Released: 3 May 2021

ELK Studios has given us a ticket to Jellyton, a wild outer planet where objects and inhabitants are vividly coloured, fluffy and behave rather unusual. There, you’ll get familiar with the Cluster Slide slot, a title with sliding reels and dynamic wilds that set the pace in both the base and bonus features. Winning combinations here contribute to a wild metre that can further lead you to various extras such as symbol upgrades, free spins and multiplier wilds. Find out more about the reel mechanics and win potential in our detailed Cluster Slide slot review.

Cluster Slide Slot Online

ELK Studios has been experimenting a lot with their Avalanche mechanics, combining the slot reel dynamics with the authentic gravity forces. The Bompers slot has announced the Gravity reel mechanic, but it seems that the Cluster Slide slot will popularise this engine on a whole another level…or planet if you prefer.
 
Witness the gameplay of the 7x8 tilted grid and watch how symbols upgrade, trigger bonus features and land with hefty multipliers attached to them. Witness the outer space reel experience for a chance to win up to 10,000x your stake in a single spin? Wondering how? Stay with us as we’ll go through all the details of the Cluster Slide slot.  

About Cluster Slide Slot 

Visit ELK’s inhabited planet called Jellyton and meet the furry little creatures on a 7-column, 8-row sized reel set in a slot game called Cluster Slide. Ok, some of those are covered in jelly, others are furry, while all the rest look like those candies we drool over in the candy shops. Yes, it’s a pretty strange but attractive outer world that’s quite friendly when it comes to visitors. To win, you must create a cluster of 5 or more matching symbols on the grid.

Instead of dropping on the reels, new symbols slide on the grid, occupying available positions from right to left. These gravity slides will keep on coming until you form winning clusters on the grid. When the winning sequence stops, a new payout calculation is made, and you’ll get to spin the reels again.

Before you embark on this trip to Jellyton, it’s good to know that you can set up your bets in the range between £0.20 and £100 per spin. Click on the coin icon in the bottom left corner of the screen and choose one out of the 12 different offers.
 
The Cluster Slide slot game can really lead you to a furious reel action with the sliding wins. This way, you’ll trigger various wild symbol effects, multipliers and bonus features that will get you closer to the maximum win set at 10,000x your bet.

Design, Symbols and Graphics

The outer space theme of the Cluster Slide slot is nicely done, giving a bit of cartoonish feel to the design. The uplifting ambient sounds from the background work great for the overall atmosphere. They aren’t intrusive, and you’d definitely want to keep the sound on.
 
On the paytable, you’ll notice 4 lower-value jelly monsters in blue, yellow, green and red, followed by the higher paying purple, green, orange and red furry creatures. They’ll all smile and give you a wink when they form a win. Occasionally, they become hungry and can eat a few same coloured symbols. The highest paying symbol in this collection is the red furry monster with moustaches and crown. If you’re lucky to get 15 of those in a winning cluster, you’ll win 500x your bet.
 
You’ll come across 5 different wilds during gameplay. The regular wild will land in pink or blue square with the letter W on it. This wild will help you form a winning cluster if you lack the symbol you need. All other modifier wilds can randomly land during gameplay, but they’ll show their reel powers only if they are a part of a winning cluster. We’ll go through all Modifier Wilds in our bonus section below.
 
Finally, the B letter is the bonus scatter symbol that triggers the Wild Drops feature, where you’ll receive free spins/drops. During this feature, wilds progress in their size as you spin the reels, landing in 1x1, 2x2 or 3x3 formations. 

RTP, Variance and Payouts for Cluster Slide Slot 

The Cluster Slide slot’s RTP (Return to Player) is 96% which is straight up the industry average. Moreover, the variance tends to be high, so there won’t be frequent wins during gameplay. However, once you trigger a win or cause an avalanche reel reaction, it will be of a higher value.
 
Bigger wins will come from the different wild modifiers and multipliers during bonus games. The maximum win in the Cluster Slide slot is 10,000x the stake. If you want to learn more about other RTP and variance slot models, read our Variance, Volatility and RTP guide. 

Gameplay and Features on Cluster Slide Slot 

The fun part in the Cluster Slide slot starts when you fill the Wild feature bar just above the grid. This bar triggers different wild modifiers that further take you to bonus games and free spins for even more exciting hangouts with the cute candy-like creatures. Let’s see what you’ll come across as you spin the reels and how these bonus features can benefit you.

Feature Wild Generator 

The winning symbols from the clusters contribute to the Feature bar, sitting in the top left corner of the grid. Once you fill the metre, you’ll apply one of the five feature wilds on offer.

  • Big Wild Feature – you’ll get a 2x2 wild symbol;
  • Random Wild – minimum of 2 and maximum of 4 positions on the reels turn wild;
  • Multiplier Wild – you’ll increase a multiplier by 1x;
  • Upgrading Wild– upgrades a symbol into the next higher-paying one;
  • Removing Wild– all symbols from the same type are removed from the grid. 

If you’re lucky to generate all 5 wild features in a spinning round, you’ll apply x5 to the total win multiplier.

Wild Drops

The Wild Drops, or if you prefer, the Free Spins feature, is triggered as soon as you land 3 scatter symbols on the same spin. Your prize is 3 Free Wild drops, where symbols evolve and grow. So, on the first drop, the triggering scatters transform into wilds and add three 1x1 wild symbols to the grid. The second drop adds two 2x2 wilds in size, while the third lands one 3x3 wild on the grid.

Cluster Slide Slot on Mobile 

The Cluster Slide slot by ELK Studios is HTML5 optimised, meaning it works without issues on any mobile device and any operating system. With 56 active symbols on any spin, rest assured that the developer paid great attention to sharpness and quality when playing this game on a smaller screen.

An absolute must-check on this list is the Nitropolis 2 slot.

Notice how ELK is inspired by the animal world, regardless of whether we discuss the real or sci-fi scenarios? Maybe this slot is a great fantasy-themed title, but the maximum win capped at 10,000x your bet is surely real.
 
The Katmandu Gold slot is the fifth titles from the “Gold” series that will take you to the wild and mysterious Nepalese mountains. Along the way, you’ll have a chance to play with avalanches, ice climbers and free drops for an opportunity to win 10,000x your stake.
 
If you can’t get enough of extra-terrestrials and inhabitants from another planet, then the Visitors slot will definitely suit you well. This cartoonish title will acquaint you with the aliens as we know them, triggering different in-game bonus features that might significantly boost your total.
