Big Time Gaming has already revolutionized the online slot industry once with its innovative Megaways concept. The Australian developer isn’t one to rest on its laurels, with its most recent invention, Megaclusters, gaining significant traction on the global online casino scene. The Megaclusters experience certainly isn’t one to miss for gambling fans looking for slots without traditional paylines. Similar to its Megaways engine, Big Time Gaming recently licensed the mechanic for other developers to use. This has spawned a healthy selection of Megaclusters slots, available at countless worldwide casinos. Jump into our comprehensive overview below for the lowdown!

More about megaclusters slots

What Are Megaclusters Slots?

Megaclusters slots don’t take the conventional payline approach to gameplay, using a grid design reminiscent of popular mobile games such as Candy Crush or Bejewelled instead. These games are essentially next-gen continuations of popular cluster pay slot titles, albeit with added multipliers, wilds, and other bonus features

This results in larger payouts on average and the potential for the standard grid to expand in size. Megaclusters slots can vary in volatility, although options such as Cyberslot Megaclusters and Kluster Krystals Megaclusters have significantly high variance. It can take a while to hit winning combinations, but the jackpots make it more than worth it when you do. 

Megaclusters slots typically start off with a 4x4 grid. This can expand to 8x8 or more as you experience winning symbol combinations and bonus features. The expanding reels concept borrows features from BGT’s Megaways engine, but the two game mechanics are fundamentally different. We’ll explain how Megaclusters work in comprehensive detail below.

How Do Megaclusters Work? 

The Megaclusters game mechanic isn’t particularly difficult to understand, especially if you’re familiar with the Megaways concept or grid slots. Big Time Gaming has made it similarly easy to win multiple times off one stake, especially when wild and bonus symbols are involved. 

Megaclusters slots don’t use paylines, with players hitting winning combinations by forming symbol clusters. You will commonly need at least five symbols touching horizontally or vertically to achieve this. The reaction feature kicks in here, causing the winning symbols to explode from the reels. Unlike Megaways slots, where new symbols fall in the vacant spaces, Megaclusters games replace each winning icon with four smaller symbols. This can cause a chain reaction, ultimately causing several wins on the same spin. 

Things get even more exciting in the free spins round, where the grid expands to an initial 8x8. There are no scatter symbols necessary, just hit five reaction wins in a row to trigger this feature. Players can enjoy a maximum 16x16 grid during the free spins bonus round, housing a massive 256 symbols. 

As you can tell, the Megaclusters gameplay is seriously high-octane. We suggest playing in demo mode first so you can get to grips with everything without spending real money coins. Alternatively, use online casino no-deposit promotions to play for free and learn the ropes without worrying about potential losses. 

We’ve listed a step-by-step overview of the Megacluster playing process below to make things clearer: 

  1. The gameplay begins with a 4x4 grid. 
  2. Match at least five symbols in a cluster to score a winning combo. 
  3. Each symbol involved will explode and be replaced by four smaller icons. 
  4. If the new symbols create a winning combination, they disappear from the reels, allowing new icons to fall in their place and potentially generate more wins. This mechanic is commonly called cascading reels or avalanches in other games. 
  5. Five avalanches or reactions in a row generally trigger the free spins feature or other bonuses. 
  6. The grid expands to 8x8 during free spins, potentially hitting a maximum 16x16. There is also a progressive win multiplier to enjoy. Look for the multiplier meter at the top of the screen to check this. 

What Features Do Megaclusters Have?

The Megacluster feature is understandably the most obvious characteristic of these trailblazing slot games, but there are other ways players can increase their winnings. You can find a quick rundown of the main Megaclusters features below: 

  • Reaction: Otherwise known as cascading reels or avalanches, the Megaclusters Reaction feature causes winning symbols to explode, leaving four smaller icons in their place. If the new symbols are involved in wins, they disappear from the reels, allowing new symbols in their place. 
  • Free Spins: Every Megaclusters slot has a free spins round, as this is where the so-called Megaclusters come into play. Players can enjoy at least two free spins whenever they hit five successive reaction wins. This bonus feature takes place on an 8x8 grid, with the symbols getting smaller enough to potentially form a 16x16 arena. As you can imagine, this can cause countless wins! 
  • Multipliers: Megacluster games also have several multiplier levels during the base mode and bonus features. Wild symbols often have progressive multipliers attached, while some games have multiplier meters that offer plenty of large payout opportunities. Additionally, games like Millionaire Rush Megaclusters have various special multiplier options in their Megatrails feature.

