Rather than being created by an established game developer, these online slots games are produced by the in-house team at the online casino. This means they’re exclusive titles that can only be played by casinos belonging to the same casino ownership group.

Are Online Proprietary Slots Legal to Play in the USA?

You can play any real-money slot games available at online casinos that accept players from the USA. This includes proprietary and exclusive games offered by casinos. So, when you find these games, you can legally play them.

However, the rules regarding the legality of slots in the US vary between states. Under current US gambling laws, US-licensed online casino can only legally operate from six states. These are Connecticut, New Jersey, Delaware, Michigan, Pennsylvania, and West Virginia. Casinos accepting players from other states have to operate from an offshore jurisdiction. 

For example, Café Casino, an offshore casino with many proprietary games, has its gambling license from Curacao. Due to this, you can legally play at this casino from anywhere in the US—even in states without a regulated online casino industry.

What Makes Proprietary Slots Special?

Learn about what makes proprietary casino games special compared to other games. 

Exclusive Game Titles

Proprietary games are often exclusive to one casino or a group of casinos. Although some offer titles to other casinos, most tend to keep them exclusive. That means you must visit the specific casino to play their proprietary slots. 

In-House Made Games

Some casinos get their proprietary games from established game providers, which used to be the standard. However, nowadays, many casinos have started game studios and developed proprietary titles. One of the main benefits of producing games is that it’s cheaper long term. Another one is greater control of the final product, resulting in high-RTP slots with innovative graphics and themes.

Network Jackpots

Many proprietary slots also offer a jackpot. Most often, you’ll find that there is a collective jackpot for multiple proprietary slots. This ensures that the jackpot grows rapidly, even though it’s offered at a limited selection of casinos. For example, you’ll find many proprietary jackpot slots at Café Casino. 

How to Choose the Best Proprietary Online Casino

Choosing a great casino takes some research, and below we’ve outlined what you should look into. 

License & Security

The first check is whether the casino has obtained a valid gambling license. You’ll see this information in the footer of the casino’s website. Typically, you’ll find that the best US offshore casinos are licensed within the jurisdiction of Curacao. Also, ensure the website is encrypted so your personal and banking information is kept safe. 

Bonuses and promotions

When assessing the bonus offers at an online casino, you must look at more than just the bonus amount. The terms it comes with determine whether a bonus is good. You want to make sure that the wagering requirement is reasonable to complete and check that the maximum win amount is high if the casino has limited the maximum possible win.

Payment methods

You’ll need to be able to both deposit and withdraw money from an online casino. That’s why you need to look into the payment methods the casino offers. You want a good mix of payment options and low or no transaction fees. Pay attention to these details for withdrawals as well as for deposits. 

Game selection

The best casino apps offer an extensive selection of proprietary slots and release new slot games frequently. However, looking into the selection of proprietary slots is not enough. A great casino will offer a variety of slot machines, table games, video poker, specialty games, and live dealer games. Look through the complete collection of games to ensure it offers the types you enjoy playing.

Proprietary Online Casino Bonuses

You want to maximize your game session and bankroll when playing a proprietary slot machine. To do this, you should claim a casino bonus. Here are the most common bonus types you’ll find at US offshore online casinos:

No-Deposit Bonus

Claim a no-deposit slots bonus to win real money without risking your funds. These promotions are ones you get for free, typically as a loyalty bonus or a registration bonus. Therefore, they are are one of the best free bonuses for slots. You’ll find one such bonus at Red Dog Casino. It offers $40 for free when you register for a player account. 

Match Bonus

If you want to boost your deposit, then a match deposit bonus is the one you should claim. By depositing, the casino will offer you extra money you get for free. For example, Café Casino offers a 350% bonus of up to $2,500 on your first Bitcoin deposit. If you choose another banking method, you’ll instead be granted a 250% bonus of up to $1,500. 

Free Spins

Spinning for free with free spins is perhaps the most exciting form of casino bonus. You can be fortunate and win a large amount or unlucky and win next to nothing. Free spins are something that many casinos offer, either when you sign up or as a weekly promotion. Keep an eye on your email to get the latest free spin offers from the casinos you’re registered with. 


A cashback comes in handy if you’re unlucky when depositing and playing. This bonus gives you some of your losses back, so you can try your luck again. Often, online casinos offer daily, weekly, or monthly cashbacks. You’ll find information about cashbacks on the promotion or VIP pages at the casinos you play at. 

History of Proprietary Slots

Making exclusive games have been going on for a long time, but it was around 2015 that this became popular. This was when many of the large casino companies in Europe started making their games. Back then, they did this in cooperation with game providers. 

Some started game studios that operated alongside their casinos. These games were often exclusive to the casino in question. Then, they started offering them to other casinos, creating new verticals within iGaming operations. 

There aren’t many online casinos with proprietary slot games in the USA, but there are some. Café Casino has games through the Bodog network of casinos, including Ignition Casino, Bovada, and others. Then, operators like Stake also have their proprietary game studios. 

As technology evolves and it becomes easier to program and make games. This is why it’s expected that more and more casinos will make proprietary slots in the coming years. Exclusive games are a great way for casinos to attract and retain players.
