I dove into the Keep Em Cool slot after scoping out the best slot sites that feature this studio's work. Amidst a backdrop of fruits, sandy beaches, cocktails, and an adorable piggy, slot games have never felt more inviting. Hacksaw Gaming impressively merges familiar themes with stunning visuals and a comic-style soundtrack. Unlike traditional slots, this one boasts a 5x5 grid that forgoes standard paylines for a cluster pays mechanic, a refreshing twist. With medium volatility and an enticing RTP of 96.19%, it strikes a balance between risk and reward. Plus, the chance to trigger multiple bonus features adds an extra layer of excitement.

Graphics, Music, and Sound Effects

Once you see the Keep Em Cool slot for the first time, you will agree that this release provides a unique visual experience. We are not talking only about the polished symbols in vibrant colours on the semi-transparent matrix with a wooden frame.

There’s also the backdrop that will make you think about exotic summer destinations. The background image depicts a coconut palm tree on a beautiful beach and a turquoise-coloured sea (or ocean). On top of that, we have a cute piggy with beach equipment, including a pink inflatable.

The music is equally enjoyable. You can listen to a vibrant piece of Pacific-sounding instrumental music. The sound effects come into play after hitting winning combos.

Key Features

For the best Keep Em Cool slot review, we knew that we had to analyse the crucial features of this game in detail. This was not a problem for us because it turned out that this title was pretty playable.

We followed the pattern of all our slot game reviews at OLBG to ensure you get the information you need to form an opinion about this game. In addition to describing the slot’s theme, reels, and paylines, you can read about its stake range, bonus features, RTP, and other essential things.

Now let’s unveil what we found in the Keep Em Cool slot game.

Theme – Fruit

There’s no doubt that the central theme of the Keep Em Cool online slot is fruits. Even the title suggests that the things that should be kept cool are the fruits. Still, this is not the only thing you’ll find in its story.

For example, this release will help you blend the fruits and get virtual cocktails. Also, it includes a funny piggy character waiting for fresh fruits at the tropical beach. So, we can say that the Keep Em Cool slot has an exotic version of the classic fruit theme.

Every player should spend some time checking the payout table if they want to get details about this slot’s story. First, we have seven fruits acting as basic symbols: Strawberries, Pitayas, Plums, Cherries, Oranges, Bananas, and Green Apples.

After that, we have the icons with exceptional properties: the Cocktail Glass, Blender, and Picnic Baskets.


The Keep Em Cool online slot has 5 reels, the most common number of reels in this casino game. On the other hand, it has a slightly higher number of rows per reel – 5. The 5x5 gameboard usually suggests an unconventional paying mechanic.


As suggested in the previous section, the Keep Em Cool slot has an atypical paying system that doesn’t involve paylines or winning ways. We have a game with a cluster pays mechanic. Simply put, you get rewarded when you land five or more identical basic symbols on adjacent positions (in clusters).


Some providers hide the information about their games’ RTP, and most will highlight the percentage. Hacksaw Gaming is a rare provider that shares the Return to Player percentage and explains how they got it.

According to Hacksaw Gaming, the Keep Em Cool RTP is 96.19%. This percentage is a result of a simulation with 10 billion spins. So, you can tell that it’s a theoretical value, but it’s still a solid indicator of what you can get from this title.

On the other hand, the online casinos where you can play this game are not bound by this percentage, meaning they can use another RTP. If you want to save time, check our list of UK-friendly online casinos and the specific RTP of Keep Em Cool.

Players should consider this percentage and a few other factors like cashier options, game selection, and welcome bonuses and deals when evaluating a casino site. You can read our expert casino reviews for this info.

Stake Range

Almost thirty betting options are available to players at the Keep Em Cool online slot. The minimum stake you can wager here is £0.1. Of course, there’s also a maximum stake - £100 per round.

Max Win

You should expect an average maximum win cap in this slot game. More precisely, the limit is 5,000x for the total bet.

