Casino bonuses are scored with the Bonus Power Index, our own weighted system for measuring what an offer is worth in practice. The score is driven by four things: the real value of the bonus once wagering is accounted for, how achievable that playthrough actually is, whether the terms are fair on caps, expiration and eligible games, and how reliable the platform is at paying out. Real-money and sweepstakes offers run on separately weighted versions of the index, because a coin package and a deposit match are not comparable on the same scale.
Every offer is verified against the operator’s published terms before it is published, and re-checked on a schedule so the values on this page stay current.
Bonus.com may earn commission through affiliate partnerships. Placement in our rankings is determined by the score, not by any commercial relationship. Read the full methodology behind how we score casino bonuses.
Casino bonuses fall into six main types, and the right one depends less on the headline number than on how you play.
The casino welcome bonus is the largest offer most players will ever see from a single site, usually a deposit match, bonus spins or a loss-back on your first session. One per account, and it is the only chance you get at that value. The trade-off is that headline size and wagering usually rise together.

A no-deposit bonus gives you a small amount of bonus funds or spins for registering, with no money down. It suits anyone who wants to test a platform before committing a deposit. The amounts are small and the wagering and cashout caps are typically the strictest of any bonus type.

Free spins credit a set number of plays on specific slots, sometimes at a fixed low stake. They are the easiest bonus to use because there is nothing to work out before you play. The catch is that they are tied to chosen titles, and winnings often carry their own playthrough.

A casino deposit bonus matches a percentage of what you put in, commonly 100% up to a stated cap. It delivers the most bonus funds of any type and suits players who were going to deposit anyway. You have to fund the account first, and the match almost always carries the wagering.

These unlock at $5 or $10 rather than the $20 or more that larger offers require. They are the practical choice on a small bankroll, since the qualifying deposit is the real barrier for most players, not the bonus terms. The ceiling on what you can earn is lower to match.

A no-wagering bonus pays winnings as cash with no playthrough attached, so anything you win is withdrawable immediately. It is the cleanest structure available and the easiest to value accurately. Expect smaller amounts, tighter caps and fewer eligible games in return.

Every casino bonus comes down to three things: what you actually receive, what you have to do before you can withdraw it, and how long you have to do it.
A casino bonus gives you one of three things: matched funds tied to a deposit, a set number of spins on chosen games, or a small credit for signing up. None of it is cash. Bonus funds sit in a separate balance, they cannot be withdrawn on arrival, and they usually cannot be moved between games freely. What decides whether a bonus is worth claiming is the set of conditions attached to converting that balance into money you can take out.
Wagering requirements set how much you have to bet before bonus funds become withdrawable. A $100 bonus at 15x means $1,500 of wagering. Check whether the multiplier applies to the bonus alone or to the bonus plus your deposit, because the second version doubles the work. Game type matters too: slots typically count 100% toward the requirement, while table games and live dealer titles count far less or not at all. Our casino guides cover the mechanics in full.
Some bonuses need a code entered during registration or at the deposit step. Others apply automatically when you arrive through a tracked link, with no code involved at all. Missing a required code usually means forfeiting the offer, and support cannot always add it retroactively. Offers also expire, both as promotions and after activation, with most claimed bonuses running a 7 to 30 day window before unmet wagering voids the balance and anything won with it. If you are looking for a specific code, our casino promo codes directory lists current ones by brand.
The offers on this page are run by licensed US casinos, and the bonus is only one part of what you are signing up to. Payout speed, game library, app quality and how a site handles withdrawals all shape whether an offer is worth claiming in the first place. If you want to weigh those factors before picking an offer, compare real money online casinos first, then come back for the bonus.

Sweepstakes bonuses work on a different model. Instead of matching a deposit, sites hand out Gold Coins for play and Sweeps Coins that can be redeemed for prizes, with a free daily bonus for logging in and no purchase necessary at any point. Purchase offers are priced as coin packages rather than percentage matches, so value comes from the coins per dollar and the redemption terms, not from a wagering multiplier.

A casino bonus credits extra funds, spins or site credit when you register or make a qualifying deposit. That balance arrives with a wagering requirement, which is the total you must bet before it converts to withdrawable cash. Some offers activate automatically through a tracked link while others need a code at sign-up or deposit. Most run on a clock, commonly 7 to 30 days, and failing to complete the wagering in that window forfeits the bonus along with anything won from it.
Six types cover almost everything on the market: welcome and sign-up offers, no-deposit bonuses, free spins, deposit matches, low minimum deposit offers and no-wagering bonuses. Welcome offers are the largest and are limited to one per account. No-deposit and no-wagering bonuses are the smallest but carry the least risk, since one needs no money down and the other has no playthrough. Deposit matches deliver the most bonus funds but tie the value to how much you fund the account with.
Sometimes. Plenty of operators now apply the welcome offer automatically when you sign up through a tracked link, with no code field involved. Others still require one, either on the registration form or at the deposit step, and entering it late or not at all usually means the offer does not apply. Check which method a site uses before you register, because it is difficult to fix afterwards. Current codes by brand are listed on our casino promo codes page.
The Bonus Power Index is our proprietary scoring system for rating bonuses on what they deliver in practice rather than what they advertise. It weighs the value of the offer against its playthrough, the value of any spins included, the range of games the bonus can be used on, the popularity of the platform and its app store ratings. Real-money and sweepstakes offers are scored on separately weighted versions, so a coin package is never compared directly against a deposit match. The result is that a smaller offer with clean terms will often outrank a larger one with restrictive conditions.
We only feature platforms holding an active license from a recognized state regulator, and we verify those credentials directly with the issuing regulator where applicable.
A casino bonus is entertainment value, not a way to make money. Read the terms before you claim anything, because wagering requirements mean the balance is not yours to withdraw yet, and a large headline figure attached to harsh conditions is a worse offer than a small one with none. Never claim a new bonus to recover a loss from the last one, and never deposit more than you planned in order to reach a higher match tier. Bonuses are not suitable for everyone, and if the terms are pushing you toward playing longer or staking higher than you intended, the offer is not worth completing.
