Play Action Boost Gorilla Gems

Jungle slots usually give us leaves, growls, and the vague promise that something large is hiding in the bushes. Action Boost Gorilla Gems takes that idea and throws bananas at it. Quite a lot of bananas, in fact. That sounds faintly ridiculous, but the setup works because the whole game is built around what those coloured gems do once they appear. 

We’re dealing with a 5x4 layout, animal symbols, a gorilla wild, and three separate bonus spin modes tied to green, red, and purple Banana Gems. The base game keeps things moving with reveal symbols, while the feature round is where the game starts showing off properly.

We’re dropped into a bright jungle scene with waterfalls, thick greenery, and enough saturated colour to make it clear that subtlety wasn’t invited. The reels sit in the middle while the three coloured bananas hover above, which gives the whole layout a slightly odd but useful visual structure. We can always see which feature each gem is feeding, so the screen stays easy to read. 

Among online slots, jungle themes can blur together after a while, but this one does at least commit to its own gimmick. The animals look sharp, the gorilla has the permanent expression of someone who has had enough of everyone, and the bananas give the game a recognisable identity instead of leaving us with just another generic tropical backdrop.

The lower tier is made up of the royal symbols, while the premium side uses the animal cast. The gorilla wild sits at the top and also works as the key substitution symbol across the base game and the bonus features. 

Special Symbols 

• Gorilla Wild: The gorilla substitutes for all regular paying symbols and also pays on its own. Wilds can appear anywhere on the reels. 
• Random Reveal Symbol: One or more reveal symbols can land on any spin. Every reveal symbol on that spin turns into the same regular paying symbol, and that revealed symbol can also carry a Banana Gem. 
• Banana Gems: Green, red, and purple Banana Gems appear in the base game and are collected above the reels. In the bonus rounds, golden bananas appear instead and award extra effects based on the active mode. 

Random Reveal Symbols 

The reveal mechanic is the main way the base game gets extra movement. When reveal symbols land, all of them show the same regular symbol after the reels stop. That can potentially create fresh line combinations, and it can also uncover Banana Gems that feed one of the three feature tracks above the reels. 

Banana Gems 

Each coloured Banana Gem belongs to its own feature. When one lands, it is collected by the matching banana above the reels. A landed gem can then randomly trigger that banana’s bonus spins feature. There is no scatter symbol here, so the Banana Gems take over that role. 

Green Banana Bonus Spins 

The green banana awards 5 bonus spins. During this round, the reels expand to 6 rows, which increases the active paylines from 20 to 40. Any wild that lands becomes fully stacked and covers all 6 positions on its reel. Every golden banana that appears awards a bonus cash prize. 

Red Banana Bonus Spins 

The red banana awards 10 bonus spins. During this round, every golden banana awards either a jewel or a bonus cash prize. The jewels are tied to four jackpot levels, and each jackpot needs a specific number of collected jewels before it pays: 

Green Jewel 

Collect 3 to award the Mini Jackpot worth 10x. 

Blue Jewel 

Collect 4 to award the Minor Jackpot worth 50x. 

Purple Jewel 

Collect 5 to award the Major Jackpot worth 500x. 

Red Jewel 

Collect 6 to award the Mega Jackpot worth 5000x. 

When a jackpot is awarded, the collected jewel count for that colour resets. 

Purple Banana Bonus Spins 

The purple banana awards 5 bonus spins. Each spin runs with a random win multiplier of 2x, 3x, or 5x. Every golden banana awards either 1 or 2 extra bonus spins or a bonus cash prize. 

We begin on a 5x4 setup with 20 paylines. Wins pay from left to right and must start on the first reel. The structure is straightforward enough on the surface, but the game gets more involved once the reveal symbols and Banana Gems start interacting. The free spin trigger is not handled by a normal scatter, which changes the feel of the base game quite a bit. 

We see the biggest shift in the green mode, where the reel height increases and the number of active paylines doubles. Across online casinos, plenty of games tack on extra features without changing the basic shape of the reels. Here, one of the three feature routes actually changes the layout.

A few recent games from our list make sense alongside this one. 

• Amazing Link Zeus: This one has several feature routes built around special symbols rather than a single simple bonus trigger. 
• Cash Falls Island Bounty: Another strong fit if the appeal is collecting symbols that build toward distinct feature outcomes. 
• Gorilla Kingdom: A title that works as a thematic alternative for anyone who wants more primates and less fruit based decision making. 

Action Boost Gorilla Gems does a good job of separating its feature set into three clear lanes, because a game like this could have turned into a mess very quickly. Instead, we always know what the green, red, and purple paths are doing, and the golden bananas give each bonus mode a reason to feel distinct. 

We wouldn’t call the jungle theme especially original, but the banana structure gives the game its own rhythm. The red mode is the most ambitious, the green mode changes the reel shape, and the purple mode keeps things brisk with extra spins and multipliers.
