The best online casino bonus is not the one with the biggest number. It is the one you can realistically clear, on games you actually want to play, in the state where you live. This guide compares the current welcome offers at six licensed US online casinos, explains how to judge any bonus in under a minute, and shows the math behind wagering requirements with real examples.
Casino Funk does not run games or take bets. Offers below were checked in October 2026. Bonus terms change often and can differ by state, so always confirm the current terms on the operator’s site before you opt in.
Key takeaways
- Low wagering beats a big headline: a 1x bonus is usually worth more than a large match with 15x to 30x playthrough.
- Most US welcome offers are bonus spins, deposit matches or lossback credits.
- Table games and video poker often count far less toward wagering than slots.
- Offers differ by state and are only available to players 21+ located in a legal online casino state.
- Never deposit more than you planned just to unlock a bigger bonus.

How to judge any casino bonus in 60 seconds
- Find the wagering requirement. This is how many times you must bet the bonus (and sometimes the deposit) before you can withdraw. Lower is better; 1x is excellent, 15x is average, 30x or more is heavy.
- Check game contribution. Slots usually count 100%. Blackjack, roulette, baccarat and video poker may count 10% to 20%, or be excluded.
- Check the time limit. Bonuses often expire in 7 to 30 days. Spins may be released in daily batches that disappear if unused.
- Look for a maximum bet. Some bonuses cap your stake while wagering is active.
- Check spin value and eligible games. 1,000 spins at $0.10 each is $100 of play, often on one specific slot.
- Confirm your state. The same brand may run different offers in New Jersey, Pennsylvania, Michigan and West Virginia.
Wagering requirements: the math with real examples
Wagering is easiest to understand with numbers. Assume a slot with a 96% return to player (RTP), which means a house edge of about 4%.
| Bonus | Wagering | Total you must bet | Expected cost of that play (4% edge) | Expected value left |
|---|---|---|---|---|
| $100 bonus funds | 1x | $100 | about $4 | about $96 |
| $100 bonus funds | 15x | $1,500 | about $60 | about $40 |
| $100 bonus funds | 30x | $3,000 | about $120 | below zero on average |
| $100 lossback credit | 1x | $100 | about $4 | about $96, but only if you lost first |
The same “$100 bonus” can be worth almost its face value or close to nothing, depending only on the playthrough. That is why low-wagering spins from DraftKings, FanDuel and Fanatics often beat larger deposit matches. Deposit matches still make sense for players who planned to wager a lot anyway, but they should be judged on the wagering, not the headline amount.
For a deeper explanation, read our guide to casino wagering requirements.
Types of online casino bonuses in the US
- Bonus spins: free spins on selected slots, usually with a fixed value per spin. Winnings may be paid as cash or as bonus funds with wagering.
- Deposit match: the casino matches a percentage of your first deposit, such as 100% up to $1,000, in bonus funds with a playthrough requirement.
- Lossback (or “second chance”): if you lose during a set period, you receive some or all of the loss back as bonus credit, usually with low wagering.
- No-deposit bonus: a small credit for signing up. These are less common and usually small.
- Reload and loyalty offers: ongoing promotions and reward points for existing players. Programs like Caesars Rewards and BetMGM Rewards can link to hotel and dining benefits.
Bonuses and table games
If you mainly play blackjack, roulette, baccarat or video poker, read the game contribution table before you accept any offer. A bonus with 15x wagering at 100% slot contribution can become effectively 75x or 150x if your preferred game counts only 20% or 10%. In some cases, table game players are better off declining a deposit match and playing with their own money, keeping full control over withdrawals.
Which bonus suits which player?
| Player type | Usually the better fit | Why |
|---|---|---|
| New or casual player | Low-wagering bonus spins (DraftKings, FanDuel, Fanatics) | Small deposit, 1x playthrough, easy to understand |
| High-volume slot player | Deposit match (BetMGM, bet365, Caesars) | Larger bonus pool, if you were planning to wager the amount anyway |
| Table game player | Lossback or no bonus | Table games often count little toward wagering |
| Rewards-focused player | Casinos tied to resorts (BetMGM, Caesars) | Online play can earn points usable in person |
Where these bonuses are available
Real-money online casino bonuses are only available in states with licensed online casinos. Our state guides explain the rules, licensed apps and protections in each:
- Michigan online casinos
- New Jersey online casinos
- Pennsylvania online casinos
- West Virginia online casinos
- Connecticut, Delaware and Rhode Island also have legal online casinos, with fewer brands.
