Crazy Gorilla Boom Demo & Slot Review

Crazy Gorilla Boom Review

Well, does anyone still remember Crazy Monkey by Igrosoft? Someone probably does, but a release from 2009 already feels like ancient history, and you are not exactly going to see it sitting in every modern casino lobby. Still, the old monkey had a pretty memorable bonus game built around pulling ropes, and that was easily one of the things people remembered it for.

So, if the urge to revisit that kind of monkey shenanigans suddenly hits, Crazy Gorilla Boom by Spin Joy Games is a pretty fitting answer. It picks up that same idea and runs with it. The rope-pulling bonus is still here, while the rest of the game adds newer features, extra modifiers, and a much more active mascot around the reels. So the old formula is still easy to recognise, just pushed much closer to current slot standards.

Spin Joy Games - Slot Developer

Spin Joy Games launched in 2024 and lists Limassol, Cyprus as its base. The studio may be a recent addition to the market, but the team behind it says its gambling industry experience stretches back to the 1990s. Slots make up the main part of the catalogue, with development ranging from familiar reel games to releases built around more involved bonus systems and less conventional formats. Crash and instant-win games are also part of the portfolio.

Europe is one of the studio’s active regions, with LATAM and MENA also getting plenty of attention. Southeast Asia has joined that list during the company’s recent expansion. The LATAM footprint is already fairly specific, with Spin Joy Games content distributed across markets including Colombia, Ecuador, Chile, the Dominican Republic, and Argentina.

Slot Theme And Storyline

The presentation in Crazy Gorilla Boom works pretty well. Spin Joy Games sticks to a jungle setting, with dense greenery in the background and a monkey temple sitting behind the reels. The grid itself uses dark green panels framed by leaves and vines, while fruit, coconuts, tropical birds, and snakes make up most of the regular symbols.

The real highlight is the gorilla sitting beside the reels. He reacts to wins and feature activations, and several mechanics actually involve him, so the mascot feels connected to the game instead of being parked there for decoration. The artwork is decent overall, although some of the animations look a bit rough. Sound design fares better, with a fitting jungle-style soundtrack and effects that match the different reel events.

Crazy Gorilla Boom Rules and Gameplay

The base game keeps things pretty basic. Crazy Gorilla Boom runs on a 5x3 grid with just 9 betways, so there is not much to unpack here before the features start doing the heavier lifting. Wins are formed from left to right across consecutive reels.

The demo accepts bets from 1 FUN up to 200 FUN per spin. Since FUN is only used for free play, real money limits will vary between casinos and currencies.

Symbols And Paytable

Nothing too exotic in the special symbol department here. Their roles are pretty easy to grasp, with regular substitutions on one side and feature triggers on the other.

Wilds

Wilds stay on reels 2, 3, and 4, so you will never see one on the outer reels. Once in play, they can replace any regular paying symbol needed to complete a win. Scatters and Bonus Symbols are excluded.

Scatters

Scatters can show up across all five reels. Get enough of them on the grid and you are sent into Free Spins.

Bonus Symbols

Reels 1, 3, and 5 are where Bonus Symbols can land. Hit the required combination and the Bonus Game starts.

Crazy Gorilla Boom Bonuses and Special Features

As you can probably guess by now, Crazy Gorilla Boom has two main bonus rounds: Free Spins and a separate Bonus Game. Seeing both in one slot is hardly rare these days, though I still like having two different routes into the bonus action. A few smaller mechanics sit around them as well, giving the game enough going on without turning every spin into a feature checklist.

Free Spins

Landing 3 or more Scatters starts the Free Spins round with 10 spins. There is no retrigger, so those 10 spins are all you get, and regular wins still follow the same rules as in the base game.

The main addition here comes from Chest Symbols. These work as cash prizes and do not need any collector symbol to pay. When a Chest lands, the gorilla jumps in, smashes it open, and the value inside is added directly to your win.

Bonus Game

The Bonus Game starts when Bonus Symbols land on reels 1, 3, and 5 at the same time. Inside, the reels disappear, and you get a picking round built around 5 ropes.

Each rope can reveal either a banana carrying a cash prize or a brick. Bananas add their values to the win, while hitting a brick normally ends it. Pull all 5 ropes without finding one and you get one final choice between two boxes. Both contain a guaranteed cash prize, with one box hiding the larger value.

There is also a Hard Hat modifier. With it active, the first brick no longer ends the Bonus Game, essentially giving you one extra life. A second brick still finishes the round. The Hard Hat is added automatically when entering the Bonus Game through the corresponding Bonus Buy or Boost option.

