Cluster Tumble Slot Overview

Cluster Tumble is a new casino slot from Relax Gaming, where we get to experience the fifth edition of their Tumble series. We have previously taken part in slots like Temple Tumble Megaways, where we travelled to the deep jungles of Cambodia in search of big hidden treasures. This time we follow the brave female explorer in her quest to rescue her kidnapped boyfriend, where during this rescue mission up amongst the Himalayan wilderness we may even manage to scoop up some big wins. It is a slot with 8X8 reel setup that we get to enjoy here, where with the help of the wilds and power up blocks, filled with great features, you can scoop up wins of up to 20000X the bet. Let's find out what you can expect to see during the spins.

Base game

Cluster Tumble is a video slot from Relax Gaming that has 8 reels and 8 rows. You create a winning cluster by landing 4 or more of the same symbol types in a cluster. You can choose between making a Min.bet of 0.10 and a Max.bet of 50. The game's RTP is 96.40% during the normal mode, but by using the Bonus Buy feature, the RTP can be increased to 96.57%. You will on average get one hit every five spins, since there is a hit frequency of 20.29%. Cluster Tumble has a high volatility, where the lucky player can win up to 20000X the bet.

Within this gaming adventure up among the Himalayan mountains, we have a bunch of great features to help us in our quest for big wins. The features are Wild Symbol, Tumble, Free Spins, Special Stone Blocks and Bonus Buy.

Cluster Tumble Slot Information

The game design is Himalayan themed, where we join the brave female explorer in her search for her kidnapped boyfriend. It's a slot where Relax Gaming has added short movie sequences that put you in a good mood for the spins. At the intro you see the explorer climbing up a mountain and then being met by a gigantic gate, where it then transitions to the slot setup. You can play Cluster Tumble on all the device’s notepads, desktops and mobiles. You create a winning cluster by landing 4 or more of the same symbol types in a cluster with adjacent symbols.

The lower paying symbols are gems in the colors blue, green and red. Landing 40 or more of the same symbol type pays 50X the bet. The higher paying symbols are a mask, a scarab and a mountain lion. Landing 40 or more of the same symbol type pays between 100X to 2000X the bet. The game's wild symbol consists of a red W, where it lands with an associated life that can show up to 5. The golden symbol with a skull on top, is the game's scatter symbol. During the spins you will also be able to land special stone blocks that show a W, a lightning bolt or a flame. There are also stone blocks that only block and don't add anything extra during the spins except blocking wins. Let's find out what the features do.

Cluster Tumble Slot Features

What is the max win in the slot Cluster Tumble?

You can win up to 20000X the bet.

What features are available in the slot Cluster Tumble?

The features are Wild Symbol, Tumble, Free Spins, Special Stone Blocks and Bonus Buy.

Free Spins feature

Wild Symbol

The game's wild symbol helps to create more winning combinations by substituting for other symbols. When the wild lands, it can have up to 5 lives which then gradually decrease as it participates in wins.

Tumble

When you spin the reels and create a winning cluster, the Tumble feature is activated. Then all symbols that were part of the winning combination will disappear from the reels. Then new symbols will fall down to cover the empty positions. Any adjacent stone blocks will be destroyed, making it possible to land more symbols on the reels.

Free Spins

If you manage to remove all stone blocks from the reels or land 3 scatter symbols, the Free Spins feature is activated. You will be welcomed with 5 free spins, and you can also get extra free spins by clearing all the reels. You will then receive 3 extra free spins and you will also receive a win multiplier of 3X. Each time you then clear the reels, the win multiplier will gradually increase by 3X, with the current win multiplier being applied to any wins created and staying during the bonus feature. Each time you land a scatter symbol, you will receive 1 extra spin.

Fire Transform - Free Spins feature

Special Stone Blocks

There are different stone blocks placed on the reels within the Free Spins feature and when they are adjacent to a win that is created, you get to enjoy their respective features. They are Wild, Lightning Win and Fire Transform and they do the following:

Wild = This helps to create more winning combinations by substituting for all normal symbols.

Lightning Win = When this is activated, it will be assigned a random symbol from the normal symbols. Once the Tumble feature has been activated and awarded any wins, you will be able to take advantage of the Lightning Win feature. Then all symbols on the reels showing this randomly assigned symbol including wild symbols will create a win. So, it doesn't matter where these symbols are placed on the reels for them to create a win.

Fire Transform = When this is activated, it will assign a random symbol from the normal symbols. In the subsequent tumble that occurs, 1 to 2 symbol types will be transformed into this randomly selected symbol type.

Bonus Buy

If you want to take advantage of the Free Spins feature right away, you can use the Bonus Buy feature. You can then choose between 2 different options which are as follows:

100X = You trigger the Free Spins feature and receive 5 free spins. The RTP is 96.48% within this Bonus Buy.

200X = You start the Free Spins feature and receive 5 free spins. The difference here is that the win multiplier increases twice as fast as before, i.e., 6X, 12X, 18X etc.etc. The RTP is 96.57% within through this Bonus Buy.

Cluster Tumble Slot Conclusion

Here we take part in another exciting gaming adventure within Relax Gaming's Tumble series. This time they have certainly staged the location we find ourselves in very well, where you are greeted with a short movie sequence at the start. There we see the female explorer climbing up a mountain in search of her missing boyfriend, where she then stands in front of a gigantic gate. They manage to create a good atmosphere with these intros and also with the help of the subsequent design and music that plays. The music along with the effects from the blocks falling down, gives an extra depth to the spins being made. Once again, this is a slot that has been created, where the Tumble feature is the focus. There is a large reel setup of 8X8, but many of these positions are blocked by stone blocks, but during the spins you can manage to blast these away. Unlike the more classic cluster pays where 5 or more adjacent symbols create a win, you create wins by landing only 4 here. This results in wins being created more frequently and once a Tumble is activated, it can last for an extended period of time.

By landing 3 or more scatter symbols or removing all symbols, the Free Spins feature is activated. This is where you have the opportunity to win really big, whereby removing all symbols you receive win multipliers that increase by 3X each time this happens. To make it all much more festive and facilitate the hunt for the big wins, you can take advantage of various special stone blocks, where wilds, fire transform and lightning win are available to be activated. These intertwine in a very elegant way with the Tumble feature, and one is fascinated many times by how long the Tumbles can last and the big wins they can generate.

We've been following along with this Tumble series for a while and one thing that has been constantly recurring is Relax Gaming's generosity when it comes to the potential maximum win. Within this slot you can take part in up to 20000X the bet, which makes everything significantly more festive. They have experimented with different solutions within this series, where the cluster pays mechanic really feels like the optimal solution to this structure. It's an RTP that is higher than average, where it also increases further if you take advantage of the Bonus Buy feature. You can tell that they have created more slots in this genre in the past, where all the components within this slot feel well calibrated and polished. If you like slots with Tumble features, then within this slot you are certainly up for a treat.

Cluster Tumble is a slot where we are up among the high mountains of the Himalayas and with the help of the wilds and power up blocks, we can take part in gigantic wins.
