3 Oaks Gaming: Games, Features & Research Notes
Last verified: 2026-10-03 · Editor: SweepsDuke
3 Oaks Gaming is the name Booongo took in 2021. Green Rock Holding Limited manages the studio from the Isle of Man, with licenses from the Isle of Man Gambling Supervision Commission and the UK Gambling Commission. We look for the brand when a US sweepstakes lobby needs bright, feature-heavy slots and we do not need blackjack or roulette from the same supplier. The catalog is slots only, listed at 100+ titles. Published RTPs across the set run from 95% to 97%.
There is no US license yet, so these games are not in US real-money casinos. A player in the United States reaches them on a social or sweepstakes site that is open in that player's state. Gold Coins are the practice balance. Sweeps Coins are the prize balance, and any redemption still follows the casino's own floor, playthrough, and KYC rules. A 20,000x line on a 3 Oaks paytable does not change those rules.
The studio kept Booongo's playful, colorful look and pushed harder on theme and features after the rename. Fruit machines and candy games are still in the set. So is a cartoon bank job. Hold and Win, fixed jackpots, and a Collect symbol show up often. Megaways does not. We have two Megaways titles on file for the studio, and we do not treat the mechanic as the reason to filter for 3 Oaks.

|---|---|
| Studio | 3 Oaks Gaming, former Booongo (rebranded 2021) |
| Managed by | Green Rock Holding Limited |
| Headquarters | Isle of Man |
| Licenses | Isle of Man Gambling Supervision Commission, UK Gambling Commission |
| US real-money license | None yet |
| Game types | Slots only |
| Catalog | 100+ |
| Published RTP band | 95% to 97% (most titles sit between 95% and 96%) |
| Named testing body | Gaming Associates Europe Limited (RNG testing and audits) |
| Megaways titles | Two |
| Deepest lobby we track | KingPrize, 110 slots |
| Games we open first | Fishin' Bear, Lucky Penny, Sun of Egypt 4, Big Heist, Aztec Pyramid Megaways |
Where the deep lobbies are
When the job is "play as much of this catalog as the site actually carries," we start with five sweepstakes casinos:
| Casino | 3 Oaks slots |
|---|---|
| KingPrize | 110 |
| Spree | 103 |
| Mega Bonanza | 92 |
| WOW Vegas | 87 |
| Jackpota | 87 |
KingPrize is the lobby we open for width. At 110 games it already sits above the rounded 100+ catalog figure, so that 100+ is a floor, not a hard cap. Spree is the next stop at 103. Mega Bonanza holds 92. WOW Vegas and Jackpota sit together at 87, which is most of the catalog and not all of it. The gap between KingPrize and those two is more than 20 titles. A badge that says the casino "has 3 Oaks" is not the same thing as a full filter.
If a brand you like is missing from the table, we do not have a 3 Oaks count for it. That is not proof the studio is absent. Open the provider filter, or search a tile you already know (Fishin' Bear is an easy test), and read the studio name on the game. A slot with a similar title from another studio is a different model.
Welcome packages move faster than lobby depth. We do not pin a signup chip to this guide. Check the live store, then confirm the 3 Oaks filter still shows the games below before you buy Gold Coins to reach them.
State blocks belong to the casino, not the studio. A 110-game count does nothing if your state is on that site's excluded list. Age rules, playthrough, and the redemption floor are in the same terms.
Games we open first
These seven are the ones we actually point players at. Each note is how we would use the game, with the published math left intact.
Big Heist
Big Heist is the theme break. The reels are a cartoon bank robbery, not another pile of gems and temples. Volatility is high, so quiet stretches are part of the product. The features we use it for are Collect, Super Collect, and free spins. The max win is 3,170x stake.
We open it when a player is bored of the usual 3 Oaks scenery and can afford a dry run. We do not open it for the ceiling. Lucky Penny's 20,000x line is in a different league, and Sun of Egypt 4's 10,000x is still well above 3,170x. Size the stake so a long quiet stretch does not eat the Sweeps Coins balance you meant to redeem. On Gold Coins, the same volatility is cheap education: you learn how Collect pays before you move the session to SC.
