How to choose a Illinois sportsbook

Compare more than the headline number. A big bonus can come with a rollover, minimum odds, or installment payouts. Our guide to reading wagering requirements shows what to check.
Shop lines. The same game can be priced differently across apps. Having accounts at more than one book lets you take the best number.
Match the app to how you bet. For example, BetMGM lists MGM Rewards Program, DraftKings lists DFS Integration, and FanDuel lists No Sweat First Bet.
Try the free tools. The bonus bet converter and odds converter help you see what an offer is worth before you claim it.