Gamble

Any regular win can be taken into the Gamble feature. You choose between two card suits, with a correct guess doubling the current amount and a wrong one wiping it out. The process can be repeated up to 5 times.

Bonus Buy

The Bonus Buy menu gives direct access to either of the two main rounds:

• 70x bet - starts Free Spins;
• 70x bet - starts the Bonus Game with the Hard Hat already active.

Boost

Boost works as the bonus bet menu and changes the chances of landing the two trigger symbols. Three settings are available:

• 5x bet - increases the chance of landing Scatters;
• 5x bet - increases the chance of landing Bonus Symbols, with the Bonus Game starting with the Hard Hat;
• 10x bet - increases the chance of landing both trigger symbols, while the Bonus Game also starts with the Hard Hat.

Crazy Gorilla Boom RTP, Volatility, and Max Win

The RTP situation deserves attention here. Spin Joy Games supplies 88%, 92%, 94%, and 96% versions, which is a pretty massive gap from one end to the other. Check the figure shown by the casino before playing for real money.

Volatility sits at Medium, while the win cap is 5,000x. For a game in this bracket, I am perfectly fine with that number.

40 Wild Gobbler Demo Version and Free Play

You can launch the 40 Wild Gobbler free play here on SlotCatalog without registration or a deposit. The demo uses virtual funds and keeps the same 5x4 grid, 40 paylines, Mystery Collection feature, Free Spins with Wild collection, progressive jackpots, and Gamble option.

The demo is especially useful for checking how much of the game revolves around the collector setup. You can see how often random Wild drops appear in the base game, how Coin values are added, and how quickly the Wild thresholds build during Free Spins before moving on to real money play.

40 Wild Gobbler is also available on mobile devices, and the 5x4 setup does not ask for much screen space. The symbols remain easy to distinguish, while the Coin values and Wild activity can still be followed without zooming in.

Free Spins use the same layout, with the Wild collection progress and multiplier levels kept close to the reels. That matters more here than the regular paylines, since most of the bonus revolves around watching Wilds land, collect Coins, and push the meter toward the next 10-spin upgrade.

Strategy & Tips For Winning

Crazy Gorilla Boom leaves the outcomes to RNG, but a few choices can help stretch the balance and avoid unnecessary losses.

• Choose the 96% RTP version. The game can run at 88%, 92%, 94%, or 96%, so this is the most important setting to check before playing.
• Keep the stake lower when using Boost. The 5x and 10x options increase the cost of every spin, so adjusting the base bet first helps keep total exposure under control.
• Use the 5x Boost when chasing one specific bonus. There is little reason to pay 10x if you only care about Free Spins or the Bonus Game.
• Skip Gamble when you want to protect a good win. One wrong suit pick wipes out the amount taken into the feature.
• Treat the 70x Bonus Buy as a separate budget decision. It gives instant access to a bonus round, but repeated buys can drain the balance much faster than regular spins.

Pros And Cons Of Crazy Gorilla Boom Slot

Similar Slots To Try

For something different from Crazy Gorilla Boom, Spin Joy Games has a few releases that head in very different directions. Only Granns goes for a cute instant-win setup, Meduza's Fortune scales things up with a massive Cluster Pays grid, while Kinky Spinky builds most of its appeal around multipliers.

• Only Granns swaps regular reels for a cute instant-win format built around a knitting granny. It is a good pick if you want something much simpler and more casual than Crazy Gorilla Boom.
• Meduza's Fortune uses a Greek theme and a huge 7x7 grid with Cluster Pays. Its feature set is more familiar, but the larger layout gives the gameplay a very different feel.
• Kinky Spinky takes a more adult-themed route and puts multipliers at the centre of the gameplay. It makes sense as an alternative if you prefer a mechanic-heavy setup over mascot-driven features.

Final Words

Crazy Gorilla Boom is far from the fanciest release in the jungle, but I still liked it. Part of that comes from how Spin Joy Games handles the gorilla itself, but there is also a nice bit of old-school DNA underneath. The rope-pulling Bonus Game brings back one of the most memorable parts of Crazy Monkey, so this feels more like a proper follow-up to that idea than another jungle slot wearing a familiar theme.

At the same time, the game does enough to move that old formula forward. Free Spins, Chest prizes, the Hard Hat modifier, Boost options, and a much more active mascot bring the setup closer to current standards without burying the original idea under too many extras. Add Medium volatility and a 5,000x cap, and the result is a pretty solid modern take on a very old monkey formula.
