Our full breakdown of this promo — terms, value, and verdict.
Bonus bets sound simple: you get credit, you place a bet, you keep the winnings. The fine print is where that simplicity ends. Illinois is a fully regulated market under the Illinois Gaming Board, but the IGB does not standardize promo terms across operators. That means the rules vary, and a missed detail can cost you the entire credit.

What does "single-wager requirement" actually mean?
Many promos require the bonus bet to be placed as a single wager — not a parlay — or on odds of −200 or longer. If you try to use a bonus bet on a 4-leg parlay and the terms forbid it, the bet is voided and the credit is forfeited. That rule alone catches a lot of bettors off guard. Read the odds restriction first. A line of −200 or longer means you must bet a market where you risk $200 to win $100, or a market with a longer implied probability. Tighter favorites are often excluded.
How long do bonus bets stay in my account?
Expiry windows on bonus bets commonly range from 7 to 30 days. Illinois-specific expiry terms were not confirmed at time of writing, so verify the exact window inside each operator's terms page the moment you opt in. A 7-day window is tight if you're waiting on a specific game. Set a calendar reminder the day you claim the credit.
Can I withdraw a bonus bet?
No. Bonus bets issued by US sportsbooks are non-withdrawable. Only the winnings generated from a bonus bet can be cashed out — the original credit stake is never returned. That distinction matters for budgeting. If you place a $150 bonus bet at +100 and win, you collect roughly $150 in cash profit, not $300.

What is the rollover and does Illinois enforce a higher one?
Standard playthrough on bonus bets at US books is typically 1× to 2× the bonus amount. A 1× rollover means a $100 bonus bet must be wagered once before winnings unlock. Illinois-specific rollover terms were not confirmed; always check each book's current T&C. A low rollover is meaningfully better — do not skip that number.

Is a bonus bet actually worth more than a deposit match?
It depends on the rollover, the odds restriction, and your betting style. A deposit match with a 1× rollover at open odds can be more flexible than a bonus bet locked to a single straight wager at −200 or longer. Neither guarantees a profit. For a side-by-side analysis, read Bonus Bet vs Deposit Match: Which Illinois Promo Is Worth More?. Illinois promos are only available to bettors physically located in Illinois and aged 21 or older at time of wagering.
What happens if I use an expired promo code?
The bonus will not apply. Many welcome codes are time-limited or tied to a specific event. Using an expired code at signup means you forfeit the offer entirely — the operator will not apply it retroactively. Enter the code before you deposit, not after.
