How to Play Cluster Tumble Slot

Set your bets and let’s try and find a way through this ancient temple filled with blockades that you need to clear.

  • Fast Forward button will speed up the reels spinning motions.

  • Autoplay will help you set the number of automated spins without any interruptions once you get tired of spinning the reels manually.

Slot Features

You will start out with a small playing field that is surrounded with the stone blocks, and creating win combos next to those blocks will break and remove them opening more of the active playing field positions. These blocks can hide special symbols that you will see etched in the stone, and once those blocks break, the modifiers will get activated.

Special Stone Blocks

Special stone blocks include Wilds, Lightning and Fire. Wild symbol will sub in for all the regular paying symbols and create more win combos. Lightning Win, when activated, will replace this symbol block with the target regular symbol that will be followed by a cascade of all the regular same kind symbols to create a win. Fire Block will get replaced by a target symbol as well, which will be followed by a cascade of between 1-2 symbol kinds that will get transformed into the same kind as the target symbol to create more wins.

Free Spins

If you either land 3 Scatters on the active playing field or manage to clear all the blocks from the board, you will trigger the Free Spins round which will award you 5 spins. If you do not want to wait for regular triggers, you can buy your way into the feature and choose regular or highly volatile round which will also award you 5 spins to kick it off.

If you clear the entire board during the round you will win additional 3 spins and a win multiplier will increase by x3, and these will grow in progressive manner – x3 on first clearance, x6 on second, x9 on third and so on. The win multipliers will get applied as soon as they are awarded and will be persistent through the round. In addition, at least 1 Scatter landing during the round will award one more spin each time it happens.

Cluster Tumble is a cluster slot from Relax Gaming that was launched late last year. I was quite interested in trying this game out for various reasons. First of all, I quite like Relax Gaming games and especially their tumble games (like Temple Tumble, TNT Tumble etc) so I was curious to see what this game has to offer. Also, quite early on, someone had a maximum win on this game, so of course that piqued my interest even more.

The game itself has a cluster pays mechanic, but in this case you need to have at least 4 same symbols in adjacent positions. And on each spin, you start with a different cluster, and once you get winning combinations, the grid expands. If you manage to clear the whole grid, you'll trigger the bonus round- or alternatively you can get the free spins by 3 scatter symbols. What I like about this game is that it has several different features. As usual, there's a wild symbol and each wild can have a different number on it- meaning how long it will stay on the screen. For example, if the wild has 2 on it, it means it will potentially contribute to 3 wins on that spin. I haven't seen it much before so that was a nice surprise. Also, there are Lightning blocks and Fire blocks- if you unlock them, they ultimately change symbols into matching ones. It can definitely help getting decent base game wins. My best win from the base game was about 50x because of the wilds and fire transform feature.

As I mentioned before, there's also a free spins bonus- I have a mixed relationship with it. I think it has a lot of winning potential, which I like, but on the other hand, it's super volatile. You only get 5 free spins and you start with no multiplier. Then, if you clear the grid, you get 3 extra spins and the multiplier increases. So far I've been able to get to the 6x multiplier once, and unfortunately it resulted in many dead spins. But I do like the fact that the multiplier can increase, but clearing the grid in this game seems very difficult. Then there's also a super bonus, which you can buy for 200x your bet- it works the same way as regular free spins, but the multipliers increase for double the amount. I've bought the super bonus twice and both times didn't even win my bonus cost back, so I wouldn't recommend buying it.

Overall I do like this game simply because it has a cluster mechanic and the different blocks which can help getting decent base game wins. As for the free spins, so far I haven't had any wins over 200x bet on it and they feel very volatile. So while I do know this game has a great winning potential, I'm not playing it much these days because of the high variance.

Relax gaming has introduced a lot of clustered slots, taking place on 7x7, 8x8 grids and they are extremely highly volatile with winning potential between 20 000 – 50 000 your total bet which is extremely huge. And the best part about it, you actually do see that huge max wins once a week on one of their releases.

Cluster tumble is another remake of the popular Temple Tumble from Relax, which was one of the first games they introduced. The set of reels takes place in some temple at the back. You will find crystals and ancient faces, scarabs, and many more. You need to cluster 5 of a kind to generate a win.

The game has a lot of feature triggers:

Wild are created by certain stone blockers

Lighting Win – The Block transforms into a specific symbol, and all symbols of its kind pay as a scatter win.

Fire Transform turns the block into a normal symbol with and with the following cascades, the specific random symbol is turned into the same symbol.

Landing 3 scatters anywhere will trigger the free spins feature. This game does not get triggered by clearing the grid, however clearing the grid during free spins, will increase a sticky multiplier. You are awarded 6 spins and if you clear the grid extra spins are awarded.

The multiplier is unlimited, and you can win unlimited spins as well. However, the cap is 20 000x your total bet.

As much as I like this slot and relaxed gaming releases. I prefer Temple Tumble over this slot. The base game does not play well, you feel like you losing your balance too quickly. It makes me feel I need to buy the bonus in this game and I prefer the old-school slotting way.

Even when I buy bonuses in Relax Gaming slots, my luck just has never been there. Always at a disadvantage. I would suggest just buying the feature and hoping for the big win.
