3 Oaks Slots & Online Casinos

Nope, 3 Oaks is not an off-the-grid farm where you can play slots with vegetables instead of fruit symbols. 3 Oaks is a legit developer of online slots that is making a comeback under a new name. Until recently, it was known as Booongo. The company clocked in more than 50 games that were distributed across a wide range of markets.

I’ve had multiple hot streaks on various games under both labels. 3 Oaks does a great job with the standard payout mechanics, but its forte is the Hold & Respin bonus game. You can find a decent number of “Book of” slots with special expanding symbols and just about any payline layout you can think of.

Was it hard choosing the top 3 Oaks slots from a list of 75 titles? You bet. But first, let me tell you where you can find these games in the US.

Legal & Safe 3 Oaks Casinos in the US

3 Oaks Gaming slots appeared on the US online casino market a few years ago. Standard online casinos are yet to strike a deal with the company, but this still leaves about 48 US states where you can play 3 Oaks slots.

I am talking about legal, legit sweepstakes casinos where you can play online slots and casino games for fun or make free sweepstakes entries to win cash-redeemable coins. Some of the sweepstakes and social casinos where I’ve played many different 3 Oaks slots are:

1.5M WoW Coins + 35 Free SC
GET UP TO 367,000 GC + FREE 32.3 SC
Unlock 57,500 GC + 27.5 FREE SC

What’s common for all of the above is that they provide daily promos and attractive sign-up bonuses for new players. If you fit this description, you can discover the best 3 Oaks slots, the most attractive RTPs, and bonuses, and head on to claim a fresh bonus.

5 Best 3 Oaks Online Slots

Want to play some of the best online slots released by 3 Oaks? I delved into a large sampling to find the ideal combination of bonuses, RTP, and payout potential.

This provider takes a balanced approach with the hard specs, so you’ll find plenty of medium volatility slots on its catalog, which is available on Pulsz, WOW Vegas, and McLuck sweepstakes casinos.

#1. Queen of the Sun

Queen of the Sun

Will you join a comely demigod who is gifted at reading futures on a solar disc? The game takes you to an Aztec pyramid where your symbol sacrifice of sweep coins can shake off prizes of up to 5,000x your wager. Expectedly, volatility is high, but RTP is near average, with 95.77%

It’s a small wonder that WOW Vegas added 3 Oaks to its slots roster, considering the top payout potential of some of its best slots that you can play with a sweet wallop of 5,000 free WOW Coins on signup and 200% more coins on your first purchase.

All these coins should be enough to explore Queen of the Sun because the game has two extra features: a free spins bonus and a Hold and Respin bonus. Players are especially intrigued by the latter because it can award any of the three smaller jackpots on the same bonus round in addition to the Grand pot.

#2. Yo-Ho Gold

Yo-Ho Gold

Like I said, finding the best 3 Oaks slots wasn’t easy, but the game at hand is definitely on the top of the cream. Unlike the other four games, Yo-Ho Gold’s Hold & Respin bonus offers reel and win modifiers!

The Extender symbol can extend the playing field for up to 8 rows, meaning more room for paying bonus symbols. The Collector icon picks up all the values and adds them up, essentially doubling your loot up to that point.

Two other modifiers can bring about a wild bonus in this vibrant pirate-themed adventure. You can play it at McLuck Casino. Claiming the McLuck signup bonus puts 7,5000 Gold Coins + 2.5 Sweeps Coins in your account.

Another awesome detail? Yo-Ho Gold is the highest-paying 3 Oaks game with 25,000x your bet, balanced with a highly volatile RNG.

#3. Black Wolf

Black Wolf

Join the majestic black wolf on the reels of this 25 payline slot with a 1,000x bet grand jackpot. Unlike most Hold & Respin bonus slots, the game at hand has four rows with five reels, leaving plenty of room for Wilds and Bonus symbols.

The game offers large bonus symbol values that come to the fore during the respins bonus. You can land four jackpot tiers, three of which can land attached to a symbol. 3 Oaks have added a kicker: one of the orb symbols is a Booster that sums up the visible bonus multipliers in the base game!

Black Wolf Hold and Win are ideal for players who prefer medium volatility, with a solid RTP of 95.65% matches. You can find the game among Pulsz Casino slots, with the sweepstakes casino offering a signup bonus of Free 2.3 Sweeps Coins + 5,000 Gold Coins – no bonus code required.

#4. Book of Sun Multichance

Book of Sun Multichance

Hands down, this is the best Book of Style online slot from 3 Oaks and other providers as well. The first two games were great, but the third of the series is a lot more explosive with 10,000x bet max win and 95.40% RTP.

You can expect the usual, which is definitely not a bad thing in this game. The special symbol lands super-stacked in the free spins bonus, for which you need three golden book symbols.

Moreover, the special symbol pays scattered wins. If three stacks land on non-adjacent reels, you still get a win of the same amount of times your bet. WOW Vegas has Book of Sun Multichance, and players love it for its ability to retrigger the FS bonus.

#5. Olympian Gods

Olympian Gods

3 Oaks offers a slightly smaller RTP for this game (94.80%) but you can watch it being offset by Wilds that can stack reel-high. There is a major kicker for the base game and for the free spins bonus in this ancient Greece-themed adventure.

We’ve had three scatters awarding 10 spins, and these can retrigger multiple times when luck serves you well. Another feature that is absolutely bonkers is that Olympian Gods has 50 paylines.

