How do online casino bonuses work?

A casino bonus gives you extra credit or spins in exchange for conditions. The key condition is usually a wagering requirement, which sets how much you must bet before you can withdraw. Michigan requires offers to state their terms clearly, including expiry dates, eligible games and withdrawal limits.

On November 9, 2026, 7 of the 14 licensed casinos we track listed a welcome offer with 1x wagering or none: Fanatics Casino, Golden Nugget Casino, Bally Casino, FanDuel Casino, BetRivers Casino, DraftKings Casino and Hard Rock Casino. Our sign-up bonus comparison lists every offer with its wagering, minimum deposit and states.

What are the common types of casino bonus?

Most fall into a few groups. Terms vary by casino and by state.

  • Deposit match: the casino adds bonus credit based on what you deposit.
  • Free spins: spins on set slot games, often with a cap or conditions on winnings.
  • No-deposit bonus: a small credit that does not need a deposit, usually with conditions.
  • Loss-back: credit based on what you lose during a set period.

What must a casino bonus disclose?

Michigan gives the clearest list we have read. Offers must be in clear and unambiguous terms, and the terms must cover:

  • Start and expiry dates and times.
  • Who is eligible, and any participation limits.
  • Withdrawal restrictions.
  • Wagering requirements and limits by game type.
  • The order in which funds are used.
  • Which games count, and how an offer can be cancelled.

Can you cancel a casino bonus?

In Michigan, yes. Operators must give you a clear and conspicuous way to cancel offers that use restricted credits, and remaining unrestricted funds are returned according to the terms. Check the terms first, because cancelling can cost you bonus money and any winnings tied to it.

Can a casino limit what you win from a bonus?

Michigan bars operators from limiting winnings earned during an offer once you have met its terms. Before that point the terms decide, so read any cap. New Jersey separately bars operators from placing wagering requirements on withdrawals of your own deposited funds.

What are the rules in your state?

Each state sets its own online casino rules. Pick a state to see its status, its regulator and the date we last checked it.
