What are free spins bonuses?
Free spins are one of the most straightforward bonuses you'll find at online casinos. They give you a set number of spins on eligible slot games without requiring you to use your own money, and any winnings you pick up are either paid out as cash or added to your bonus balance depending on the terms. Most free spins offers at licensed US casinos come with low or no wagering requirements, which means you can often withdraw your winnings without having to jump through too many hoops.
You'll find free spins offered in several different ways, most commonly as part of a welcome package when you make your first deposit. Some casinos issue them all at once, while others drip them out in daily batches over a set number of days. Either way, they're one of the best ways to explore a casino's slot library without committing more of your own funds, and when the terms are favorable they can add real value to your first experience at a new site.
Best real money free spins bonuses
Free spins are one of the most popular types of casino bonus, and for good reason. They give you real playtime on slot games without putting more of your own money at risk, and any winnings you pick up along the way are yours to keep.
All four casinos below include free spins as part of their welcome package, and each one takes a slightly different approach to how they work. Here's a quick breakdown to help you compare.
| Casino | Free spins | Min. deposit to claim | Wagering on spins | Free Spin value |
|---|---|---|---|---|
| DraftKings | 1,500 Flex Spins (50 per day for 30 days) | $5 | No wagering on free spins | $0.20 per spin |

| FanDuel | 500 spins (50 per day for 10 days) | $10 | No wagering on free spins | $0.20 per spin |

DraftKings Casino - 1,500 Free Spins Bonus
DraftKings is one of the most recognizable names in US online gambling, and its casino lives up to the brand's reputation. For players interested in free spins, it's hard to beat the welcome offer right now. New players get 1,500 Flex Spins just by wagering $5, issued as 50 spins per day over 30 days.
What makes this offer stand out is the flexibility. Unlike most free spins bonuses that lock you into a single game, DraftKings lets you choose from over 100 eligible slot titles each day, so you're not stuck spinning a game you don't enjoy. There's also no wagering requirement on the winnings, meaning anything you pick up from the spins is withdrawable as cash straight away.
Beyond the free spins, DraftKings offers a strong overall casino experience. The game library runs to 1,400+ titles including a solid collection of exclusive games, many of which are tied into a site-wide progressive jackpot pool. Live dealer tables, slots, table games, and video poker are all well represented.
The Dynasty Rewards loyalty program earns you Crowns on every bet, redeemable for DK Dollars or exclusive perks, which gives you a reason to keep coming back after the welcome offer is done. The mobile app is highly rated on both iOS and Android and connects seamlessly with DraftKings Sportsbook and DFS under one account if you use those products too.
DraftKings Casino is available in Michigan, New Jersey, Pennsylvania, and West Virginia. No promo code is needed to claim the welcome offer, just a $5 wager to get things started.

bet365 Casino
bet365 is one of the most established casino brands in the world, and its US product brings that global experience to players in New Jersey and Pennsylvania. The free spins welcome offer is one of the cleanest available right now.
New players get up to 1,000 spins with a $10 deposit, revealed over 10 days by spinning a prize wheel that awards 5, 10, or 20 spins each time. There's no wagering requirement on any winnings from the spins, so whatever you pick up goes straight into your withdrawable balance. The spins are locked to a small selection of exclusive bet365 titles, but the wager-free nature of the offer more than makes up for that limitation.
Alongside the spins, new players also get a 100% deposit match up to $1,000, which is one of the larger deposit match offers available at a US online casino. The wagering requirement on the match bonus is 30x in New Jersey and 25x in Pennsylvania, which is on the higher end, but the deposit match gives you a serious amount of extra funds to explore the library with.
bet365's game selection runs to 1,500+ titles including a strong live dealer section powered by Playtech with 50+ tables, and a growing collection of exclusive slots. Withdrawals are fast, typically processed within a few hours for PayPal and debit card, and customer support is responsive. The one notable gap is the absence of a loyalty or VIP program, which most competing casinos do offer.
| 🎰 Free spins offer | Up to 1,000 spins (revealed over 10 days) |
| 💵 Min. deposit to claim | $10 |
| 📋 Wagering on spins | No wagering |
| 💲 Spin value | $0.20 per spin |