This layout works marvelously with the stacked Wilds – excellent news for players who want to have a brief session that may or may not lead to a quick bonus game. This is another medium-volatility game that you can play at WOW Vegas.

Highest RTP Slot Games by 3 Oaks Gaming

Return to Player is an important metric for the distinguishing player because it gives you an idea of what percentage of your bets will be potentially returned on aggregate. The RTP figure doesn’t represent a limit but a watermark of averages.

In some cases, a big win can blow the RTP past the average many times over. Let’s consider the ten 3 Oaks slots with the best RTP.

For reference, I also added a column for volatility levels to help you choose the best of both worlds. Thankfully, 3 Oaks presents us with a balanced choice of volatility levels, so every kind of player will find the game that best fits their approach.

3 Oaks Slots and Games Features

In a crowded field of game providers where several iGaming software companies dominate by sheer size and output, smaller companies are no less innovative. 3 Oaks is one of the best examples of a company that stayed on the radar. And what’s its magic sauce? Hold & Respin bonuses.

If you are not familiar with the bonus, you should correct that mistake by playing a 3 Oaks slot at one of the sweepstakes casinos listed on this page. Signup bonuses are aplenty so that you can head to some of the best legal casino sites in the US.

Hold & Respin

Hold & Respin bonuses became big right as the Megaways hype began to plateau. This bonus game is attractive because of the “sticky” symbols and respins. More than half of 3 Oaks’ arsenal consists of Hold 7 Respin slots.

Each bonus symbol that lands on the reels remains in place and resets the number of respins to the starting point, which is usually 3. This way, the player is given a chance to fill the layout with as many bonus symbols as possible.

Most games can serve a mini or minor jackpot attached to the bonus symbol. Typically, filling all positions results in a jackpot prize. In summary, it’s virtually impossible not to win a prize because the re-spins begin with sticky symbols, which are those that trigger the bonus.

“Book of” Slots

Reading is awesome, but I am not talking about that kind of book here. For a long time, the world of online slots was in a “Book of” craze, with dozens of Egypt-themed slots being released each month. 3 Oaks didn’t buck the trend, and they were right. Today, you can find several games with a supercharged “book” symbol, such as Book of Dead, Book of Ra, Book of Helios, etc.

The typical characteristic of this style of slots is that the Wild is the Bonus symbol, which is usually a scatter. This means this magical symbol can land anywhere on the reels to trigger the bonus game, and it can substitute every time it’s adjacent to two matching symbols on a payline.

But the best feature comes when the game chooses a random special symbol. Every appearance results in that symbol expanding on a full reel, and the RNG tends to offer more than one stack. What’s more, the special stacks pay scattered wins as well.

3 Oaks Slots RTP

This is one of those iGaming providers that can cut a perfect balance between the potential output of a bonus feature, the RTP percentage, and the volatility of any given game. My RTP overview in the table below points to a common pattern: 3 Oaks Gaming RTP tends to be around 95.60% on average.

Few casino games have it higher than the industry average of 96%. On the other hand, volatility levels are diverse, and I’m happy to say that 3 Oaks doesn’t care too much about highly volatile RNGs (Random Number Generator).

3 Oaks Company Information & Background

3 Oaks Gaming was launched in 2021. Its offices are located on the Isle of Man in the UK. The company’s success heretofore is owed to a team that has serious experience in iGaming. They are full-stack and, in addition to games, also create solutions for the iGaming industry.

Besides the US, the game provider is also available in Canada, Australia, New Zealand, Brazil, Germany, Japan, Mexico, Philippines – more than 50 countries in total. Players in the US can make sweepstakes bets, while international players can use their national currency.

3 Oaks slots appeared on the WOW Vegas catalog in April 2023. Pulsz and McLuck onboarded the provider somewhat earlier, but generally, 3 Oaks is considered a recent addition to sweepstakes casinos in the US. Nevertheless, given its output and the popularity of the games, we can expect more casinos to start including.

Few details on the technical side that some players may find interesting – 3 Oaks does platform integrations for casinos, its own stats suite, and live support for customers. Most importantly, all of the games by 3 Oaks are independently tested and certified by Gaming Associates Europe Ltd.

Sweepstakes casinos are the best option for legal casino gaming for players in the US. All but three states (WA, ID, and, in some cases, WY) have regulation that allows players to make sweepstake plays on slot games to win cash-redeemable prizes.

If you want to get familiar with any of the top sweepstakes and social casinos in the country, you can play slots for free and in demo mode, including slots by 3 Oaks. Claiming a no deposit bonus is available for every casino on the list. With all the free gold coins, you can try different games and explore the bonus features. When you find your favorite 3 Oaks slots, you can switch to the sweepstakes mode.

For instance, opening the Pulsz Casino bonus link allows you to claim 5,000 gold coins and 2.3 sweep coins when you verify your account. All of the top sweepstakes casinos reviewed on our website provide daily login bonuses or other instant promos for gold coins and sweeps coins.

There are first-purchase bonuses, too. Pulsz awards you with 200% extra coins on the GC package of your choice, WOW Vegas adds 200% extra, and McLuck Casino gives you 15 free SC for purchasing the $9.99 GC package.

It’s typical for every casino bonus to have terms and conditions. The usual terms are that you need to be 18+, a resident of a legal state, and verifying your phone and address is a must. Also, you must be a new player in order to claim a signup bonus. Otherwise, subsequent on-site bonuses and promos are available to all registered accounts.
