Have you tried ESPN BET? They’re relatively new (launched November 2023) but they’re already in 18 states. Their welcome bonus is pretty generous – up to $600 in bonuses. They match your deposit at 200% up to $500, plus you get $100 in bonus bets when you place your first $10+ bet. The app ratings are solid too – 4.8 on iOS and 4.2 on Android.
