Star Clusters Megaclusters appeared on the market in 2020 thanks to the developer Big Time Gaming. This is the first game with the completely new Megaclusters mechanic, unlike any previous release by the studio. The slot's RTP is 96.54%, and the volatility is high. Powerful win streaks with a rising multiplier are guaranteed here.

The slot's theme is dedicated to space, and instead of paylines, clusters work here. This is the main feature of the game: neon cascades with an accumulating multiplier, which is enhanced by the golden wild and does not reset during the bonus game. In combination with free spins and multi-level bonuses, Star Clusters becomes an even more dynamic game.

What Makes Star Clusters Megaclusters Different From Other Slots?

The developers of Star Clusters Megaclusters have focused not on classic free spins, but on progressive mechanics. This approach can bring players winnings through cascades, an expanding grid, and an accumulating multiplier. Let’s take a closer look at how all the key features of the game work.

  • Megaclusters. This mechanic is activated with every win. The symbols involved are split into 4 smaller ones, increasing the grid density and creating more chances to form new clusters. In the base game, the grid can expand up to 8x8 (64 symbols), while in free spins mode, it can grow up to 256. With Megaclusters, you can trigger a chain reaction of a dozen different bonuses in a single spin.

  • Avalanche. After each winning combination, the involved symbols disappear, and new ones fall from above to take their place. This chain reaction continues as long as clusters keep forming, making every spin potentially a generous payout series, especially when combined with Megaclusters.

  • Gold Wild. The game features a standard wild in the form of a star, which substitutes for any basic symbols, as well as a special Gold Wild. This wild only appears after wins and acts as a catalyst for increasing the multiplier. Each time the Gold Wild appears in a cluster, the multiplier increases by +1. The most important feature is that this multiplier is carried over into free spins, where it continues to accumulate, helping to secure big payouts.

  • Free Spins Round. It is triggered after 5 or more consecutive cascades within a single spin. For the first 5 reactions, the player receives 2 free spins, and for each additional cascade, they get one more. During the bonus game, the grid expands to 8x8, and the multiplier from the base game is not reset - it continues to grow. For every +10 to the multiplier, 2 additional free spins are awarded, allowing the bonus round to be extended and increasing the potential payout.

How to Play Star Clusters Megaclusters?

The developer created Star Clusters Megaclusters for a wide range of players: both experienced gamblers and newcomers will easily get the hang of this slot. To make your gameplay as simple as possible, follow our guide. Below, we explain how to properly start the slot and make the most of all its features.

Select Your Bet

On the right side of the game screen, you’ll find the control panel, where you can adjust your bet for each round. Use the left and right arrows beneath the amount indicator to select a bet between €0.20 and €20 per spin.

Spin the Reels

You can start the game in two ways: manual or automatic spinning. In the first case, you need to click the green Play button and repeat this action every round. In the second case, simply click the button with the circular arrows — this is the Autoplay mode, which allows you to choose up to 100 automatic spins. You can also set win and loss limits to control the autoplay feature.

Watch for Clusters

Winnings in Star Clusters Megaclusters are formed when 5 or more identical symbols land horizontally or vertically. After that, the Megaclusters mechanic is activated, and the winning symbols split into 4 smaller ones, with new symbols falling from above.

Play in Demo or for Real Money

You can test Star Clusters Megaclusters for free if you're not ready to take a risk yet. To do so, simply select the demo mode at any casino where the game is available and start the slot. The game rules and RTP are the same in both modes.

My Opinion on Star Clusters Megaclusters

With thousands of slots under my belt, Star Clusters Megaclusters stands out thanks to its unique mechanic. Megaclusters give you a rare feeling of wild chaos, as the grid changes, cascades keep coming one after another, and the wins grow before your eyes.

What particularly grabs me about this mechanic is the Gold Wild, because the multiplier quietly accumulates, only to suddenly appear during the free spins. And while the volatility in the game is high, it’s fair: if the wins come, they come with a significant boost. The only other slots to compare Star Clusters Megaclusters to are probably Reactoonz and Jammin Jars, as they are also dynamic cluster-based games. But Star Clusters has a more versatile grid, so if you enjoy complex mechanics, this game is definitely for you.

FAQs

1.

In this hit from Big Time Gaming, the developer introduced one of its most unique features. Every symbol in a winning cluster breaks into four smaller symbols, expanding the size of the game grid.

2.

To create a winning cluster, players need at least five symbols that are touching either horizontally or vertically.

3.

Every time a winning cluster appears, the Multiplier increases by 1. With consecutive wins, it keeps climbing, boosting the payouts of any new combinations.
