Online Slots Bonus Codes 2023

The final numbers are yet to be released, but gambling revenue in the United States looks set for another record-breaking year. While Nevada is still the main moneymaker, Pennsylvania and New Jersey are closing the gap.

This is likely because both states also have thriving online casino industries generating record revenues. As a whole, online casinos are only legal in six US states (NJ, PA, WV, MI, CT, and DE). Still, iGaming revenue for the first half of 2021 ($1.66 billion) whizzed past the $1.55 billion collected over the entire 12 months of 2020.

Slot machines and online video slots are proving they still have massive pulling power with nearly a 20% leap in total revenue compared to 2019. Of course, there are several differences between land-based and online slots, such as massive deposit welcome offers, free spins, and no deposit slots bonus codes for online players.

This guide is jam-packed with everything you need to know about online slots promo codes, the different bonuses, how to claim the offers, and the all-important wagering. Let’s get started with our hand-picked list of the best casino slots bonuses specifically designed for players who enjoy spinning the reels.

Top 10 Casino Slots Bonus Codes

Slot bonuses come in many shapes and sizes, which means they fulfill the desires of all online casino players. Check out our top 10 to find your favorite offer. It’s worth noting that you can play other games with some slot casino bonus codes. Therefore, if you like to mix things up every now and then, you’ll find these casino bonus offers most attractive.

Best 5 Slots Bonus Codes No Deposit

No deposit bonuses let online casino players enjoy the thrills and excitement of real-money gambling with house money. Essentially, these are like a ‘try before you buy’ bonus, so you can get a taste for the online casino platform or app before getting your wallet out. The majority of no deposit bonus codes are slots free spins. Check out the table below to find the best offers for your state.

What Slots Promos are there at Legal US Casinos?

Slots promotions have been around since the advent of online casino bonuses. However, as competition increased between sites, operators started to think outside the box and create more innovative promos. Today, there’s a rich assortment of slot promo code offers to pick from, including:

Free Spins Promo Codes

Ultimately, all casino slots bonuses are free spins of some description. However, this is slightly misleading as you may be required to make a deposit to get them, so they aren’t quite free. That said, if you intend to fund your account, it’s worth grabbing some free spins promo codes as they add more value to your gaming experience.

Typically, slots free spins codes can be used across all devices and platforms. Although sometimes there are exclusive deals for mobile app users. This is something to keep an eye open for when claiming an offer.

Welcome Slots Deposit Bonus Codes

At America’s top online casinos, you’ll discover a couple of offers where you can use welcome slots deposit bonus codes. One of the most common is a deposit match welcome bonus offer with slots free spins added to the package, such as the current welcome package at PartyCasino of 100% up to $500 plus 20 free spins bonus to play Melon Madness Deluxe.

Another type of welcome slots deposit bonus is when the casino awards players free spins only. As an example, the offer could be ‘deposit $10 and get 100 free spins’. Normally, with such bonuses, the playthrough requirements are generously low, giving you a better chance of winning real money.

No Deposit Slots Bonus Codes

It’s little surprise that no deposit slots bonus codes are always in high demand. Basically, these offers give players a risk-free swing of the bat. You may wonder why online casinos would serve up these bonuses; however, they are the perfect win-win scenario for both players and operators.

From a player’s perspective, all they have to do is register an account and enter the slots promo codes no deposit in the process. After verifying their mobile number, they receive a risk-free bonus. For the licensed casino operator, it is playing a numbers game. While many players will use the bonus and leave, a percentage will stick around and make a real money deposit. This is especially true among sweepstakes casinos, such as Stake.us and its slot selection, where a no deposit bonus is only the beginning of a player’s journey.

Free Spins No Deposit Promo Codes

With free spins no deposit promo codes, players can usually snap up between 10 and 50 free spins, depending on the casino. While the value of each free spin is only $0.50 (or less), it’s still a great opportunity to spin the reels on some iconic slots without having to dip your hand in your pocket.

Of course, the online casino operator is running a business, so most no deposit bonuses come with a few terms and conditions, such as wagering requirements and a maximum win limit. However, several sites will pay out if a player lands the jackpot. In a nutshell, free spins no deposit bonus codes offer you the chance to win real money, which is one of the reasons we enjoy going to the casino.

Wager-free Slots Promo Codes

Wagering requirements, which we’ll explain in more depth further down this page, are what stands between players getting their hands on the bonus winnings. However, wager-free slots promo codes remove this obstacle, and any winnings generated from the free spins are paid out in real money. Check out the best FanDuel Casino slots for an idea.

Also known as no wagering free spins, it’s easy to see why these online casino bonus offers are so popular. Wager-free slots spins can be for new and existing players. For instance, some brands have no wagering on all of their free spins promos, whereas other sites may only give wager-free spins with the welcome offer.

Slots Bonus Codes for Existing Players

Don’t think for one second that only new customers get to feast on casino promotions, as slots bonus codes for existing players are your ticket to regular ongoing rewards. It depends on your chosen casino as to whether or not a bonus code is needed to claim the weekly offers, however.