| ⚡ Withdrawal speed | Within a few hours via PayPal |

FanDuel Casino
FanDuel is already one of the most trusted names in US sports betting and daily fantasy, and its casino is just as well put together. The welcome offer gives new players 500 bonus spins and $40 in casino credits with a $10 deposit, and the terms are about as clean as it gets.
The spins carry no wagering requirement whatsoever, meaning any winnings from them are immediately withdrawable. They're issued at 50 per day over 10 days, giving you a steady stream of play rather than a one-time drop. The $40 casino credit comes with a low 1x wagering requirement, which is well below the industry standard and easy to clear without any real effort.
FanDuel's casino library sits at 850+ games, with a particularly strong selection of exclusive slot titles alongside live dealer tables powered by Evolution Gaming. The platform is clean and easy to navigate, which makes it a solid choice for players who are newer to online casino gaming.
Daily promotions like the Reward Machine give existing players a reason to log in regularly even after the welcome offer runs out. FanDuel Casino is available in Michigan, New Jersey, Pennsylvania, and West Virginia, and the app is one of the highest rated in the space with a 4.9 star iOS rating.
| 🎰 Free spins offer | 500 bonus spins (50 per day for 10 days) |
| 💵 Min. deposit to claim | $10 |
| 📋 Wagering on spins | No wagering |

Playstar Casino
Playstar is a newer name in the US market but one that's built a strong reputation quickly, particularly in New Jersey. The free spins welcome offer is generous at up to 500 spins, though the way it's structured is different from the other casinos on this list. Rather than delivering all the spins upfront, they're spread across your first three deposits, with 100 spins on the first and 200 on each of the second and third.
You need to deposit and wager at least $20 each time to unlock each batch. The spins carry no wagering requirement, so winnings are yours to withdraw straight away. Each spin is valued at $0.10, slightly lower than the $0.20 standard elsewhere, but the sheer volume and the wager-free terms still make it a worthwhile offer.
Playstar pairs the spins with a 100% deposit match up to $500 on your first deposit, which comes with a 30x wagering requirement. The game library covers 1,200+ titles including 1,100+ slots from providers like NetEnt, IGT, and Light & Wonder, a strong live dealer section via Evolution Gaming, and exclusive Star Jackpots titles.
The PlayStar Club VIP program is one of the better loyalty schemes at a US online casino, offering weekly cashback, reload bonuses, and gift cards for consistent players. One thing to note is that the minimum age to claim the welcome bonus at Playstar is 25, higher than the standard 21 at most other US casinos, and the casino is currently only available in New Jersey.
| 🎰 Free spins offer | Up to 500 spins (split across first 3 deposits) |
| 💵 Min. deposit to claim | $20 per deposit |
| 📋 Wagering on spins | No wagering |
| 💲 Spin value | $0.10 per spin |

