How we rate & rank Illinois sportsbook bonuses
Our team aims to provide you with unbiased, objective promo reviews, so you understand their strengths and weaknesses.
We always use a set of eight criteria to evaluate each promo offer, which means you can compare them easily and effectively:
Type of promo: We prioritize promotions that appeal broadly, enhancing user engagement with offers suited to different betting styles.
Promo value: We assess the value for money, ensuring bettors receive substantial rewards and maximum returns from participating in promotions.
Customer support: We test the effectiveness of customer support, focusing on resolving promo-related issues quickly and building user trust.
Promo expiry date: We evaluate the timeframe allowed for using promos, ensuring sports bettors have ample time to make the most of their bonuses.
Wager T&Cs: We review wagering terms and conditions to ensure they are fair and transparent, allowing bettors to fully enjoy their rewards.
Sportsbook experience: We assess the overall online sportsbook experience, ensuring users can easily navigate and claim promotions across both web and sports betting app platforms.
Minimum bet deposit: We verify the accessibility of promos by checking for low minimum bet deposits, making them available to more bettors.
Betting site security: We ensure top-tier security measures are in place, protecting bettors’ data and finances when engaging with promotions.
We download each US betting site and interact with the promo offers, using our own money to test the quality.
If we do not recommend the promo to our friends and family, we will not recommend it to you!

How do I choose a top Illinois sportsbook bonus?
Bonus value: The overall value of the bonus is a major factor. High-value bonuses, like BetMGM's $1,500 offer or Caesars' $1,000 bet insurance, provide a safety net for your first wager, especially if you're planning on placing larger bets. These promos are ideal if you're looking to maximize your potential winnings or minimize your losses on a big first bet.
Wager requirements: Pay close attention to the minimum deposit and qualifying wager requirements. FanDuel only requires a $5 wager to access its $150 bonus, while BetMGM requires a minimum deposit of $10 and a qualifying bet. Ensure you’re comfortable with the initial deposit amounts and the required bets, especially if you're working with a smaller budget.
Bonus flexibility: How you can use the bonus matters greatly. Promos like FanDuel's $150 in bonus bets allow you to split them up across multiple wagers, providing flexibility to place smaller bets. In contrast, other offers like BetMGM's bonus are split into larger increments, which may limit flexibility for those who prefer placing smaller or more frequent bets.
Expiration period: Every promo comes with an expiration period, and some are more generous than others. If you don’t plan on betting immediately or frequently, choose a promo with a longer expiration period to give yourself ample time to use the bonus.
Terms for winning or losing: Some promos only pay out if your first bet loses, like BetMGM’s and Caesars’ second-chance bets. Others, such as FanDuel's and DraftKings' offers, allow you to collect bonus bets regardless of whether your first wager wins or loses. This is important for bettors who prefer guaranteed bonuses instead of relying on the outcome of a bet.
Mobile app requirement: Many Illinois promos require the use of a sportsbook's mobile app to claim the bonus, such as FanDuel, which mandates app usage to unlock the $150 bonus. If you're someone who prefers desktop betting, ensure you're comfortable with this requirement or choose a promo that allows for flexibility across devices.
Minimum odds and bet type restrictions: Consider any restrictions tied to the odds of qualifying bets or bet types. Ensure that the bets you typically place align with these restrictions to avoid missing out on the bonus.

How to gamble responsibly on sports betting sites
Before we end this article, we need to caution you to always bet and play responsibly with Illinois sports betting sites.
To ensure you’re being cautious, these platforms implement various responsible gambling practices that will help you keep your betting habits in check and prevent unhealthy behaviors.
Limits: Online sportsbooks allow you to set betting limits, i.e. limit how much you can bet in a day, a week, or a month.
Cashouts: You can withdraw your winnings quite easily from any sports betting site. This prevents you from spending all of your winnings. There’s also the option for early cashout, so you can still get paid if the bet is starting to go sideways.
Help & resources: Online betting sites provide access to resources for problem gamblers and point them to organizations that can help with gambling addiction.
To help with sports betting, we created a 'how to bet on sports' guide, that helps new bettors understand the industry better, to play safer and more securely.