Among the most popular bonuses for returning players are reload (deposit match) offers, weekly free spins, cashback, and prize draws. You can find some great value deals if you look around because the new online casino is eager to keep you as a customer rather than you leaving to play elsewhere.

How We Pick the Best Online Casinos Slot Bonus Codes

During our search for the best online casinos with slot bonus codes, we used a few criteria for our selection. These include:

• Proper License: Our experts first check to make sure the casino is properly licensed and regulated in the US. It needs to be licensed by the bodies of the state it provides its services. This is non-negotiable since a license ensures you are safe and secure when you play. Also, it is a guarantee that you’ll get your bonus offer since there is a regulatory body overseeing the site.
• Value of Slots bonus offer: Our experts check out the value of bonuses and rank those with a better value higher than others. We also ensure the wagering requirements attached to the bonuses are fair. This is because some online casinos offer slot bonus code offers with unfair wagering requirements. If you claim this type of offer, you may end up not being able to meet the requirements and even lose the offer. Only casinos that perform excellently in these areas make it to our recommended list.
• Powered by top developers: Even though your aim is to find the best slot bonuses, it is also important that only reliable developers power the games on the platform. This will ensure that you get the best experience when playing with your bonuses on the platform.
• Payment options: We expect to see numerous payment options on the site. This way, when you land a win with your bonus, you can easily withdraw your earnings. It can be frustrating to win funds with your bonus offer only to realize there is no payment option available to withdraw your earnings. In addition to variety, the available payment options should be from reputable sources like Visa, Mastercard, PayPal, etc.
• Efficient support team: Regardless of how great an online casino site is, you may sometimes run into issues you’ll require help with. Therefore, our experts check out the customer support options available on the site. We expect to see options like email, live chat, and telephone support.

How to Claim a Casino Slots Bonus

While each online casino and casino app has its own design and layout, the process of registering an account and claiming a slots deposit bonus is fairly standard. Here’s a general guide to demonstrate how quick and easy it is.

Claiming No Deposit Bonuses

1. Use our tables and lists to compare the top US online casinos and select your favorite no deposit bonus.
2. Click the ‘Claim Bonus’ link, and you’ll be redirected to your chosen site.
3. Hit the ‘Sign Up’ or ‘Join’ button.
4. Complete the registration form with all the required personal and contact details.
5. Verify your account – this is usually done by confirming your phone number and/or email address.
6. Once you’ve completed those steps, the online casino bonus will be credited to your ‘bonus money wallet’. If the offer is for free spins, you’ll need to load the applicable slot to play the free games.

Claiming Deposit Bonuses

Claiming a deposit bonus is essentially the same as outlined above with a couple of extra steps.

1. Choose a deposit bonus offer from our table and click the button to visit the casino.
2. Register and verify your account.
3. Go to the banking section and select the payment you want to use.
4. Make your first deposit.
5. At most online casinos, your bonus is added once your real money deposit is credited to your account.
6. It’s time to play your favorite casino games and slot machines.

Where to Enter the Bonus Code?

There are no hard and fast rules as to where you must enter your slots bonus code; however, it will more likely than not be in one of these sections.

• During registration – In our experience, the majority of sites and apps provide a field in the registration form where players can enter their promo or casino bonus codes.
• In the ‘Bonuses’ area – When you log in to your account, you’ll have a bonuses section within your profile (My Account). Some operators ask players to visit this page to activate the offers they want. You can also use your casino bonus codes here when required.
• When depositing – The third most likely location for entering a bonus code is when you are making a deposit. Instructions and on-screen prompts will always be provided so that when you add funds to your account, you’ll be asked if you want to claim a specific offer and to enter the necessary casino bonus code.

Winning Real Money with Slots Promo Codes

Although all types of gambling should be viewed as forms of entertainment, players engage in this activity to try and win some money. Slots promo codes can help you achieve this by unlocking the best deals at US online casinos.

However, it’s important that you read and understand the terms and conditions, as these determine if the online casino bonus is good value. Here’s an introduction to the main points you’ll come across in the t&cs:

Rollover/Wagering Requirements

Over everything else, wagering requirements govern the likelihood of players banking some cash from casino bonuses. Also referred to as rollover or playthrough, wagering requirements are typically attached to matched deposit bonuses and winnings from free spins.

An example is Borgata offering 100% up to $1,000 with a 15x wagering requirement on the bonus dollars. Let’s say we deposit $100 and therefore claim a $100 bonus. This bonus cash must be wagered 15 times ($100 x 15 = $1,500). In effect, you must keep rolling it over until you either hit the target of collectively betting $1,500 or you get wiped out and lose.

Whereas Borgata’s wagering only applies to the bonus dollars, some casinos state that the wagering requirement is the combined value of the deposit and bonus. For example, 100% up to $1,000 with 10x (deposit + bonus) wagering.