Frozen Symbols

Every basic symbol can appear in three states: unfrozen, half-frozen, and fully frozen. When you hit a winning pattern, the unfrozen icons contributing to the win will be eliminated. Once all winning combos are awarded, all unfrozen icons on the matrix will be destroyed regardless of their contribution.

As expected, the half-frozen and fully-frozen icons will stay even when participating in winning combinations. However, the fully frozen will become half-frozen, and the latter turn into unfrozen. New icons take the positions of removed symbols. These transformations and cascades happen until players run out of new wins.

Cocktail Glass/Blender Symbols

Next on the list of special features, we have the ones associated with the Cocktail Glass and Blender symbols which are actually Scatter icons.

First, when players hit a winning pattern when the Cocktail Glass is available on the matrix, the winning combination icons will be re-frozen to fully frozen. You will notice that the Cocktail Glasses carry numbers indicating the number of re-freezes left (up to 5).

Regarding Blender Scatter icons, every time you get one, it will be activated to select one kind of icon to absorb. So, all instances of that icon are absorbed, and new symbols will come to their positions. This will keep occurring until you are left without symbols of that kind.

Once the feature is over, you will get a reward matching the cluster of the absorbed number of icons.

Sunset Picnic Bonus Game

The third type of Scatters is the Picnic Basket. Whenever you get one on the reels, it will be collected. When you land three Picnic Baskets in one turn, the Sunset Picnic Bonus Game will be launched.

Basically, you should expect free spins (9 to 15). More Cocktail Glasses and Blenders tend to appear during this round. Also, hitting extra Picnic Baskets during this special feature provides 2 to 5 additional free spins.


There’s no direct jackpot or progressive jackpot in this game. The highest amount you can in the Keep Em Cool slot can be worth 5,000 times your stake.

Play Experience & First Impressions

Since there are many fruit-themed slots out there, it’s fair to ask what makes the Keep Em Cool online slot different. Thanks to my 100-spin test, I found a few answers to this question.

Let me start by noting that this release has a unique vibe. It’s not a classic fruit-themed title because the story takes place on a tropical island, on a sandy beach. Also, I was pretty happy with the artwork, which included original shiny visual elements. This was especially true for the colourful splashes after cascades.

The 100-spin test I took was fun; there’s no doubt about it. The wins occurred frequently, but I wish they were bigger. The biggest win was worth 10.4 times my stake. Also, I had fun with the bonus features. Still, the ones with the blender and cocktail glasses are more like reel modifiers giving players more chances of winning than proper bonuses.

So, I didn’t start a round of free spins even though I once collected two picnic baskets. Maybe that’s why the final RTP of my test session was below 50%, which I can’t say is great.

Spinning the reels at the Keep Em Cool slot was fun, but ultimately I achieved small wins and no luck with the free spins, the game’s main bonus feature.

100 Spin Test

100 spins is not a Real Test

We give every slot a 100 spin test to see just what it can do, or not as the case can often be - 100 spins is no reflection of the likelihood of any other 100-spin session, as RTP's are set over many millions and probably billions of spins. So this 100 spin test is just for entertainment and insight purposes

Expert Verdict

With an attractive story involving more than fresh (and frozen) fruits, impressive visual elements, and pleasant music, the Keep Em Cool slot by Hacksaw Gaming lures you into trying it.

This game has a 5x5 grid and features the so-called cluster pays mechanic. You should expect a medium-volatility game that balances the size and frequency of winning patterns. It also has an RTP of 96.19%. Personally, I didn’t reach that Return to Player percentage (I had 43.6%) in my 100-spin test, but to be fair, Hacksaw Gaming got that RTP after 10 billion simulated spins.

One of the best parts of the Keep Em Cool online slot is the bonuses like the free spins, symbol transformation, cascading wins, and a few other things. When you wager the pros and cons of playing this game, you will see that it deserves a try.