Fishin' Bear
Fishin' Bear is the RTP pick. Most 3 Oaks titles sit between 95% and 96%. This one is listed at 96.5%. The grid is 5x3. A bear fishes from a boat over a sunny lake and can toss fish onto the reels. Four fixed jackpots sit on top of the base game.
If you care about the published return more than a huge cap, this is the first tile we tap. A 96.5% figure is a long-run note about the game math. It does not predict the next half hour, and it says nothing about your casino's redemption minimum. We still open the in-game paytable in the lobby we are in. A studio number and the build a casino ships can differ, and we want the figure on that screen before we call the session "the high RTP one."
The tone is light on purpose. Bright art and a simple grid make it a better first 3 Oaks game than a bonus-buy Megaways title. Use it to learn the jackpot labels, then decide whether you want a bigger cap elsewhere.
Sun of Egypt 4
Sun of Egypt 4 is the current entry in that series, and it is the messy one to brief honestly. It is marketed around fixed jackpots, with a five-jackpot headline attached to the name. The features on the game are Hold and Win, a Boost, free spins, a Super Bonus, and four separate jackpots. Those two counts do not match. Open the paytable in your lobby and see which pots are actually live before you chase a fifth prize.
Symbols are a golden pharaoh, an ankh, and suns. Max win is 10,000x stake. RTP is 95.47%, which is on the low side of this catalog even though it sits inside the 95% to 97% band. We still recommend the game when a player wants Hold and Win with a large printed cap and already likes the Egypt series. We do not recommend it as the "better return" alternative to Fishin' Bear. The RTP gap is real: 95.47% versus 96.5%.
Lucky Penny
Lucky Penny carries the max-win headline: up to 20,000x stake, one of the highest caps in this catalog. The setting is Irish folk. A character in green stands beside a green field at sunset and tosses a penny onto the reels, adding multipliers to random symbols. There is a free spins round, and a bonus buy that can open it immediately. No RTP is published beside those features.
We send players here when the question is "how high can a 3 Oaks sheet go?" We do not send them here for a return figure we cannot show. On Gold Coins, try the base game first and watch how the penny multipliers land. On Sweeps Coins, treat the bonus buy as a separate decision. A buy spends a large chunk of the balance that is tied to prizes. Read that casino's rule on bought features, and read whether the site caps a spin below the studio's 20,000x line. We do not have a site-cap table for this game, so we will not invent one. The check takes a minute in the rules.
Aztec Pyramid Megaways
Aztec Pyramid Megaways is the studio's first Megaways game. Cascades, free spins, and 117,649 ways are the mechanics. The art is gray stone on a dark backdrop, and it is one of the two titles we would call dated next to newer 3 Oaks work (Book of Sun is the other). Gameplay is the reason to stay, not the frame.
Some sweepstakes sites sell the free spins round at 150x stake. That price is a site build. It is not on every lobby, and we look for the button before we talk about it. At 150x, one buy is a serious slice of a Sweeps Coins balance. We would not tap it until the stake is tiny on purpose, or until we are still on Gold Coins and only want to see the round. If you came for Megaways specifically, this is the 3 Oaks version to try. If you came for the studio's usual Hold and Win loop, you do not need it.
Lady Fortune
Lady Fortune uses Pay Anywhere on a 6x5 grid. The theme is Asian folklore: a genie teapot, a tree of coins, a folding fan, gems, and the lady herself. The bonus starts at four or more scatters. During it, she applies multipliers from 5x to 500x on random symbols. No RTP and no max win are published with that feature list.
This is the one we open when a player wants a scatter-driven bonus and a wide grid, and does not need a jackpot ladder. The 500x multiplier is the exciting line, and it is a symbol multiplier inside the bonus, not a promise that the round pays 500x stake. We say that out loud because the two ideas get mixed up at the table. Play a few Gold Coin rounds, count how often four scatters actually arrive, and only then move Sweeps Coins onto it.