Big Time Gaming has licensed this innovative mechanic to other providers like Blueprint Gaming, Relax Gaming, and Playtech, so this is by no means an exhaustive list of Megaclusters features. Each developer can put its own spin on the system, so there are countless bonuses available at slot sites worldwide. Here is a taster: 

  • Roaming Wilds 
  • Sticky Wilds 
  • Low-Value Symbols Removed 
  • Transforming Symbols 
  • Mega Wilds 
  • Multiplier Wilds

Triggering the Bonus on a Megaclusters Slot 

Megaclusters slots generally come with several bonus features, but the main one is almost always the free spins round. You can enjoy the innovative mechanic to its fullest here, as games like Star Clusters Megaclusters offer 256 symbol positions on the grid allowing frequent cluster wins. 

Essentially, triggering the free spins bonus round on a Megaclusters slot boils down to getting five successive cluster wins in a row. Things differ from game to game as developers find new ways to innovate on Big Time Gaming’s exhilarating new game system.

List of Best Megaclusters Slots 2022

The Megaclusters concept is still relatively new, and there are fewer slots than Big Time Gaming’s flagship Megaways system. Fortunately, all Megaclusters games are impeccably designed, showcasing impeccable visuals, themes, and gameplay. Online casinos around the world stock these titles, so you can enjoy a reel-spinning adventure wherever you are. 

We wouldn’t blame you for feeling slightly overwhelmed if Megaclusters is a new concept. Choosing somewhere to start can be challenging. Check out our expert picks below:

#1: Star Cluster Megaclusters 

Star Cluster Megaclusters was the first slot to use Big Time Gaming's new game engine. Released in 2020, it features a huge 23,960x maximum win alongside 96.54% RTP and medium-to-high volatility. Winning symbols split into smaller clusters in this rollercoaster of a slot, generating up to 256 positions. Star Cluster Megaclusters ensured BGT’s novel concept started off with a bang, and it’s been a modern classic ever since. 

The slot also has two separate wild symbols, with the Gold Wild powering a progressive multiplier meter on the top of the screen. Star Cluster Megaclusters is available on all devices due to its HTML5 software design. The grid slot holds up surprisingly well on smaller smartphone screens, as the graphics are still clear enough to keep track of. 

#2: Millionaire Rush Megaclusters 

Millionaire Rush Megaclusters could genuinely be one of the most powerful online slots of all time. Its Megaclusters engine is just the tip of the iceberg here, as Big Time Gaming has packed this game with an extraordinary 12 potential bonus options. The Megatrail feature randomized a dozen distinct special bonuses, including symbol explosions, mega wilds, transforming symbols, symbol duplication, and more. 

Elsewhere, the graphics and attention to detail recreating Who Wants To Be A Millionaire are top-notch. With nods like the 50/50 bonus in the gameplay, Millionaire Rush Megaclusters really evokes the legendary gameshow’s spirit. Maximum wins can hit as high as 55,060x, and the RTP is above average at 96.44%

#3: Diamond Fruits Megaclusters 

Diamond Fruits Megaclusters doesn’t have the same huge maximum win as other games, with the jackpot limited to 6,650x. It will be underwhelming to large jackpot hunters, but more cautious players will love it. Big Time Gaming guarantees a high hit frequency during Diamond Fruits Megaclusters, especially in the free spins bonus, where players are treated to the same unlimited multiplier in Bonanza. 

This isn’t the only unique thing about Diamond Fruits Megaclusters, as the developer has also debuted stunning 3D reels. It modernizes the classic slot machine theme perfectly, and we’d be surprised not to see this graphics strategy in the future. RTP is set at 96.23%, and this game will suit all slot wagering preferences with the 0.20-75.00 min and max bet amount. 

#4: Kluster Krystals Megaclusters 

Kluster Krystals Megaclusters was one of the first titles created by a different developer, with Relax Gaming taking the reins from Big Time Gaming. It has more than done the Megaclusters engine justice, with a high 96.49% RTP and several creative bonus features. Relax Gaming is known for its fun and forward-thinking approach to slots, and Kluster Krystals Megaclusters is no different. 

