What Is Star Clusters Megapays™ Slot?

Star Clusters Megapays™ is a brand-new video slot in Big Time Gaming’s portfolio, set to be launched officially on the 30th of March 2022. It can be considered a sister slot to Star Clusters Megaclusters™, as the same general layout, design and theme are kept.

However, what differs significantly is the rewards system – this release will be part of Big Time Gaming’s progressive jackpot network, alongside other popular Megapays™ slots, such as Bonanza Megapays™ and Who Wants to be a Millionaire Megapays™.

Players can not only trigger 4 progressive jackpots, but can also enjoy an array of bonus features in the new Star Clusters Megapays™, including multiplier wilds and free spins!

So, will this game take us to the brightest stars in the galaxy? Let’s find out together in this Star Clusters Megapays™ slot review!

Star Clusters Megapays™ Bonus Features

Star Clusters Megapays™ Bonus Features

Star Clusters Megapays™ is a truly revolutionary game, as it brings us the best of both worlds when it comes to Big Time Gaming mechanics – the Megaclusters™ and Megapays™ engines seem to make a fantastic team!

The slot follows a 4×4 grid structure, with 16 symbols by default, which can then get divided by four, reaching a maximum number of 64 symbols in the base game. We can instantly note the comeback of win reactions, the Cluster Pays system and the Gold Wild multiplier.

  • Win Reactions

Because there are no scatter symbols or usual paylines, the win reactions (also called reactive symbols or cascading reels) are the key to unlocking the game’s maximum potential. During the base game, this feature gets triggered by matching clusters of 5 symbols.

A chain reaction ensues and the symbols involved explode, get removed and replaced by new ones. Each individual symbol involved in a winning combination gets divided into 4 smaller ones that fall into the vacant spaces. The motion continues until no more winning clusters are formed.

  • Gold Wild Multiplier

Star Clusters Megapays™ has two types of wild symbols: a rainbow star and a golden star, both of which substitute all other regular symbols. However, the gold wild also raises your odds of winning. When you open the game window, atop of the main reels, you can see the starting multiplier value set at 1x.

When a gold wild symbol substitutes to help you form a winning combination, the value of the multiplier increases by +1.

  • Free Spins

Traditionally, to trigger free spins, you would need a set number of scatter symbols in a particular order. But since Big Time Gaming always likes to do things differently, that is not the case at all with Star Clusters Megapays™.

Instead, you need at least 5 chain reactions to get rewarded with 2 free spins, with an extra spin credited for each reaction after. When the round begins, the game configuration also changes into an 8×8 grid. The more lucky combinations you get, the more each icon can split into four smaller ones, creating a maximum of 256 symbols, thanks to the Megaclusters™ mechanic.

  • Megapays™ Feature

Every base game spin can randomly trigger the Megapays™ feature and reward you with one of the 4 progressive jackpots. Once the feature is triggered, a regular icon will be revealed as a Megapays™ symbol – this can be one of the playing cards: either the Ace, King, Queen, Jack, 9 or 10.

If one or more symbols land, you will receive a respin, however, you need 4 or more to win one of the four jackpots. Your progress will constantly be monitored using a Megapays™ ladder – the more symbols you collect, the higher up the ladder you climb.

The jackpot values are displayed on the left side of the screen at all times and will grow with each player contribution. Each jackpot has a minimum seed value and a set number of symbols needed to trigger:

  • Mini Jackpot – seeded at €100, triggered by 4-7 Megapays™ symbols
  • Minor Jackpot – seeded at €1500, triggered by 8-12 Megapays™ symbols
  • Major Jackpot – seeded at €20 000, triggered by 12-14 Megapays™ symbols
  • Mega Jackpot – seeded at €300 000, triggered by 15 Megapays™ symbols

It’s also essential to note that 9.44% of the total RTP goes towards funding the Megapays™ jackpots. That means a fixed percentage of the player’s bets will be taken – 1.5% for the Mini jackpot, 1.3% for the Minor jackpot, 1.2% for Major and 1.1% for Mega.

Star Clusters Megapays™ RTP, Volatility & Win Potential

Star Clusters Megapays™ slot features an RTP score of 96.27%, which is in line with most Big Time Gaming releases. However, do keep in mind that it has a very high volatility/variance level in theory, offering big-size wins, though with a lower frequency.

The maximum win at Star Clusters Megapays™ is 27,050x your stake, without counting the Megapays™ progressive jackpots.

Star Clusters Megapays™ Stakes & Betting Range

For this launch, Big Time Gaming opted to keep the betting options within the median range, catering to the needs of most casual and passionate players. You can try your luck with a low stake of just €0.20 per spin, whilst the higher end of the betting range is €20.