You must be 21+ and physically located in the state when you claim and use a bonus. Sweepstakes and offshore casinos that advertise huge bonuses are not licensed by state regulators and offer none of their protections.
How bonus spins really work
Bonus spins are the most common welcome offer in the US right now. Each spin has a fixed value, often $0.10 to $0.20, and is usually locked to one or a few named slots. Large spin packages are often released in daily batches over 10 to 20 days, and any batch you do not use in time expires. Winnings from spins are paid either as cash, which you can withdraw immediately, or as bonus funds that carry their own wagering. Before you claim, check the value per spin, the eligible games, how batches are released and how winnings are paid out.
Lossback offers explained
A lossback offer refunds some or all of your net losses over a set window, often the first 24 hours, as bonus credit. If you finish the window ahead, you get nothing back, but you keep your winnings. If you finish behind, you receive credit up to the stated limit, usually with low wagering. Lossback suits players who want to try a casino with real money and some protection on a bad first session. It does not suit players who would increase their bets just because they feel “covered”.
How to claim a casino bonus step by step
- Read the full bonus terms on the casino’s promotions page, not just the banner.
- Register and verify your account; most offers require a completed identity check.
- Opt in, or enter the promo code if one is required, before your first deposit.
- Make the qualifying deposit or wager using an eligible payment method.
- Track your progress in the casino’s bonus or rewards section.
- Withdraw only after the wagering is complete, so the bonus and its winnings are not cancelled.
Bonus terms glossary
- Wagering requirement (playthrough): how many times bonus funds must be bet before withdrawal.
- Game contribution (weighting): the percentage of each bet that counts toward wagering on a given game.
- Qualifying deposit: the minimum deposit that unlocks an offer.
- Maximum bet: the largest stake allowed while a bonus is active.
- Expiry: the deadline for using spins or completing wagering.
- Restricted games: games that cannot be played with bonus funds or do not count toward wagering.
- Site credit / casino credit: bonus funds that must be played before they turn into withdrawable cash.
Why the same casino offers different bonuses by state
Each state regulates online casinos separately, so promotions are approved and run state by state. Tax rates, advertising rules and competition all differ. Pennsylvania, for example, taxes online slot revenue at 54%, while New Jersey taxes online casino revenue at 19.75% and West Virginia at 15%. These differences can shape how generous an operator’s offers are in each market. A lossback cap can be lower in one state than another, and some promotions run in only a few states. Always open the promotions page while you are located in your own state, because that is the version of the offer that applies to you.
Common bonus mistakes to avoid
- Chasing the biggest number. A $1,000 match at 30x is harder to clear than most players expect.
- Depositing more than planned just to unlock the maximum match.
- Missing opt-in steps or promo codes, which can make you ineligible.
- Playing excluded games while wagering is active.
- Ignoring expiry dates on spins and bonus funds.
- Withdrawing too early, which can cancel an active bonus and its winnings.
- Taking a bonus you do not need. Declining an offer is always allowed.
Responsible use of casino bonuses
Bonuses are marketing tools designed to get you playing. Set a deposit limit before you claim anything, treat any bonus as extra entertainment rather than income, and never chase losses to meet a wagering requirement. Licensed US casinos must offer deposit, time and loss limits plus self-exclusion. If gambling stops being fun, call or text 1-800-GAMBLER, and see our responsible gambling guide.
Online casino bonuses FAQ
What is the best online casino bonus right now?
For most players, low-wagering offers such as bonus spins with 1x playthrough give the best real value. Players who wager heavily on slots may get more from a deposit match. Compare the terms in our reviews before choosing.
What does 1x wagering mean?
You must bet the bonus amount once before it can be withdrawn. For example, $50 in bonus funds at 1x requires $50 in wagers.
Can I claim welcome bonuses at more than one casino?
Yes. Each licensed casino offers its own welcome bonus, so you can claim one per casino where you open an account, subject to each operator’s terms.
Do bonus winnings count as taxable income?
Gambling winnings, including those from bonus play, are generally taxable. Keep records and check with a tax professional.
Can I use a casino bonus on blackjack?
Often only partly. Many US casinos count blackjack at a reduced rate toward wagering, and some exclude it. Check the game contribution table in the bonus terms.
