About Star Clusters Slot

The Star Clusters online casino game has an interesting format that can lead to successive wins if groups of matching symbols are formed. Those that form a winning combination will be removed and replaced by four smaller ones, which is a neat innovation when it comes to the Reactions feature found in other Big Time Gaming slots.

There are a variety of gemstones that make up the game’s icons, with Topaz, Citrine, Spessartine, Emerald, Sapphire, Ruby, and Amethyst. There are also two wild symbols, one standard and one Gold, which can upgrade the accompanying multiplier that is attached to each spin.

Play Star Clusters slot on mobile, desktop or tablet. You can also play Big Time Gaming's groundbreaking Bonanza slot right here at Bet UK too.

How to Play Star Clusters Slot

Total Bet

Use the green ◄ and ► arrows to the right of the reels to set your total bet for the next spin.

The paytable and settings can be accessed through the ‘≡’ button in the bottom left of your screen.

Star Clusters Slot Features


The Reactions feature occurs after every winning combination, whereby all the symbols that formed it will be removed from the reels. On the first Reaction, smaller symbols will replace them, with four appearing for each position. These new icons can also form winning combinations, although they won’t split any further.

Free Spins

After five or more Reactions, the Free Spins bonus round will be triggered. You’ll be awarded two to play through as standard, plus an extra spin for each additional Reaction that triggered the round. The Gold wild multiplier is active during the Free Spins bonus, where it will award an extra spin each time it reaches a multiple of 10.

Bet UK Star Clusters Slot Review

Star Clusters is an outstanding slot game from Big Time Gaming, that feels like a spin-off from the Megaways structure, where Megaclusters can lead to multiple wins from a single spin. The Gold wild multiplier is a useful extra that can enhance payouts as well, and the fact that it carries over to the Free Spins bonus round can lead to wins of 23,960x your stake. Cluster systems have proven popular in games such as Honey Rush and Sweet Bonanza, but Star Clusters brings something new to the function.