Theme, Slot Design & User Experience

Star Clusters Megapays™ shares an abundance of thematic similarities with the previous Star Clusters Megaclusters™ from the developer’s catalogue. Once again, we are greeted by an electronic, fast-paced soundtrack that is perfectly in tune with the dynamic action on the reels.

The symbol divisions and explosions are accompanied by superb animations, making this title one of the most visually-appealing ones, particularly on a smaller device.

On the top, players can see the value of the multiplier separated from the main reels, whilst the bottom displays the current number of Megaclusters™.

One significant change is the addition of a live counter for the 4 progressive jackpots displayed on the left side, giving players even more of an incentive to keep spinning!

BTG specified that there is no limit to how much the jackpots can grow, and all of them are denominated in euro currency.

Paytable & Special Symbols

  • Purple, red, blue, green gems – pay up to 50x your stake for clusters of 25+ symbols
  • Orange gem – pays up to 20x your stake for clusters of 25+ symbols
  • Yellow and turquoise gems – pay up to 10x your stake for clusters of 25+ symbols
  • Rainbow star – wild symbol, substitute all other symbols
  • Gold wild – the game’s second wild symbol, activates a progressive win multiplier

Star Clusters Megapays™ Slot Demo & Mobile Play

If you want to play Star Clusters Megapays™ in demo version, feel free to use the launcher on our page so you can learn the ropes, risk-free!

The game uses HTML5 technology and is optimised to run on various devices (laptops, tablets, smartphones). It is also compatible with all modern operating systems – Windows, Android and iOS. Because of the slot’s unique design and high-speed reel action, it’s fantastic for mobile play as well, particularly if you set your device to landscape orientation.

How to Play Star Clusters Megapays™

Australian developer Big Time Gaming is a mastermind of complicated, yet highly rewarding mechanics, such as the iconic Megaways™ slots engine!

That is why, when you first open the slot window, you might be confused by the atypical layout and lack of traditional paylines. Fret not, we’re here to explain how it all works in the easiest terms possible.

The standard layout is a grid with 4 rows and 4 columns, present in the base game. During free spins, the configuration changes to 8 rows and 8 columns.

Instead of paylines, you form winning combinations through clusters of identical symbols horizontally or vertically. Then, every winning symbol will get divided into 4 smaller ones.

A cluster is made up of a minimum of 5 symbols, but you can form even bigger ones with more than 25 icons. On the right side of the game window, you will see the “stake” option, accompanied by two left and right arrow buttons, so you can easily set your desired bets.

The game also provides an Autoplay option if you want to let the game run on its own for 5, 10, 25, 50 or 100 rounds – however, be advised that it may not be available in certain jurisdictions.

Loss limits of up to 140 credits can be set, and the same goes for win limits of up to 1,400 credits.

Star Clusters Megapays™ Pros & Cons

Are you in for an explosive cluster of fun or are you better off choosing an alternative title? Let’s break down the main positives and negatives:


  • 4 progressive jackpots
  • Symbol divisions
  • Gorgeous visuals and design
  • Fast-paced gameplay
  • Free spins with unlimited multiplier
  • Cluster pays mechanic


  • Super high volatility
  • Theme is not very original

Star Clusters Megapays™ Slot Review Verdict

Star Clusters Megapays™ uses a very generic casino theme based on lucky jewels, first popularised by NetEnt’s Starburst. However, the real strength of this title lies in its features. Big Time Gaming took a tried-and-tested recipe further, with symbol explosions and divisions, cascading reels, cluster pays, free spins and 4 progressive jackpots.

Because it’s so jam-packed with features, there is no dull moment to be had in the base game or the free spins rounds. As such, Star Clusters Megapays™ is not just a worthy spin-off to Star Clusters Megaclusters™, but a great standalone title. We presume it will appeal the most to fans of high-speed slots – so long as they’re not too deterred by that explosive volatility!

Other Popular Megaways™ Slots


Megapays™ is the name of Big Time Gaming’s progressive jackpot network, which includes several popular online slots, such as Bonanza Megapays™ or Who Wants To Be a Millionaire Megapays™. All slots included in the network will allow you to trigger the Megapays™ feature and win one of four progressive jackpots.
As opposed to other software developers, starting March 2022, Big Time Gaming opted to release its games in a single RTP version – same will apply to Star Clusters Megapays™. Irrespective of the online casino you choose, you’ll play with the same RTP score of 96.27%.
Star Clusters Megapays™ has a maximum base game win of 1340x your stake. During the free spins, you can earn as much as 27,050x your stake without including the progressive jackpots.
Yes! You can try Star Clusters Megapays™ for free right here, on our page. Because you’ll be playing with demo credits, no real wins or losses can occur, but it’s a great exercise before moving to real- money play!
