How to play

Star Clusters Megaclusters slot uses the brand new Megaclusters engine from Big Time Gaming. The good news is that it’s very easy to understand and once players get started spinning the game, it will become much clearer. When the game first starts, there will be four rows and four columns. Each time a winning combo is formed with five or more of the same symbols either horizontally or vertically adjacent, another four smaller symbols will replace these symbols. This means there are even more chances to achieve wins.

Arrows to the side of the reels allow you to toggle your bet per spin and you can use the autoplay function to set your bet per spin and the number of spins you want, allowing the game to then play automatically. Bets per spin start from just 10p and rise to £20.

The gem symbols on the reels of this game are:

  • Purple
  • Blue
  • Red
  • Yellow
  • Orange
  • Green
  • Turquoise
  • star wild


The maximum win in the base game of Star Clusters Megaclusters is 12,407x your total stake.

Special Features

There are three special features in Star Clusters Megaclusters which are:

  • a reactions feature
  • a gold wild multiplier feature
  • a free spins feature

Big Time Gaming is known for including the reactions feature in their slot games and Star Clusters Megaclusters is no different. Each time a winning combo is formed, these symbols will split into four smaller symbols which provides more opportunities to form winning combinations. Each time this process happens, symbols on top that are the same size will fall, which gives space for more new symbols. The round ends when no new winning combinations are formed.

Watch out for the colourful star symbol as this is the gold wild multiplier. The multiplier starts at 1x and each time this symbol is part of a winning combination, this feature is triggered and the multiplier will increase by one. This process continues and can help players achieve even bigger wins. It will reset after each spin but will continue if the free spins round is triggered. During any spin, the maximum number of gold wilds that can appear is two.

Lastly, there is a free spins feature that is triggered when at least five reactions trigger. Players will be awarded two free spins and if you got more than five reactions, you’ll get one extra free spins for each one. Players can also get another two free spins if the gold wild multiplier hits a multiplier of 10 which means, for example, when it hits 10x, 20x and so on.

Graphics and Sounds

Star Clusters Megaclusters is quite simple in its design and has a gemstone theme similar to other popular slot games on the market such as Starburst. Behind the reels is a plain background of changing colours such as orange, blue, purple and red. On the reels, all symbols are gemstones in a variety of shapes and colours.

Lively disco-style music plays in the background as you spin which adds some extra oomph to the game.


Star Clusters Megaclusters is a great addition to the Big Time Gaming catalogue and for players who have previously enjoyed the Megaways games, this is another mechanism that offers exciting gameplay. Although the design is very simple and not likely to blow anyone away, the unique gameplay and range of bonus features, including the reactions feature and multiplier wilds, is sure to be attractive. Don’t miss out on trying this thrilling new mechanism and give its reels a spin today.