How to claim free spins at an online casino
Claiming a free spins bonus is straightforward at any of our recommended casinos. The process is almost identical across all of them, and the whole thing takes just a few minutes. Here's how to do it.
- Use our link to visit the casino: Click one of the links or banners on this page to visit your chosen casino and make sure the welcome offer is automatically applied.
- Create your account: Fill in the registration form with your basic personal details, or sign up instantly using an existing Google or Facebook account where available.
- Verify your identity: Confirm your email address and phone number, and upload a copy of your ID if prompted, as this is required before any bonus can be activated.
- Make your qualifying deposit: Head to the cashier and deposit at least the minimum required amount using a standard payment method like a debit card or PayPal.
- Opt in to the welcome offer if required: If your spins haven't appeared automatically, check the promotions tab in your account and opt in from there.
- Claim your spins and start playing: Your free spins will be credited to your account either immediately or in daily batches, ready to use on eligible slot games.
Free spins at sweepstakes casinos (available in restricted states)
If you're in a state where real money online casinos aren't legal yet, sweepstakes casinos are a great alternative. They don't offer free spins in the traditional sense, but free coins work in a very similar way. You receive Gold Coins and Sweeps Coins just for signing up, which you can use to spin slot games without spending anything.
The main difference is flexibility. Instead of being locked into a fixed number of spins on a specific game, you get a bundle of coins you can use freely across the entire game library. With Sweeps Coins, you also have the chance to redeem your winnings for real prizes, making it a genuinely worthwhile alternative for players in restricted states.
| Casino | Our Rating | Welcome bonus | Number of games |
|---|---|---|---|
| CrownCoins | 4.85/5 | 200% more coins on first purchase: 1.5M CC + 75 SC | 500+ |
| Stake.us | 4.75/5 | 25 SC + 25,000 GC signup bonus | 2,200+ |
| LoneStar Casino | 4.75/5 | Up to 500,000 GC + 105 SC + 1,000 VIP points | 500+ |
| SpinQuest | 4.65/5 | 200% extra: 300,000 GC + 30 SC | 1,000+ |
| McLuck | 4.65/5 | Spin up to 500 SC + 120,000 GC + 60 extra SC | 1,300+ |

