Best Online Casino Free Spins Bonuses in the US October 2026

DraftKings Casino has evolved the traditional Free Spins promotions to give you Flex Spins. The "Flex" part comes from the fact that you can use the bonus to play most of the 1,000+ slots, rather than a select one or two.

When you create a new account at DraftKings in MI, PA, NJ, WV, or CT, you can get 1,000 Flex Spins when you deposit and wager just $5. The Flex Spins will be credited to your account in increments of 50 across your first 20 days. You can check the exact details in the banner below.

You're probably aware of the Hard Rock brand, given that its cafes are a US institution that has gone global over the past five decades. But did you know that Hard Rock Bet now also has a casino that's available to players aged 21 + in Michigan and New Jersey?