At a glance, the 10x looks more appealing than the 15x, but because the deposit is included, the total rollover requirement would be (on a $100 bonus): $100 + $100 ($200) x 10 = $2,000.

In summary, lower rollover requirements tend to equal better value for the player. So always keep that in mind. Also, be careful of promotions that do not disclose the exact wagering requirement, like the Sunrise Slots no deposit bonus, as there’s a good possibility it’s either very steep or that the bonus comes with otherwise impossible requirements.

Expiry Date

Casino bonus codes can have a few expiry dates that you need to take note of. Firstly, when you register an account, you may only have a certain number of days to claim the bonus (or activate it). This is usually done by making a deposit.

Following that, if the offer involves free spins, these will only be valid for a limited time, such as 24 or 72 hours. If any spins are unused, they will expire.

The last expiry date is the length of time a player has to clear the wagering requirements. This can range from a few days up to one month. Usually, we prefer the longer time frames so that there’s no rush and you can explore more games that you enjoy playing.

Bonus Max Cap

Some online casino bonus offers have a maximum win cap. More often than not, you’ll see this stipulation with no deposit registration bonuses. For instance, the casino gives you $25 in free credits, but the most you can withdraw from this bonus is $250.

You can also find max win caps on deposit bonuses, where the operator states players can only win five or ten times the amount they initially deposited. Clearly, this has an impact on the player’s win potential and overall value of the bonus. However, this doesn’t apply to all offers and all casinos, but it’s something to look for in the terms and conditions.

Qualifying Online Slots

Qualifying slots can refer to the games you can play using free spins or the slots you can play to clear a bonus’s wagering requirement. For free spins, these can only be used on one or a small selection of slots. To activate them, you simply load the game and play.

Online slots that contribute towards the wagering can also be known as qualifying games. For instance, Borgata’s generous deposit bonus doesn’t allow progressive slots to be played with bonus funds. Therefore, these slots obviously don’t qualify.

Max Bet Per Spin

An old trick used to be that a player would receive their online casino bonus and place one big bet. If they got lucky, they would clear the wagering and bank the free cash. To counter that tactic, casinos now limit how much a player can bet per spin.

Most sites set their limits between $5 and $10. We always advise betting the maximum limit when using bonus funds because the payouts are much higher if you trigger an in-game feature, such as a free spins round, which will help clear the wagering.

5 Best Free Slots with Bonus

Whether you use a bonus code or not, there are many outstanding slots you can play with the free cash you get from the casino. This is just a taster of the top titles you’ll come across at legal US casino sites.

2. 🥈Jin Ji Bao Xi: Endless Treasure Slot
3. 🥉9 Masks of Fire Slot Game
4. 🎖️Guns N’ Roses Video Slot
5. 🏅The Price is Right Slot Game

1. Divine Fortune Megaways Slot

The original Divine Fortunes was a massive hit for NetEnt, and now the game has been remastered with a Megaways twist. This slot has six reels and 117,649 ways to win. It brings back the magic of the popular falling wilds and wild on wild features. In addition, there are in-game free spins with stacked wilds and explosive wins due to the Megaways game mechanic.

2. Jin Ji Bao Xi: Endless Treasure Slot

From Vegas to Atlantic City, all good casinos have this slot machine. The online version packs just as many thrills and features, so it feels like you’re playing in a physical venue. Endless Treasure is a 5-reel video slot with 243 ways to win and four progressive jackpots.

The game has a unique feature that allows players to upgrade the animal symbols to golden equivalents that are worth far more. There is also a free spins feature and a possible 15,400x non-progressive jackpot waiting to be won.

3. 9 Masks of Fire Slot Game

Developed by Microgaming, 9 Masks of Fire is among the favorite games for slot players. By modern standards, the layout is fairly basic, with 5 reels and 20 paylines. However, the gameplay is extremely smooth and there are enough features offering bonuses. These include the mask scatter that can pay up to 2,000x your bet and the free spins wheel where you could win anything from 10 spins with a 2x multiplier up to 30 spins with a 3x multiplier.

4. Guns N’ Roses Video Slot

Another top slot to play with your casino bonus is Guns N’ Roses. Themed on the popular rock group, this 20-payline video slot arguably has the greatest soundtrack of all casino games. There are no fewer than seven bonus features, including expanding wilds, random multipliers, coin win (10x – 30x your bet), and free spins. The RTP is 96.98%, so Guns N’ Roses offers great value, and it can be a good slot for clearing wagering requirements.

5. The Price is Right Slot Game

Based on the iconic game show, The Price is Right is a 5-reel, 25-payline slot game by IGT. While it lacks some of the cutting-edge graphics you’ll find with newer titles, it’s still one of the most popular games in the lobby.

The features are themed on the show, so you have Punch a Bunch, Plinko, and the thrilling Cliff Hangers’ free spins with multipliers. Complete with all the catchphrases and other elements of the TV show, this is a must-play with your bonus cash.