Coin Up: Hot Fire
Coin Up: Hot Fire sits in the Hit the Bonus series. It does not lean on base-game wins. Three symbols on the middle row start the feature. The bonus is Hold and Win, with an extra row for special symbols, multipliers, and four fixed jackpots.
We use it as a sample of bonus-first 3 Oaks, ideally on Gold Coins, before anyone spends Sweeps Coins on the shape. If dead spins annoy you, this is the product they built: the base game is a waiting room, and the middle row is the door. If you want the base game to pay on its own, pick Fishin' Bear or Big Heist instead. Easy access to the bonus is the trade for those quiet base spins, not a gift on top of a normal slot.
Hold and Win, Collect, and the rest of the toolkit
Hold and Win is the feature we see most often once we leave the Megaways corner. Winning bonus symbols stay put instead of clearing, and the round is about filling more of them before the respins end. Sun of Egypt 4 and Coin Up: Hot Fire both use it. Many other 3 Oaks games do too.
Collect is the other habit. Cash symbols sit on the grid with values. A trigger symbol gathers them and adds them to the win. Big Heist builds a Super Collect on top of that idea. It is simple to read, which is why we like it as a teaching spin for someone new to the studio.
Fixed jackpots show up in bunches of three to five, hittable in the base game or in the bonus, depending on the title. Fishin' Bear has four. Coin Up: Hot Fire has four. Sun of Egypt 4 is the one to double-check, for the four-versus-five issue above. Jackpot hunters have a real shelf here. Read the in-game rules for which pot is the small one and which is the top prize, because the names change from tile to tile.
Art direction is consistent even when the theme changes: bright colors, light music, a tone that stays playful. Newer games look cleaner. Aztec Pyramid Megaways and Book of Sun lag that standard. If a screenshot looks muddy, it may be an older tile, not a broken casino client. Launch it once on Gold Coins and decide.
The phone layout is the practical complaint. The interface is familiar rather than distinctive, and on mobile the controls sit where a thumb can raise the stake by accident. We set the bet, then keep our hands off the stake controls for the rest of the series. That matters more on Sweeps Coins than on Gold Coins. An accidental max bet on SC is a redemption problem, not a cosmetic one.
Variety stops at slots. There is no 3 Oaks blackjack, roulette, or crash game to fall back on when you want a break from reels. If your session needs table games, you need another provider in the same lobby. That is a catalog fact, not a knock on the slots themselves.
How a Sweeps Coins session should use this math
Start on Gold Coins even if the casino handed you Sweeps Coins at signup. The GC balance is there to answer boring questions: does this tile match the description, is the bonus buy actually on screen, does the paytable RTP match 96.5% or 95.47%, and can you tap the controls without bumping the stake. Ten minutes of that is cheaper than learning it on the balance you plan to redeem.
Move to Sweeps Coins with a stake you already survived on GC. For Fishin' Bear, a small stake and a longer session matches the reason we picked it (the RTP and the four jackpots). For Big Heist, keep the session short or the stake smaller again, because high volatility will show you long gaps. For Lucky Penny and Aztec Pyramid Megaways, decide about the buy before you switch currencies. A 150x Aztec buy, where the button exists, can wipe a thin SC balance in one press.
Bonus buys matter more on Sweeps Coins than on Gold Coins because SC is the mode tied to prizes. Several sweeps sites also cap what a spin can return even when the studio sheet goes higher. This guide does not list those caps. Read them in the casino terms. A 20,000x studio line and a site rule that stops a prize earlier are both real, and only the site rule governs the redemption.
Volatility language is thin outside Big Heist, which is marked high. The other games are described through features. A Hold and Win coin game and a Megaways cascade do not play like the same product just because both can sit near 95% RTP. If you need a label, use the feature: waiting for a middle-row trigger (Coin Up: Hot Fire), grinding a 5x3 with jackpots (Fishin' Bear), or buying the feature (Lucky Penny, and Aztec Pyramid on sites that sell it).
