Eternal Slots Sister Sites

So far, there are two sister sites to Eternal Slots that are very similar in style and offering. Both Mr. O and Goat Spins are modern, exciting brands featuring RTG slots and targeting players from the U.S. In addition, Eternal Slots’ sister sites offer similar “no rules” bonuses and no deposit promotions to keep players engaged. (Although to clarify, Mr. O does not offer any free bonuses but does welcome new customers with the same 111% no rules bonus.)

Overall, we don’t see any major differences between these casinos, meaning if you’re happy with Eternal Slots, Mr. O and Goat Spins should feel like a perfect fit.

Visit SiteMrO Casino Review

At first glance, MrO looks like a very attractive site: it’s powered by the popular RTG platform, accepts U.S. players, and supports crypto payments. Plus, there are plenty of exciting bonuses listed on its promotions page.

It would be reassuring to see more information about the site’s management and licensing to be 100% confident you’re playing at a safe casino for Americans. However, it’s worth noting that keeping this information limited is fairly standard practice among U.S.-facing casinos.

Overall, MrO is a decent option, offering a 111% no-rules welcome bonus with no max cashout.

P.S. While the bonus is called “no-rules,” there are still a few conditions to be aware of, so make sure to check the details!

Visit SiteGoat Spins Review

Goat Spins was launched in 2024 by an unknown company that popped up in 2023. The company has launched two other casinos, Mr O and Eternal Slots. Goat Spins and its sisters target players from the US by offering a full portfolio of RTG games. It would be great to see more information about the management as it is very hard to say if Goat Spins is a reliable brand or not.

Goat Spins was launched in 2024 by a little-known company that emerged in 2023. In addition to Goat Spins, the same operator has introduced two other casinos—Mr. O and Eternal Slots. All three brands focus on U.S. players, offering a full suite of RTG games. However, more transparency about the company’s management would be helpful, as it’s difficult to determine whether Goat Spins is a trustworthy brand.

We can only hope Goat Spins proves to be a safe and reliable option for American players. So far, it checks all the right boxes: generous bonuses, a complete lineup of RTG slots, and crypto-friendly banking. Upon signing up, new players receive an exclusive 75 no-deposit free spins bonus (code: 75SLOTS) and a 175% welcome bonus on their first deposit (code: SLOTS175).

Bottom line: Goat Spins appears to be a modern, U.S.-friendly online casino. But don’t let the big bonuses distract you—always make sure to read the terms and conditions carefully.

Similar RTG Casinos to Eternal Slots

We’ve added five great alternatives to Eternal Slots that are proven to be safe and reliable options for U.S. players. Some are newer, while others have years of experience, but what they all share is their strong popularity and trusted reputation among players.

Slots Ninja and Slots Room are two sister sites from the Casino Max family. Both offer incredible promotions—much higher than anything available at Eternal Slots. While they don’t currently offer free bonuses, the quality of the casinos speaks for itself, meaning they don’t need giveaways to attract new customers. For example, Slots Ninja offers an outstanding 500% bonus on your first deposit! It’s a fantastic promotion with fair terms, giving you the perfect opportunity to fully enjoy the RTG games library.

If you’re still on the hunt for a no-deposit bonus, Limitless Casino might be the perfect fit, offering 100 free spins! While it’s not quite as large as a $77 free chip, it still gives you a great chance to get a feel for the site. Limitless is a trusted brand from a well-known company, powered by RTG, with a strong focus on crypto payments. Plus, they aim to process all cashouts in under 10 minutes—an impressive advantage for players who value speed.

Visit SiteSlots Ninja Review

Given the huge success of Casino Max and Spinifinity, it is no surprise that the company keeps treating players by releasing new brands. The main focus of the Slots Ninja is quality slots by RTG, an essential software developer for the US market. Nevertheless, customers will also be able to enjoy live dealers with Visionary. 

Slots Ninja’s biggest attraction is its welcome promotions. We definitely recommend trying the site with crypto as you will get a boosted offer: a 500% match on your first deposit. If you decide to stick to Fiat, you will still get a very lucrative promo: 350% on slots that you can use 4 times!

In no time, Slots Ninja will become one of the go-to places for American players who enjoy quality games and fast withdrawal times.

Visit SiteSlots Room Casino Review

We were so happy that the Casino Max family launched another U.S. site. Like its sister sites, Slots Room is powered by RTG. This means there is a good selection of slots and table games from this popular software provider. The company is well known and reliable, so we knew from the start that Slots Room would be a hit.

Start off with a huge welcome bonus that gets as high as $10,000 with an additional 200 free spins! Your first deposit will be matched with 200% up to $2,000. Do not forget to use the code: WELCOME200.

One of Limitless Casino’s standout features is its unlimited cashouts, which are advertised as being processed within minutes. While it may take longer due to verification and other factors, the cashout times are still faster than those of most other sites.

Limitless Casino also boasts amazing bonuses and promotions to keep players coming back. For instance, you can grab 100 spins when you sign up using the code LIMITLESS100.

Visit SiteIgnition Casino Review

In a few words: if Bovada is the most popular gambling site in the US, Ignition is the most popular casino site. Ignition was launched solely as a casino but it became also a Poker Room, however unlike in Bovada, in Ignition the casino is the main thing.

Ignition is perfect for more seasoned / advantage casino players. It’s more classic in its design and layout, the bonuses are not crazy but offer great value for money. Plus you can enjoy a wide array of Live Dealer games and of course Poker tables if you like to mix things up.

Highly reputable and trustworthy.

The casino also promotes Cash Bandits, Cash Bandits 2, and Cash Bandits 3 online slots. You can claim free spins and additional balance boosts for each title. 

Software & Games

As the name hits, Eternal Slots casino is all about slots. If you like the portfolio of games developed by SpinLogic (former RealTime Gaming), you’ll definitely enjoy your stay at Eternal Slots. However, besides a rich collection of slots, you will also find table games like blackjack, roulette, poker and baccarat, video poker and specialty games. 

Some of the most popular slot series include Cash Bandits and Bubble Bubble, but you can also enjoy various other titles, starting from 3-reel classics to progressives. Top games are 5 Wishes, Aliens Wins, Big Cat Links, and Copy Cat Fortune. You can sort slots using handy filters: 3-Reel, 5-Reel, 6-Reel, or Pays Any. Each game category has sub-categories that will help you find games in no time. 

If you like table games, you can play Baccarat, Caribbean Stud Poker, Lucky 7, Tri Card Poker, European Roulette, Andar Bahar and Teen Patti. Video poker is also available, as well as specialty titles like Keno. Finally, players who like crash games can play Galaxy Blast. However, the live casino games are not available. 

Banking 

Eternal Slots online casino accepts all major cryptocurrencies. It means that you can deposit with Bitcoin, Litecoin, Ethereum, Bitcoin Cash, Solana, BTC Lightning, Binance, Tron and Dogecoin. The casino supports the ERC20 network, thus ensuring safe and seamless crypto transactions. The minimum deposit amount is 0.0003 BTC, equivalent to $10. If you prefer fiat payment options, you can use Visa and Mastercard. 

You can cash out only with Bitcoin and Litecoin, and the minimum withdrawal amount is $20, or crypto equivalent. On the other hand, the maximum cashout is $4,000 a week for regular players, while the VIP players on the hugest level, Alchemist, can withdraw up to $12,000 per week. 

Summary

As we have mentioned before, Eternal Slots is a mixed casino. It does have everything to make players happy, but we believe that we need more time to have a solid option about it. It was only launched in 2024, so it might be too early to judge. Hope it keeps improving and we see more transparency regarding its company and license.
