In late fall 2021, Maltese provider Relax Gaming released the Cluster Tumble. This slot will be interesting for both beginners and experienced gamblers: it has a huge field and a cluster payout system with unusual bonuses and cascades. The slot pays often and gives a chance to win a huge prize: up to x20000. Due to the cascades and the large size of the field with special symbols in each distribution to play in Cluster Tumble is not boring even in long sessions.
When looking for a good casino with the Cluster Tumble, you can do it yourself. But it takes a lot of time, and there's a chance to make a mistake and end up with scammers who are also adding popular slots from Relax Gaming. It is much easier and safer to go straight to a verified casino. Such can be chosen in our rating: we do not add bad sites.
You can quickly understand the rules and figure out whether you like the Cluster Tumble or not in the demo game. It is free and works without registration.
You don't even need to go anywhere to start it: we've added the demo game to the beginning of the slot description.
From the Casinoz list, you can move on to playing for real money as quickly as possible. There are several casinos that have Cluster Tumble in the list, so you won't have to search for it across different platforms for a long time.
On an 8x8 field, a random number of playable symbols fall in the center area, with empty Stone Blocks surrounding them. The gambler wins if at least 4 identical symbols will cluster together: they will fall on neighboring cells, touching any of the edges (diagonal proximity does not pay out). You can bet from 0.10 to 50 per spin, and win up to x20000. When forming a cluster, the symbols that participated in it are removed, and in their place fall new ones. Empty blocks when cascading do not fall out.
From additional in the slot there are freespins of 2 types (one can be bought or won, the second can only buy), additional multipliers and a couple of bonus features.
There are 4 kinds of symbols that the gambler should know more details about:
Stone Block. An empty block, pays nothing and just occupies a cell.
Scatter. Award freespins if they appear in quantities of 3+ on the field.
Wild. Count towards any winning combination if they appear next to each other. There is a chance that the Wild will have between 1 and 5 lives (the number will appear in the corner of the symbol). In this case, the symbol will remain on the field for that number of spins, even if blocks explode and are removed nearby, or if it gets caught in a payline itself.
Special Stone Block. In each spin, 4 Stone Blocks hide special symbols: W (Wild), lightning (triggers Lighting Win) and fire (triggers Fire Transform). Their location is random each time: maybe they will be next to the playing symbols, or maybe they will be scattered to the corners of the field. To activate them, any winning combination must be placed next to the block.
Several bonus features are available in the slot, working according to the following rules:
Buy Bonus. This is where you can pay and trigger a free spins package.
Lightning Win. Lightning strikes a random number of symbols, transforming them into a sign of the same species. The transformed characters pay even if they don't cluster together.
Fire Transform. A random number of characters are transformed into other characters. This is how new payout combinations and new cascades can form on the field.
Free Spin Multiplier. Only works in free spins. Additional multiplier appears if you break all Stone Block. It increases for each achievement by +x3 (first time x3, then x6, and so on), and remains until the end of the freespin round.
5 free spins will automatically trigger if 3 Scatter symbols fall on the field. Each Scatter will add +1 FS as the pack scrolls. During the round, the Free Spin Multiplier feature is in effect. When all Stone Blocks are destroyed, the gambler will get 3 more spins.
Free spins can also be purchased in Buy Bonus. Available packages of 2 types: simple for x100 of the bet and Volatile Free Spins for x200. The difference is that in expensive FS additional multiplier grows not by x3, but by x6.
The characteristics of the Cluster Tumble make the slot interesting for those who are going to play for money and want to close sessions in the plus:
The standard RTP for regular spins is 96.40%. In freespins, it's a bit higher: 96.48%. And in the purchased Volatile Free Spins, the return will be even better: 96.57%.
The volatility is high: clusters on a large field are often formed. But most payouts remain small (except those issued after a long series of cascades).
It's unrealistic to come up with a strategy for a game that depends entirely on chance. That's exactly how slots work: the developer builds hundreds of thousands of combinations inside them, of which a very small part pays. And when you start the reels randomly chooses one of them, which the player will see. What exactly it will be (with or without a payout, and if with, then what size) - do not guess in any way, and therefore there can be no strategy.
The gambler will have no problems in getting acquainted with the interface: it is simple and without unnecessary elements. On the side of the field (at the top on mobile devices) is only one button Buy Bonus, all other controls are collected at the bottom. In the center there are buttons to start and accelerate the spinning of the reels. Spins can be started manually or set up an automatic game. With autospins, you can stop them manually, or set several different conditions for this. Before you start playing it is advisable to do this:
Check the payout amounts in the table. It opens from the menu on the bottom left.
There you can also see the principle of forming winning clusters.
Play the demo version until you understand the mechanics of Special Stone Block and Wild's lives.
For cash games, lower the bet to 0.10 so that the deposit is enough for the maximum number of spins.
Android or iOS phones and tablets are just as suitable for playing Slot as computers. Thanks to the mobile version, Slot displays correctly on screens of all diagonals. The buttons are comfortable to press: their size has been increased, and they are placed so that both right and left thumbs can reach them from the corners. The design was also redesigned: it was simplified by removing unnecessary things. Thus, only the most important things for the game are left on the screen, and the gadget will not consume all the resources at startup.
Casinoz experts rated the slot as "excellent" on all criteria. The design is unobtrusive and neat, the gameplay is fun and does not get boring even for a long session. In addition, the slot has a good return on the frequency and size of payouts due to a series of cascades.