Types of free spins at online casinos
Not all free spins are the same. The way you earn them, the terms attached, and when they land in your account can vary quite a bit depending on the type of offer. Here's a breakdown of the most common ways you'll come across free spins at US online casinos.
💳 Deposit free spins
These are the most common type of free spins bonus and are usually part of a casino's welcome package. You make a qualifying deposit and the spins are credited to your account either immediately or in daily batches. The deposit amount required is typically low, starting at $5 to $20, and the spins often carry no wagering requirement on winnings at top US casinos.
🎁 No deposit free spins
No deposit free spins are credited to your account just for signing up, with no financial commitment required. They're less common at US real money casinos than at international sites, but they do exist and are worth seeking out since they let you try a casino completely risk-free. The number of spins is usually smaller than a deposit offer, but the fact that you don't need to spend anything to claim them makes them genuinely valuable.
👑 VIP and loyalty program free spins
Many online casinos reward regular players with free spins as part of their loyalty or VIP program. These are typically awarded when you reach a new tier, hit a certain number of points, or as a weekly or monthly perk for active players. The higher your VIP level, the more spins you tend to receive, and they often come with better terms than standard promotional spins.
🎰 In-game free spins
In-game free spins are triggered by landing specific symbols, usually scatter symbols, during regular slot play. They're built into the game itself rather than offered as a bonus by the casino, and are one of the most exciting features in modern slots. Many in-game free spin rounds also include multipliers, expanding wilds, or other special mechanics that can significantly boost your payout.
🏆 Tournament and leaderboard free spins
Some casinos award free spins as prizes in slot tournaments or leaderboard competitions. You compete against other players by accumulating points or wins on eligible games over a set period, and the top finishers share a prize pool that often includes free spins alongside cash rewards. These are a great way to earn extra spins as an existing player without making an additional deposit.
📧 Free spins via email or social media
Casinos regularly send free spins offers to existing players through email promotions or social media giveaways. These tend to be time-sensitive and tied to specific games or events, so it's worth following your casino on social media and keeping an eye on your inbox to make sure you don't miss them. Opting in to marketing emails during registration is usually how you stay eligible for these offers.
🔄 Reload free spins
Reload free spins are offered to existing players alongside a reload deposit bonus, rewarding you for making a subsequent deposit after your initial one. They work the same way as welcome deposit spins but are designed to keep regular players engaged over time. These are usually found in the promotions tab and may require you to opt in before making the qualifying deposit.
Terms and conditions of free spins offers
Free spins bonuses always come with terms attached, and it pays to know what they mean before you start playing. None of them are complicated once you understand the basics. Here's a breakdown of the most important ones to look out for.
| Term | What it means | Typical value |
|---|---|---|
| Wagering requirement | The number of times you need to play through your winnings before you can withdraw them. Most free spins offers at US casinos have low or no wagering requirements, which is much better than the industry norm. | 0x to 1x (at top US casinos) |
| Minimum deposit | The amount you need to deposit to trigger the free spins offer. Most casinos set this low to make the bonus accessible to all players. | $5 to $20 |
| Spin value | The fixed monetary value assigned to each free spin. This determines how much each spin is worth and affects the total potential value of the offer. | $0.10 to $0.20 per spin |
| Eligible games | Free spins can only be used on specific games chosen by the casino. Always check which titles are included before you start, as the selection can be limited. | 1 to 100+ eligible slots |
| Expiry period | The window of time you have to use your free spins before they disappear from your account. Daily spin batches often have a shorter expiry than the overall offer. | 7 to 30 days |
| Maximum withdrawal | Some casinos cap how much you can withdraw from free spin winnings. Not all US casinos apply this restriction, but it's worth checking before you play. | $50 to $500 (where applicable) |
| Opt-in requirement | Some bonuses require you to manually activate the offer through the promotions tab before or after depositing, otherwise the spins won't be credited. | Required at select casinos |
Free spins vs free cash
Free spins and free cash are both popular types of casino bonus, but they work quite differently. Free spins are credited as a set number of plays on eligible slot games, each with a fixed value per spin. They're straightforward to use but limited to slots, and the total value is capped by how many spins you receive and what each one is worth.
Free cash, on the other hand, is credited as bonus funds that can typically be used across a wider range of games including table games and live dealer, giving you more flexibility in how you play.
The key difference comes down to control and versatility. Free spins are great for slot players who want extended playtime with low or no wagering attached, while free cash tends to offer more freedom but often comes with higher wagering requirements before you can withdraw any winnings. Neither is strictly better than the other. It really depends on what type of games you enjoy and how much you value flexibility versus simplicity.
| Free spins | Free cash | |
|---|---|---|
| What you get | A set number of spins on eligible slot games | Bonus funds credited to your account |
| Eligible games | Slots only | Slots, table games, live dealer (varies by casino) |
| Wagering requirements | Often low or none at top US casinos | Typically higher, usually 10x to 30x |
| Spin/bet value | Fixed, usually $0.10 to $0.20 per spin | Flexible, you choose your stake |
| Total potential value | Capped by number of spins and spin value | Can be higher depending on deposit match percentage |
| Best for | Slot players who want low-risk playtime | Players who want flexibility across game types |
| Ease of withdrawal | Often easier due to low or no wagering | Can take longer due to higher wagering requirements |
What does it take to trust a casino with free spins?
When you go to a casino with free spins, you’ll want to make sure that you’re being kept safe. After all, these are free spins real money casino sites, and so you won’t want anybody running off with your deposits. So here are the top five things that we look for before we recommend that you visit any online casino site to get their free spins:
- Clear terms and conditions: All free spins promotions will be accompanied by some lengthy terms and conditions. These detail what you have to do to get your free spins, as well as how you are allowed to use the free spins. This information should be easy to find and simple to understand. If you find a free spins bonus without any small print, it’s probably trying to hide something.
- Licensing and regulation: Only get free spins promotions from those fully licensed and regulated online casinos. If a casino site lacks licensing, then there’s nothing holding it to honour the promotion or pay you any winnings that you make with the deal. The good news is that every online casino featured on our resource is fully licensed and regulated.
- Online security technologies: You’ll always have to sign up to an online casino site in order to access their free spins promotions. As a result, you will want reassurance that the casino is capable of handling your personal details. We’ll recommend only using those online casinos that feature SSL-level encryption to make sure that all of your data and communication stays in safe hands.
- Helpful customer support: Most free spins promotions work fine, but there might come a time where you need help in activating or using the special offer. This is where you’d want to get assistance from the online casino’s customer service team. As a result you’d be able to get help in using your free spins, or anything else to do with the casino site such as making deposits, withdrawals and so on.
- Reliable payment methods: You shouldn’t have to make a payment in order to get a true ‘free spins’ deal, but you will still need to know how you’ll be making your real money withdrawals. This is why all of our featured online casinos let you make deposits and withdrawals with the most trusted payment providers.