Provider filters are uneven. If the filter is missing, search the tile and confirm "3 Oaks" on the load screen. Then check the game's own rules for RTP and max win. Our figures are the published ones for these titles. Your lobby's build is the one that pays.
Licenses and fairness
The licenses we can name are Isle of Man and UK. That is a business-to-business supply story. It is not a US player license, and it does not make a sweepstakes casino legal in a state that site has blocked. Green Rock Holding Limited is the company that manages the studio. Fairness material for the group points to RNG testing and audits, including evaluations from Gaming Associates Europe Limited.
The RTP figures in this guide are the ones published for the games: the 95% to 97% band, the 95% to 96% cluster, Fishin' Bear at 96.5%, and Sun of Egypt 4 at 95.47%. If a paytable in your lobby disagrees, trust the paytable for that session and treat our number as stale until you can see why.
Sweepstakes play still has to offer a no-purchase path. Buying Gold Coins is optional. Responsible gaming tools, if the casino has them, live in the account menu, not inside the slot. A fair slot math model does not replace a self-limit, a cool-off, or a decision to stop when the SC balance hits the gift-card floor you actually wanted.
Who should play 3 Oaks, and who should skip
Play 3 Oaks if you want colorful slots, you like Hold and Win or a Collect feature, and you are happy to hunt fixed jackpots on a 5x3 or a coin-respin grid. Fishin' Bear is the sensible first game when published RTP matters. Lucky Penny is the one when you want the 20,000x headline and you will read the bonus-buy rule before you press it. KingPrize, then Spree, are the lobbies we would pick when the goal is simply to see more of the catalog. Players who already bounce between fruit themes, Egypt, and the odd cartoon one-off will feel at home. So will anyone who wants a studio they can sample on Gold Coins in a few minutes and then move a small Sweeps Coins stake onto one game, not ten.
Skip 3 Oaks if you want Megaways as a habit. Two titles is a thin shelf, and one of them (Aztec Pyramid Megaways) looks older than the games around it. Skip them if you want table games, crash games, or a live dealer from the same brand. You will not find that here. Skip Coin Up: Hot Fire, and be careful with the rest of the Hit the Bonus series, if a dead base game ruins the session for you. Skip the studio entirely if your state is blocked at the casino you were going to use, or if you need a US real-money casino license on the supplier. That license is not there. And skip the 150x feature buy on Sweeps Coins if your balance is still near a redemption floor you have not cleared. The slot will be there after you redeem.
3 Oaks Gaming Provider FAQ
Is 3 Oaks the same company as Booongo?
Yes. Booongo rebranded as 3 Oaks Gaming in 2021. Green Rock Holding Limited manages the studio. Older search results for Booongo slots usually land on this catalog.
Can I play these games at a real-money US casino?
No. There is no US license yet, so 3 Oaks slots are not in US real-money casinos. The route is sweepstakes play on a site that is open in your state. Sweeps Coin redemption follows that casino's rules, not a 3 Oaks rule sheet.
Which site has the most 3 Oaks games?
KingPrize at 110, then Spree at 103, Mega Bonanza at 92, and WOW Vegas and Jackpota at 87 each. Counts move. Filter the live lobby before you treat a number as current.
What is the highest max win?
Lucky Penny at 20,000x. Sun of Egypt 4 is 10,000x. Big Heist is 3,170x. Lady Fortune and Coin Up: Hot Fire do not publish a max win next to those features.
Does every 3 Oaks slot have a bonus buy?
No. Lucky Penny has a bonus buy into free spins. Aztec Pyramid Megaways has one on some sites, priced at 150x stake where it is sold. Coin Up: Hot Fire uses a three-symbol middle-row trigger instead of a buy button.
Are the games only slots?
Yes. The catalog is slots. If you want live dealer or RNG tables, pick another provider in the same casino.
