5. Deposit funds

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

Illinois sportsbook promos FAQ

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

Yes, there is no limit to the number of IL sportsbook promos bettors can claim. The only requirement is that itโ€™s your first time registering for the sportsbook. One piece of advice we can offer is that itโ€™s a good idea to register for only one or two at a time. The promos expire as early as one week, and you donโ€™t want to feel rushed into hasty wagers.

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 sportsbookโ€™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 โ€œhidden feesโ€ 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. Itโ€™s smart to be ready to wager when you register for an app. Secondly, itโ€™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, itโ€™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.