The Symbol Upgrade feature is what really sets this game apart from other titles. You’ll notice each of the symbols can appear as single, double, triple, or quad gems. These upgrade once they touch a winning cluster, increasing the potential payout. Kluster Krystals Megaclusters also has three randomly triggered bonus features that upgrade or remove symbols on the reels. 

#5: Cyberslot Megaclusters 

Take a journey to the edge of the galaxy with Cyberslot Megaclusters, a futuristic Big Time Gaming slot featuring 96.54% and a sizable 23,960x maximum win. The action starts off on a smaller 3x3 grid than other Megaclusters games, but nine cluster icons replace each winning symbol. This can open up to 321 positions, more than the likes of Star Cluster Megaclusters. 

Big Time Gaming has thrown in a lucrative roaming wild alongside the standard Reactions feature, with at least one in play on each spin. The special symbol can assist winning reactions and leaves behind a nine-symbol cluster of mini-symbols each time it moves positions. You must hope for 12 reaction wins in a row to reach the Cyberslot Megaclusters free spins round, where six free spins and 321 potential symbols. Get lucky here, and the 23,960x maximum win is yours.

Who Is Big Time Gaming?

Big Time Gaming has done more than most to evolve the online slot industry, especially over the last decade, where big names such as NetEnt and Microgaming struggled to invent anything truly groundbreaking. The Australian company started out in 2011, finding fame with Bonanza in 2016. 

Since then, the developer has become one of the most important parts of the modern slots scene, licensing its Megaways and Megaclusters concepts to several other game providers like NetEnt, Relax Gaming, and Pragmatic Play. Big Time Gaming has ensured more excitement for all worldwide slots players in the process. 

It’s not just the creative game engines and special features that make Big Time Gaming slots so good either, as the provider is passionate about mobile slots, smooth gameplay, and HD visuals. Check some of the games below for the top slots to play: 

  • Bonanza 
  • Star Cluster Megaclusters 
  • Millionaire Rush Megaclusters
  • Cyberslot Megaclusters 
  • White Rabbit Megaways 
  • Extra Chili Megaways

Pros & Cons of Megaclusters Slots

It’s difficult to beat the sheer excitement of playing Megaclusters slots, especially when the Reactions feature kicks in. The action can get more fast-paced than Megaways games, with winning symbol combinations coming thick and fast on the enlarged slot grid. While this is a positive for many players, it can also be a bit overwhelming for beginners, so bear this in mind. 

Playing Megaclusters games also involves a fair amount of risk compared to simpler slots. Most games have higher variance, which is perfect for high rollers but can also quickly drain your bankroll. On the other hand, there is massive jackpot potential, so patience and careful betting can pay off handsomely. Here are the main Megaclusters pros and cons:

Megaclusters vs. Megaways Slots

While there are similarities between Megaclusters and Megaways slots, they are two distinctive gameplay engines. Megaways slots typically have six reels, with a random modifier changing the number of symbols from one to seven on each. With the full number of Megaways open (7 x 7 x 7 x 7 x 7 x 7), players can enjoy up to 117,649 ways to win. 

Megaclusters are different. These games operate on a cluster pay mechanic using a grid slot design, eliminating the need for reels. Each winning symbol can split into four smaller symbols, a process that can be repeated until it forms a 16x16 grid. At its fullest, that’s 256 potential positions. 

Megaclusters and Megaways slots are similar in their bonus features, especially the base mode cascading reels or Reactions wins. Winning symbol combinations explode from the grid, allowing new ones to fall into place. Generally speaking, you can enjoy a progressive multiplier as this happens. 

Final Thoughts on Megaclusters Slots

Megaclusters slots certainly aren’t games to miss. Titles like Star Cluster Megaclusters and Millionaire Rush Megaclusters are some of the most entertaining iGaming options available right now, supercharging the online slot experience to a whole new level. 

Big Time Gaming and other developers have done extremely well in designing these games. It wouldn't have been possible to create such smooth gameplay and HD graphics a few years ago, so Megaclusters titles are solid proof of how the industry has advanced. 

Despite the high win potentially, above-average RTP, and exhilarating gameplay, there are a few things you should be wary of regarding Megaclusters slots. They can be far too complex and confusing for first-time players, while others may find the symbols too small, especially on smartphone screens. 

Regardless, we absolutely love Megaclusters games! They are definitely worth trying, and we’re not sure you’ll be able to play another type of slot again after trying them.