Tips to make the most of your free spins
Free spins are a great way to get extra playtime at an online casino, but a few smart habits can help you get more value out of them. Here are some practical tips worth keeping in mind before you start spinning.
📅 Claim your daily spins consistently
Most free spins offers at US casinos are issued in daily batches, typically 50 spins per day over 10 to 30 days. Each batch expires within 24 hours of being credited, so missing a day means losing those spins permanently. Set a daily reminder if you need to, as this is the easiest way to make sure you claim the full offer.
🎮 Check eligible games before you start
Free spins are locked to specific games, and at some casinos your first spin from a daily batch locks all remaining spins to that title for the day. Take a minute to browse the eligible games list before committing, so you're playing something you actually enjoy rather than getting stuck on a game that doesn't suit you.
📋 Understand the wagering requirements before you withdraw
Even if the spins themselves are wager-free, any accompanying casino credits or deposit match bonuses may still carry a wagering requirement before withdrawal. Check which part of your bonus has conditions attached and clear those requirements before requesting a payout to avoid any surprises.
💰 Start with free spins before using your own funds
Use your free spins first before dipping into your deposited balance. This gives you a chance to get familiar with the games, find titles you enjoy, and potentially build your balance before you start playing with your own money.
⏰ Keep an eye on expiry dates
Free spins and bonus funds have expiry dates, and unused spins are simply removed from your account once the deadline passes. Check the terms when you sign up so you know exactly how long you have, and plan your sessions accordingly to make sure nothing goes to waste.
🔍 Compare spin values before choosing a casino
Not all free spins are equal. A 500 spin offer at $0.10 per spin is worth $50 in total, while 500 spins at $0.20 per spin is worth $100. Always check the spin value before deciding which welcome offer gives you the most actual value for your deposit.

The kinds of free spins our experts pick up
It’s important to remember that not all free spins bonuses are created equal. After all, there are free spins deals that are great value for money, and others which are a little more complicated. So here is a quick overview of the key things that our experts look at before they get any free spins promotion.
Are free spins really free?
While these promotions will be advertised as ‘free spins’, many of these offers can only be claimed by you putting down either a qualifying deposit or a qualifying bet. As a result, it’s best to think of such deals as being ‘bonus spins’ or ‘extra spins’ rather than them giving you spins for free. So be sure to read through the small print of each free spin promotion first so that you can see how it really works.
What games can you use the free spins for?
There’s no point in picking up some free spins unless you know that you can use them on a decent slot game. This is why it’s always good to do some research to see whether the slot game has a favourable volatility and what its return to player percentage is. We would also recommend checking out which gaming studio developed the slot game so that you get a good idea as to how good the gameplay is and so on.
What are the wagering conditions?
It’s pretty rare to find free spins that let you withdraw any winnings you make without fulfilling any wagering requirements first. As such, we can see that wagering conditions are a hugely important part of any free spins deal. After all, if you can only make a withdrawal after you have wagered the value of your winnings dozens of times, it might make the special offer a lot less attractive. So be sure to see what the wagering conditions are before you rush to claim those free spins.
How long do the free spins last?
We should also note the fact that many free spins bonuses can last for a very short amount of time. Some free spins bonuses last for a handful of days while other bonus spins promotions may last for just 24 hours. Don’t forget that the wagering conditions of these free spins deals may also have to be fulfilled within these time limits. So be sure to only claim these casino promotions when you know that you have enough time to put them to good use.
Conclusion - Get started with the best online casino free spins
