What Are Online Casino Bonus Spins?
An online casino bonus spin is a spin that is issued to a customer that allows them to play a given slot game without having to spend any of their own money.
Bonus spins are a promotional offer provided by the top online casinos. They are often included in welcome offers for new users, but can also be included in offers for existing customers to help promote a new slot game or a seasonal set of slots.
These bonus spins are often for the lowest denomination available. Despite that, winnings from the bonus spins are often the user’s to keep and available for withdrawal right away.
Sometimes bonus spins at online casinos will be referred to as “Free Spins.” While that is true, as they are spins at no cost to the player, free spins is a term usually meant more for spins that occur in the midst of playing a slot. Most online slot games will have a free spins feature you can win in a given spin. Those are additional spins on top of the wagered spin you make. Bonus spins are given outside of the game to use, not within an actual spin. That being said, you can also win free spins while using a bonus spin.
Online Casino Bonus Spin Offers for New Users
The signature of any online casino is their new user bonus offer. These are the most exorbitant promotional packages an iGaming platform will offer, as it helps bring in customers and given them a chance to have a positive first experience.
While these offers will include things like deposit matches or loss back credits, most also include bonus spins. Here’s a look at the top US online casino promo offers that also include bonus spins.

Spins carry a $0.10 value and are valid on select slot games. Any winnings to come from them carry an additional 1x wagering requirement, meaning you need to play through the winnings one time before getting to keep them and withdraw them from your account.
Bonus Spin Promos for Existing Customers
Along with the bonus spins offers for new users, existing customers are open to regular bonus spin promotions.
These offers usually include far less bonus spins than the new user promotions, but are still a nice freebie to receive. What you can be looking for includes:
- New Game Promotions: Often an online casino will offer select bonus spins to use on a new slot game that is available. These can be anywhere from 5 to 50 spins in most cases.
- Daily Bonus Promotions: Some online casinos will feature a daily reward or daily bonus wheel that you can spin. Rewards featured in daily promotions will almost always have bonus spins as one of the potential prizes. These are usually limited to few spins for a particular game.
- Sportsbook Crossover Promotions: In some case, operators that have an online sportsbook and online casino will feature bonus spins for making a deposit at the sportsbook or making a particular online sportsbook wager. These spins can be a little more robust than daily offerings.
Playthrough Requirements for Bonus Spins
Playthrough requirements, also referred to as wagering requirements, are a requirement set by the online casino operator that customers must meet in order to have the ability to withdrawal their bonus funds.
When it comes to bonus spins, you don’t often find wagering requirements. They are very rare for new customer promotions. If they exist, they are usually limited to just 1x, which means any winnings from the bonus spins will need to be wagered one time before being unlocked to your account.
You may be more likely to see playthrough requirements attached to existing customer bonus spins. They may ask you to meet anywhere from a 1-5x playthrough requirement from winnings off your bonus spins. Again, that is not always the case and often times, bonus spins have no playthrough requirement.
Best Slots to Use Bonus Spins On
In some cases, you may not have much choice on what slot games you get to use them on. But, in other cases, you will have some flexibility.
If you do have some say in where you use your online casino free spins, it’s wise to consider using them on high RTP slots. RTP means Return To Player Percentage. It indicates the amount of money a slot game should return to the players over its lifetime.
The average RTP of an online slot is 96.0%. That means over the life of the slot, it will payback 96% of the wagers it receives. It should be noted that RTP is not a guarantee of success rate. You will not get back the RTP% in every session played.
Along with RTP, also consider the slot game’s volatility when using your bonus spins. Volatility describes the frequency and size of payouts for a given slot game. Volatility is measured as low (frequent payouts, but smaller in amount), high (less frequent payouts, but higher in amount), and medium (a balance of the two).
High RTP slots with high volatility tend to be part of the best payout casinos, as they can lead to some sizable jackpots.
Some of the slots with high payout potential include the Blood Suckers slots, Cash Eruption slots, 88 Fortunes slots, and Huff N’ Puff slots. Here’s a look at the top 10 RTP slots entering 2026.
Where Can I Use Online Casino Bonus Spins?
There are currently eight states that have legalized online casinos in the United States and seven that offer online casino games.
They are Connecticut, Delaware, Michigan, New Jersey, Pennsylvania, Rhode Island, and West Virginia. While the robust welcome offers are typically limited to the MI, NJ, PA, and WV markets, each state’s online casinos still do have promotions that will include bonus spins.
Each legal iGaming state goes through rigorous testing for its online casino platforms and games by the state’s regulatory organization to ensure fairness and legality. That also applies to any promotions offered. Any bonus spins issues will carry the same fairness and odds to win as a spin that you paid for with your own money.
Should you have an issue with how a game has performed, a bonus spin malfunction, or an issue with funds and prizes, you can contact that state’s regulation board to present your case.
The state regulators for the seven legal US online casino states are:
- Connecticut: Connecticut Department of Consumer Protection
- Delaware: Delaware State Lottery
- Michigan: Michigan Gaming Control Board
- New Jersey: NJ Division of Gaming Enforcement
- Pennsylvania: Pennsylvania Gaming Control Board
- Rhode Island: Rhode Island Lottery
- West Virginia: West Virginia Lottery Commission
Sweepstakes Casino Bonus Spins
Bonus spins are just limited to legal online casinos. You can also find them at the top sweepstakes casinos. Sweepstakes casinos are free-to-play casino games that use Gold Coins and Sweeps Coins instead of real money. Users receive welcome packages of Gold and Sweeps Coins to play, then have the option to purchase more if they choose. Some sweeps casinos will include bonus spins as part of their welcome packages or offers, while others provide bonus spin offers for returning customers as well.
Legal Online Casino Bonus Spins vs. Offshore Casino Bonus Spins
Online casino bonus spins are nice to receive, but it’s important to know that you are using them at a legal US online casino.
We have included many of the legal iGaming platforms in this guide, as well as what states you can legally play in.
You may see offshore casinos offer welcome packages with bonus spins, but you should know the risks you take by utilizing an offshore casino.
Offshore casinos aren’t held to legal standards like the regulated platforms in the US. They can’t be held to actually supplying you with the bonus spins they promote once you sign up. There is no regulatory board or commission you can file a complaint with if the offshore casino doesn’t hold up to its end of the deal
The same goes for any issues with the bonus spins. If a spin crashes the game or if winnings from the spin are not properly sent to you, you don’t have any options for holding the offshore casino to a legal responsibility.
You don’t have to worry about that with legal US online casinos.
Online Casino Bonus Spins FAQs (2026)
Online casino bonus spins are spins you can use on a featured slot game at no cost to you.
Both terms can mean the same thing. Bonus spin is more often used when talking about an online casino promotion, as many slot games feature free spins within their game mechanics. A bonus spin is at no cost to you, while free spins won during a slot game still occur while using your funds to make the spin.
Most online casinos offer bonus spins as part of their welcome package for new customers. They range from 100 spins, all the way up to 1,500 spins, which is currently being offered by FanDuel Casino.
Most bonus spins do not have a wagering requirement. Whatever winnings you get from them, usually are yours to keep. If bonus spins have a wagering requirement, they are usually on the low end, ranging from 1x-5x.
Sometimes you won’t have a choice for what games to use bonus spins on, but if you do, look for slots with high RTP like Blood Suckers, or with high volatility, which offer bigger payouts, like Cash Eruption slots and Huff N’ Puff slots.
Yes. Bonus spins typically do have an expiration date. That can be as short as 24 hours and as long as multiple weeks. Be sure to read the terms & conditions of any offer you accept that include bonus spins.
