promos such as bonus spins, free-to-enter prize contests, and reload bonuses are regularly available.

How to Calculate the Value of a Casino Bonus

It can be useful to work out precisely how much value you are getting from any welcome bonuses offered by online casinos in Illinois. It's also useful to be able to work out how much you have to wager on a daily basis to get the most out of such promotions.

Let's look at a couple of examples of offers currently available from operators likely to launch online casinos in Illinois when they get the chance. In each instance, we'll assume you want to release the maximum available in bonus funds from a deposit bonus match - and that you are an online slots fan.

As with all offers, always check the fine print. In this case, it's useful to know that the welcome offer at the Caesars Palace online casino stipulates that you must play through the amount of both your deposit and your bonus.

There will surely be plenty of interest in playing real-money casino games at mobile casinos in Illinois, an interest that will be encouraged by promotions that offer a boost to your bankroll or the chance to enjoy free spins.
